Aphthous ulcer

Aphthous Ulcer

An aphthous ulcer, also known as a canker sore, is a type of oral ulcer that is not caused by the herpes simplex virus. These ulcers are typically small, shallow sores that appear inside the mouth, often making eating and talking uncomfortable.

Causes

The exact cause of aphthous ulcers is unknown, but they are thought to be triggered by a variety of factors. These can include stress, certain foods, hormonal changes, or minor injuries to the mouth. Some people may also have a genetic predisposition to developing aphthous ulcers.

Symptoms

Aphthous ulcers are usually round or oval with a white or yellowish center and a red border. They commonly appear inside the lips, cheeks, or at the base of the gums. Symptoms can include a tingling or burning sensation prior to the appearance of the ulcer, painful sores in the mouth, and in severe cases, fever, fatigue, and swollen lymph nodes.

Treatment

While there is no cure for aphthous ulcers, treatment can help reduce pain and inflammation, shorten the ulcer's duration, and prevent recurrence. Over-the-counter topical medications and mouth rinses may provide temporary relief. If ulcers are large, persistent, or unusually painful, a doctor or dentist may prescribe a stronger medication.

Prevention

Preventing aphthous ulcers can be difficult due to their unknown cause. However, avoiding foods that seem to trigger outbreaks, maintaining good oral hygiene, and managing stress can help reduce their frequency.
