However, when inserted into the oral cavity, the tongue continues to appear scalloped minutes later due to swelling body pushes on the tooth surface. If the tongue is not swollen or bulging body, but still has teeth marks, it is a physical problem of distribution of the teeth themselves.

If there is a deficiency of qi and yang, the tongue can not firmly hold its proper shape, and increasingly weakens. The weak tongue then relaxes to the bulging shape and does not have enough energy to avoid pressed to the teeth, resulting in teeth marks. Furthermore, swelling of the tongue as well as due to excess moisture accumulated in the body.

Excess moisture in the TCM is water retention. The TCM spleen represents the overall function of the gastrointestinal tract. Digestion is the transport and transformation. If the spleen qi deficiency has its own, you can not properly convert food and liquids we eat into energy, which results in the accumulation of excess fluid. Therefore, the tongue casserole is often seen as a marked swelling and teeth at the same time.

Scalloped Tongue – Treatment Symptoms and Causes

Scalloped tongue refers to the edge of the teeth marks, and is also known as Indian tongue.

It is usually caused by big fat tongue or a margin of compression caused by the teeth. The tongue is an anomaly, which has a lot of guidance for clinical diagnosis and treatment significance. It’s easily identified by a scalloped appearance, and are subject (such as food, medicine, etc.) to be affected by external factors.

Scalloped Tongue Causes

Chinese medicine believes the tongue is tightly tied to spleen health. Enlarged tongue is caused by Yang Qi, or when the spleen cannot exude moisture. So scalloped tongue is caused by mainly spleen dampness. If pale and moist, it is alpine dampness; pink and scalloped, mostly spleen qi deficiency.

Scalloped tongue, or big fat tongue is caused by oppression of the tooth edge; the scalloped tongue so often associated with big fat tongue, or spleen dryness deficiency. If the tongue is pale and moist, the spleen suffers from dampness.

More often the spleen can not be shipped wet, so wet tongue and resistance to big fat tongue are formed by extrusion dentition associated with fat and tender tongue – on the one hand because of the tongue body edema, or the yang of the spleen and dampness, on the other hand due to the tongue muscle relaxation, mouth shortage, and spleen qi deficiency.

Clinical studies found that there are a lot of people scalloped tongue have the absence of disease, but they were in a healthy state, so the Chinese medicine says Qi (wet weight) is not sick weight, but the state of the body’s blood being imbalanced, which Western medicine often mistakes as disease-free, but in Chinese medicine is considered unhealthy.

Other Causes of Scalloped Tongue

Epidemiological studies of Gray scalloped tongue in 318 cases closely followed scalloped patient’s diet, living habits, symptoms, conducted a survey and found a low incidence of this anomaly in those who like to eat salty foods.

Often tea drinkers in Japan have a tendency to be scalloped tongue prone. The symptoms associated with Qi and lassitude, spontaneous, anorexia and other significant differences were not there, but rather symptoms of indigestion like belching, stomach heaviness, and bowel discomfort. Thus, the relationship with scalloped tongue Qi Deficiency Syndrome is not clear, but the relationship with the dampness of scalloped tongue should be studied more closely.


Clinical manifestations of scalloped tongue are:

– Pale moist teeth marks, or alpine dampness;

– Pink and scalloped, which signifies qi deficiency;

– Mouthful of red and swollen, scalloped edges, mostly hot and humid phlegm Yongzhi;

Short and yang qi deficiency can be divided into two types:

⑴ Deficiency: On the tongue, thin white fur, fat and tender tongue, tongue scalloped edges, indistinct white or pale yellow atrophy, shortness of breath, slurred speech, top-heavy body swelling, malaise, fatigue, spontaneous , eating less, bloating after eating, Yu Tu Pan evil, loose stools diarrhea, and weak pulse.

A Therapeutic cure for this is Buzhongyiqi tea.

