Mouth ulcers are disruption of the oral mucosa with round or oval shape, surrounded by a bright red halo. Their bottom is whitish (yellowish) colour.
They are an expression of the disease aphthous stomatitis. It is most often caused by viral and microbial infections (influenza, scarlet fever, stomach disorders) and also by bite inside the mouth. It is mostly children and rarely adults who suffer with mouth ulcers. They appear seasonally (winter, spring) and have acute or chronic course of development.
Acute aphthous processes are the result of exposure to infection and reduced immune defenses of the organism, but also a result of bite inside the mouth. They begin acutely with fever, loss of appetite, fatigue and painful dry mouth. A check on the cheeks, lips, side edges and bottom surface of the tongue shows several small round ulcers. They are very painful when eating and speaking. They look like white patches on the reddened mucosa.
In ulcers developed after biting, the form may be different depending on the biting. There is unpleasant breath. Submandibular lymph nodes are enlarged and painful and there may be an elevated temperature. It takes 10-12 days to recover after using local and general treatment. Long-term immunity is built.
The chronic mouth ulcers often relapse (repeat). They appear in endocrine disorders, allergies, treatment of vitamin deficiencies, infections, poor oral hygiene, etc. They occurs with milder symptoms. In the mouth there are 2-3 visible sores on the top and side edges of the tongue, the lining of the lips, cheeks and soft palate. They are painful when eating and speaking. It takes a week to heal. Frequent recurrences could be due to poor oral hygiene, tartar, sharp edges of untreated teeth, dentures, etc. When aphthous conditions are due to common illnesses this requires consultation with the relevant specialist.
