An inflammation of the mucous lining of any structure related to the mouth like the tongue, gums, throat, cheeks, lips or the roof or floor of the mouth is called stomatitis. There is redness, swelling, occasional bleeding, and bad breath. It can affect infants as well as older people.
  • Mycotic stomatitis: Also called an oral thrush, this is an candida infection of the mouth and other oral areas. In infants it may occur particularly after a course of antibiotics. Those with a weak immune system are generally susceptible.
  • Gingivostomatitis: It is characterized by the inflammation of gums and is caused by the herpes simplex virus.
  • Stomatitis nicotina: This is mainly caused by smoking cigars, cigarettes, and pipes. It can be identified by the presence of red bumps on the roof of the mouth.
  • Herpetic stomatitis: It is caused due to a viral infection of the mouth, and is marked by the presence of ulcers and inflammation.
  • Aphthous stomatitis: Here, small ulcers appear inside the lips, on the cheeks or tongue.
  • Chronic ulcerative stomatitis: This condition is characterized by ulcers.
  • Blood in saliva
  • Oral bleeding

  • Chronic stomatitis is caused by anemia, leukemia, neutropenia, vitamin C deficiency, agranulocytosis, and auto-immune diseases.
  • Patient's history that comprises a dietary deficiency, a systemic disease or contact with materials leading to an allergic reaction.
  • Physical examination of oral lesions and other skin problems.
  • Blood tests to infer any infection.
  • Microscopic evaluation of the scrapings of the lining of the mouth.
  • Cultures of the mouth to detect any infectious agent.
  • Maintain a good oral hygiene.
  • Avoid eating sharp-edged foods like tacos, peanuts and potato chips.
  • Use soft-bristled toothbrush and careful washing of teeth and gums.
  • Correct ill-fitting dental appliances or sharp teeth.
  • Take medication for infectious conditions and to overcome vitamin B12, iron or folate deficiency.
  • Use cotton-tipped applicator for aphthous ulcer.
  • Low-power treatment with a carbon dioxide laser for recurrent aphthae.
  • Use tetracycline antibiotics or corticosteroids for aphthous stomatitis.
  • Use valacyclovir for stomatitis due to herpesviruses.
  • Use topical anesthetics like a 2% lidocaine gel or a protective paste (Orabase) or a coating agent like Kaopectate.
  • Resort to botanical medicines like calendula in tincture form and diluted for a mouth rinse.
One can even resort to topical treatments that include corticosteroids, anesthetics, antibiotics, protective coatings, antihistamines and physical measures like cautery.
  • 5 ml of 2% viscous lidocaine is mixed with 10 ml water and used as a rinse.
  • Carboxymethylcellulose paste with or without 1% triamcinolone qid decreases irritation of local lesions.

Chemical or physical cautery relieves pain. Silver nitrate sticks are less effective than low-power, defocused, pulsed-mode carbon dioxide laser treatments.