⑵ Yang type: Tan White tongue, tongue moist and more fluid, or the tongue water slide, big fat tongue round tender, with scalloped edges. Pale or Qinghei, lassitude, fatigue hi lying, pale mouth thirst, anorexia, belly Leng Tong, Wen Fang Shu , stomach cold, clear urine, eye swelling, and Micro pulse.

A therapeutic cure for this is Wenbu Yang Xin tea.

Scalloped Tongue Treatment

In terms of diet, if the scalloped tongue is pale, in the choice of food, you can choose vegetables like barley, yams, pumpkin, sweet potatoes, chestnuts and other food to eat. Try not to eat raw fruits and cold drinks, because it will damage the spleen Yang, resulting in heavier wet.

Also take into account whether liver discomfort is present. If yes, then you have an excess of qi. Reorganize the liver through the use of roses, soaked in water drunk as a tea, can be a miracle cure. Roses ration the role of qi in the blood, but remember not to use them during pregnancy.

You can use Atractylodes, Chinese yam, lotus seeds and meat , etc., to regulate the spleen. Leeks can wick spleen moisture away, such as when you can put a cooking barley, and barley regulates the role of wet very Well. Some friends like to cook barley and rice half and half, the result of which eliminated thick and greasy tongue within two weeks.

You can properly use some safflower, angelica root, Salvia blood circulation, such as drugs, to start bleeding more easily than usual, and so more easy to promote the smooth flow of blood.

However, make sure the blood circulation of the drug is not more than you can handle. You should be under the guidance of a doctor to use a local, so that it more secure.

Scalloped Tongue in Cancer Patients

Domestic scholars relationship with scalloped tongue syndrome reported much. The 77 cases Zhang Qi Deficiency Syndrome patients with organs Qi and partial victory by triple burner into cardiopulmonary Qi deficiency group, spleen qi deficiency group, kidney virtual groups.

Observations show that: Qi Deficiency Syndrome characteristics mean the tongue is fat, and have scalloped, about 23 more than the patient’s qi deficiency, the center Qi Deficiency Syndrome accounted 5.65% and 10.0%, respectively, compared with control group not only have a high degree of statistical significance, but also higher than the stomach, kidney deficiency by. Qian investigating 25 cases of patients with scalloped tongue, to a maximum of qi deficiency syndrome, a total of 285 cases.

Scalloped tongue disease research and clinical studies indicate that scalloped tongue be found in a variety of diseases. and other control observation of 168 cases of gastric cancer patients and 200 healthy people of the tongue, scalloped tongue results of gastric cancer accounted for 23.2%, compared with the healthy population significantly different. Xu Equal to 326 cases of tongue cancer patients analyzed, the number of cases found in the tongue and teeth marks were big fat is high, and the higher the tongue in the order of lung, stomach, esophagus, cardiac, liver, breast, cervical cancer, nasopharyngeal cancer, colorectal cancer.

The Anti-Cancer Association in 19 cancer patients found that big fat tongue, thin tongue, scalloped tongue  showed that, of cancer patients with big fat tongue, scalloped tongue patients were in the majority.

Chen Weimin and other surveys 204 cases of chronic gastritis patients and found pale tongue with teeth marks to merge ulcers were more common, accounting for 43.48% of different cases of upper gastrointestinal diseases were analyzed with 300 cases found in inflammatory lesions in the superficial – atrophic gastritis and atrophic gastritis and pale pale tongue with scalloped tongue were 414%, 36 7%, while the superficial gastritis and pale pale tongue with scalloped tongue was 22.2%, are more significant differences between the two (P <0 01).

In peptic ulcer disease , and duodenal ulcer with pale pale and scalloped for more than 6.8%. EMERGENCY IN on 137 cases of aplastic anemia patients with clinical observations suggest that the tongue, big fat tongue aplastic anemia patients (16.79%), scalloped tongue (29.93%) was significantly higher [15]. In addition, 01 cases of hypertension patients tongue scalloped edges were observed, the results of the incidence of hypertension group scalloped up to 42.29%, compared with the control group (20.5%) were significantly different (P <0.001). This and some foreign scholars believe scalloped tongue seems to be more common in hypotension contradictions, need further verification.

