What is an apthous ulcer? Physically, it’s a shallow lesion that develops in the mouth.
It is quite common and it is similar to the body’s reaction to an allergen. Triggers can vary. Some common triggers are stress, acidic foods, trauma, and ingredients in mouth products. It is not known to be a viral nor a bacterial infection. They do not occur on the outer surface of the lips and they are not contagious.
Unfortunately, they can be painful making eating and talking difficult. Most of the ulcers resolve on their own in 2 weeks. Applying a topical numbing gel can help with discomfort for children that are old enough for it. It is recommended to avoid spicy or acidic foods while the healing is in progress.
