Treatments for Mouth Ulcers, Canker Sores

My nine-year-old suffers from very severe mouth ulcers. Have you any idea what causes this or what cures it?

Treatments for Mouth Ulcers, Canker Sores

The most common form of recurrent painful mouth ulcers in an otherwise healthy person is called aphthous (pronounced aff-thiss) ulcers or “canker sores.” These ulcers are small, occur anywhere inside the mouth and can last for up to two weeks. They often occur in children who have family members who have also had mouth ulcers. They may recur over a period of weeks or months. Some children and adults have almost continuous symptoms.

The cause is not certain, but the current thinking is that the ulcers are not caused by infection. No specific treatment to eliminate the ulcers exists, although your pediatrician may prescribe a liquid form of the antibiotic tetracycline, small amounts of the topical numbing medicine viscous lidocaine or a mixture of Benadryl and Maalox to treat the discomfort caused by the ulcers.

A child who has oral ulcers in combination with lesions of the skin, eyes, joints or genitalia may have a rare condition called Behcet’s syndrome.