In a Survey of 425 cases of patients, the follow groups were found more at risk of scalloped tongue disease:

⑴ Those with lower the pH of body fluids, such as renal tubular acidosis , kidney stones;

⑵ renal dysfunction, sodium retention, such as renal transplantation, renal disease, systemic lupus erythematosus , he caused the water such as kidney stones can also affect kidney function;

⑶ make globulin immune dysfunction diseases, such as renal transplantation, systemic lupus erythematosus, thyroid disease glomerular disease, liver disease, heart disease, pericardial and pleural disease;

⑷ anemia diseases, such as iron deficiency anemia, pregnancy and postpartum, gynecological diseases;

⑸ immune function disorders, such as leukemia, cancer, etc.

Japanese scholars Muramatsu Mu believes scalloped tongue were mainly chronic gastritis , diabetes, hypotension, hay fever , chronic hepatitis , knee edema, menopausal disorders such as so-called adult chronic disease.

Scalloped Tongue and Microcirculation

Microcirculation research money, such as heart and other mushroom-shaped tongue and the tongue papillae count microcirculation studied scalloped depressions and protruding tongue area blood supply and nutrition, and to compare with the normal pink tongue found scalloped tongue microcirculation changes in the following areas: ⑴ blood disorder.

Mushroom-shaped tongues reduce microvascular plexus, capillary artery vein arm slender arm ratio, especially in the performance of these two scalloped tongue protrusion is more apparent. Alien amount representing an increase of microvascular plexus normal. ⑵ local hypoxia and undernutrition.

Number of mushroom-shaped nipple tongue blood for a positive correlation between the number of scalloped tongue fungiform papillae lower than normal. ⑶ tissue edema.

Tongue microcirculation capillary tube visible inside the loop fuzzy tongue papillae and oozing, hemodialysis ultrafiltration (dehydration) after the pipe loop clearer, leakage reduction, so the tongue is a capillary tube loops oozing fat causes great scalloped tongue of one of [3].

Pathological Symptoms of Scalloped Tongue

Pathological microscopy and electron microscopy methods isolated chunks of scalloped tongue protrusions, the recess and the performance of normal tissue and cell morphology of the tongue side. This found that the main pathological symptoms of scalloped tongue are:

⑴ thinning of the cortex. In normal tongue epithelium thickest, followed by the recess, the projection of the thinnest, which may be related to the local nutritional status;

⑵ change within the rough endoplasmic reticulum. In the basal and prickle cell layer, rough endoplasmic reticulum reduction, expansion, loss of ribosomes, these manifestations suggestive of rough endoplasmic reticulum protein dysfunction is one of the manifestations of cell damage;

⑶ wire tension reduction. Scalloped tongue reduce tension wire, prickle cell and basal cell gap increases, was sparse mesh-like, finger-like papillae desmosomes reduction, indicating a bad connection scalloped tongue cells;

⑷ cell tissue edema. Mainly caused by lack of nutrition partial increase cell membrane permeability, water liquid spill blood vessels penetrate cells. On the other hand, poor lymphatic drainage, can not take away excess moisture;

⑸ lack of elastic fibers. Lack of traction of the fibers caused by reduced tolerance effect, it is made by serrated teeth oppressed.

Scalloped tongue fungiform papillae significantly increased compared with normal diameter, due to the inherent level of water inside the tissue fluid retention. Microcirculation microscope with a deficiency in patients with uremia same tongue found the same microcirculation Hemodialysis, 125 cases of pre-dialysis patients with scalloped tongue were 108 cases much fat, fat and scalloped tongue slightly reduce the extent of dialysis.

