Canker Sores

What are mouth ulcers?

Mouth ulcers are one of the most common diseases of the oral mucosa. This is an inflammation characterized by superficial sores on the oral mucosa, technically called aphthous stomatitis.

The ulcers (round or oval) are usually smaller than 1 cm but can be larger. They usually develop on the inside of the cheek or on the inner surface of the lips, on the tongue or on the roof of the mouth. They are characteristically white-gray or yellow in color, bordered in red due to inflammation. A burning sensation, itching, or pain may accompany it. According to research, 20% of the population are affected, but there is no risk of infection.

How are mouth ulcers formed?

Experts disagree about the causes of mouth ulcers. Only a few risk factors are known, the most important of which are genetics, allergies or sensitivity (e.g. to sodium lauryl sulfate, which is found in toothpaste and oral hygiene products, and to foods such as cinnamon, cheese, citrus fruits, figs or pineapple), stress, menstruation, weakened immune system, anemia, fatigue and iron, folic acid and vitamin B deficiencies.

Canker sores can also result from a burn from consuming hot food or drink. They often occur when we injure the oral mucosa through a bite or careless brushing of our teeth.

How do I get rid of mouth ulcers?

A doctor's visit is not necessary because of the aphthae (except in severe cases). The use of hyaluronic acid is recommended as it has anti-inflammatory and analgesic properties, thus helping to alleviate discomfort.

Usually, the pain and discomfort in the mouth are relieved on their own after a few days, after which the mouth ulcers disappear after about two weeks.
