In brief: Symptom management

The cause of apthous ulcers (canker sores) is unknown, and treatment is limited to symptom management.
Historically, dentists cauterized these lesions with products like silver nitrate or debacterol, but this strategy may delay healing. Use of a topical anesthetic product, available for purchase over the counter at your local pharmacy, is helpful in relieving pain until healing sets in.

In brief: Inside or outside?

If on the inner lip kenalog (triamcinolone) works well, if outside of lip, try denavir/zilactin.

Pencyclovir (Denavir) is an antiviral medication, and is of no value in treating a non-viral lesion like a canker sore.