What Is Scalloped Tongue?

In professional terms, tooth marks around the edges of the tongue is called a “scalloped tongue”. This is one sign that a person might be clenching and grinding their teeth, especially at night during sleep. 

Ask your dentist if there are other signs that you might be doing this. If so, you can have a custom nightguard make to protect your teeth and jaw.

10 Common Causes of Scalloped Tongue:

1.) Toothed tongue – frequent change of the form of tongue, in which the edges become scalloped shape. This change in shape is caused by an unusually high pressure on the fabric of tongue, such as bruxism, the habit of sucking the tongue against the teeth, increasing the size of the tongue.

2.) Commonly observed both scalloped edges, but it may be on one side only or limited tongue that portion which is pressed down directly to the teeth. As a result, the pressure on the edge of the tongue are printed contours of the teeth in the form of oval depressions, which sometimes bordered by towering white scalloped crest.

3.) Often combined with a toothed tongue distinctly stands a white line on the mucous membrane of the cheeks, which is formed by the negative pressure generated in the oral cavity in patients who have a habit of sucking the tongue against the teeth. Toothed tongue observed in lesions of the temporomandibular joint, systemic diseases, such as acromegaly, and amyloidosis, hereditary diseases, such as Down’s syndrome, as well as in healthy individuals. This change in the form of tongue does not represent any danger to the health and does not disturb the patients. The treatment is to eliminate bad habits.

4.) If the language seems to be pale and swollen or sore sometimes, then it may be an indication of an underlying health condition. Sometimes the tongue tends to swell and expanded due to an infection or any health related disorder. This condition is known as scalloped tongue.

5.) According to Traditional Chinese Medicine (TCM), a fissured tongue or scalloped occurs when there is a deficiency of yang or qi (pronounced “chee”) in the body.

6.) A rough crenated language or may be caused due to a deficiency in the secretion of thyroid hormone, which can lead to an active thyroid, also known as hypothyroidism. The thyroid gland is the master gland controls many body functions, including metabolism. The decrease in the functioning of the thyroid gland can cause enlargement of the glands. Some glands also change its shape or size decreases, and this can lead to inflammation of the tongue.

7.) A swollen or cracked tongue can result from water retention in the body. Excess accumulation of moisture or water may be an indication of qi deficiency (or deficiency of the spleen), which can lead to failure of proper food processing and liquid energy. This will result in crenated language is seen as bloated and marked teeth.

8.) Another factor causing cracks little is known on the tongue is sleep apnea, which is a sleep-related disorder. This condition can cause alterations in the pattern of breathing during sleep. This condition is caused by the tongue falls into the oral cavity, while sleeping. Teeth tend to put pressure on the tongue that can leave groove as prints or fissures on the tongue.

9.) In the temporomandibular joint, also known as TMJ syndrome is also one reason to notice a swelling in the tongue. In TMJ syndrome, the lower jaw is unstable and to support the jaw, the teeth must always be closed. This clenching leads to the formation of grooves on the tongue, which makes it look like a swollen tongue.

Treatment Options

Scalloped tongue or crenated may result from deficiency of thyroid hormones. There symptomatic treatments for symptoms associated with a deficiency of available spleen. There are many prescription free of hormones available in the market in order to increase thyroid hormones. For this tongue problem is caused by temporomandibular joint syndrome, it is advisable to consult a dentist ATM, which can diagnose the disease and provide appropriate treatment.

Although there is no known cure or treatment for scalloped tongue, this condition is harmless. The swelling may fall over time, after taking supplements to bring back the hormone levels to normal, which can help the smooth functioning of the spleen and digestive system.

What to Ask Your Dentist Before Treating Scalloped Tongue

Most people, when their tongue is irritated, can’t seem to keep from rubbing it against the teeth to make it feel better (sort of like scratching an itch); however, this usually makes things worse. Over-the-counter medications such as OraBase or Zilactin can be applied. These materials act like a bandage and help to protect the ulcerated surface of the fungiform papilla. 

Lie bumps are not contagious and the discomfort is relatively minor. Typically these lesions heal within a few days with no treatment. If they do not, then you should be seen by an oral pathologist. 

When it comes to make that decision these questions should be asked:

1) Airway Breathing – will extraction or not extracting of teeth help add to optimal function/stability or bring physical impairment/dysfunction?
2) Tongue Posture – will extraction or not extracting of teeth help add to optimal function/stability or bring physical impairment/dysfunction?
3) Maxillary to Mandibular Alignment – will extraction or not extracting of teeth help add to optimal function/stability or bring physical impairment/dysfunction?
4) Head, Neck and Cervical Posture -will extraction or not extracting of teeth help add to optimal function/stability or bring physical impairment/dysfunction?
5) DentoFacial/ Esthetics – will extraction or not extracting of teeth help add to optimal function/stability or bring physical impairment/dysfunction?
6) Psycho/Emotional Stability – will extraction or not extracting of teeth help add to optimal function/stability or bring physical impairment/dysfunction?
7) Structural Strength and Quality of Physiologic Rest – will extraction or not extracting of teeth help add to optimal function/stability or bring physical impairment/dysfunction?
8 ) Temporomandibular Joints – will extraction or not extracting of teeth help add to optimal function/stability or bring physical impairment/dysfunction?
9) Focus, Concentration, Learning, Working Abilities – will extraction or not extracting of teeth help add to optimal function/stability or bring physical impairment/dysfunction?
10) Autonomic (Parasympathetic/Sympathetic) System – will extraction or not extracting of teeth help add to optimal function/stability or bring physical impairment/dysfunction?

Perhaps the discussion should also focus not on whether to extract or not to extract, or whether nature can or cannot accommodate 32, 28 or 24 units of teeth, but on whether (whatever combination of teeth) the diagnosis and treatment method will be enhancing the function and health of the ortho patient or would the diagnosis and treatment further physiologic impairment.

I don’t believe nature’s design is in support of impairment of anyone.

Encyclopedia of Scalloped Tongue and Other Tongue Abnormalities

Around the end of the fourth week,  the development of the language begins with a somewhat triangular medial elevation on the floor of the primitive pharynx, just rostral to the lingual blind hole, called the medial tip of the tongue; represents the first indication of the development of this organ.

Abnormalities of the tongue therefore also project to the fourth week, although rare except cracking and hypertrophy of lingual papillae that are characteristic of children with Down syndrome.

The alterations that can occur are:

  • Lingual frenulum: The frenulum is frequently constitute a pathological element, which is characterized by a strong cord, which starts on the underside of the tongue; in the vicinity of its apical end, runs through the middle third, turns forward, and inserted in the midline of the mucosa of the floor of the mouth, unlike the tongue tie since it not only involves setting the language also interincisivo lower diastema.
  • Ankyloglossia or tongue tied: In a malformation in its overall shape is due to the binding of the tongue to the floor of the mouth, which is the exception. Is rare (1 per 10,000 births) although more frequent in part, in which the language has a very short or inserted too close to the tip lingual frenulum. It is accompanied by disorders of lactation and dyslalias that may go unnoticed for a long time and in later ages, adaptability and difficulties in retaining Prostate thesis . Usually not definitely affects speech, except for cases of total Ankyloglossia in which may be indicated frenilectomia
  • Bifida or cleft tongue: It is a rare, apparently as a result of lack of alteration fusion of the lateral halves of the body. Partial forked tongue is more common and is manifested by a deep groove on the midline of the dorsal surface of the tongue. Has little clinical significance, except for the possibility of accumulation of residues of food at the base of the slot and development of microorganisms that cause irritation.
  • Lingual thyroid: an injury is linked to the lingual development, consistent embryonic origin in a failure of migration with an incomplete thyroid primordium neck descent. Clinically the lesion is nodular and lobulated, covered by normal mucosa, a posterior position and the lingual base. It is more common in the sex female ..
  • Thyroglossal duct cyst: cysts and fistulas of the thyroglossal duct constitute a congenital condition developed on the persistence of embryological epithelial rests in the path of the thyroid gland, which follows from its appearance in the pharyngeal floor during the third week of life to get in the sixth to final anatomical situation. This route, called thyroglossal duct His or Bochdalek, is obliterated and reabsorbed from the seventh to eighth week of intrauterine life.
  • Lingual thyroid nodule: A lingual thyroid nodule is a rare anomaly characterized by the development of a mass of thyroid tissue in the middle back of the back of the lengua.Embriológicamente, primitive sketch of the thyroid gland originates at the site of the blind hole and migrates bottom along the thyroglossal tract to its final destination in the anterior neck sense.
  • Congenital macroglossia: The macroglosia designates a condition where the tongue at rest protrudes beyond the alveolar ridge. The language is a structure important functions vital as swallowing, phonation and respiration . Participates in the process of development and craniofacial growth. Macroglossia may cause dentomusculoskeletal deformities, create problems in chewing, speech and handling of the airway and instability of orthodontic treatment or orthognathic surgery. The knowledge of the signs and symptoms of macroglossia and their difference with macroglossia relative or pseudomacroglosia help identify those patients who can be intervened on time with a procedure surgical or nonsurgical as appropriate, in order to improve their function , aesthetics and ensure the stability of treatment.
  • Microglossia or hypoglosia: is an abnormally small tongue is extremely rare and usually associated with micrognathia (decreased jaw development and disappearance of the sobresaliencia chin) and defects members (Hanbart syndrome).
  • Fissured or scrotal tongue: Also known as scrotal tongue or plicatta. It is an acquired condition, though there are familial cases; It affects between 5-7% of the population is rare in children, but increases with age; is in both sexes equally and is often associated with geographic tongue. For cracks and grooves can be superficial or deep, horizontal or vertical. It is associated with Down syndrome, Cowden and Melkersson-Rosenthal; the latter is macroquelia by granulomatous cheilitis, fissured or scrotal tongue and facial palsy. It has the following variants: foliácea, cerebriforme, scrotal and transverse. Usually asymptomatic or painful, if presented in its furrows accumulation of food debris and contamination by fungi and bacteria that may cause inflammation and pain. Treatment is symptomatic and requires hygiene , antifungal, if superimposed infection by Candida and psychotherapy .
  • Toothed Language: The language is a traumatic toothed tongue, impressions of the teeth in the lingual edges occur due to macroglosias, bruxism, excessive tooth contact of the teeth with his tongue. Not important and only if that bothers and the patient being aware of it, discharge plates are placed to avoid the traumatic effect.
  • Glossoptosis:  Is the fall of the tongue toward the pharynx; used to be accompanied by other oral malformations and create serious respiratory difficulties.
  •  Alterations Halibut: Unilateral paralysis of the tongue. It may have paralysis of the tongue hypoglossal nerve injury. The paralysis of the tongue direct injuries are relatively common in times of war , civil life because of accidents or consequence of cancer resections.
  • ·Bilateral paralysis of the tongue.
  •  Bilateral paralysis of the tongue is due to injury of the neuron peripheral, there is a degeneration, muscle atrophy and fibrillary contractions. In exchange , lesions in the central neuron missing these three characteristics.   


Around the end of the fourth week, the development of the tongue begins with a medial elevation a little triangular appear in the primitive, tightly rostral pharynx’s floor to the lingual knockout, the tongue’s named medial yolk; Represent the first indication of the development of this organ.
The abnormalities of the tongue consequently project also at the end of the fourth week, although they are rare with the exception of the cracking and hypertrophy of lingual papillas that characteristics belong to children with Down’s syndrome.
