1. Q: Is a canker sore the same as oral herpes?

A: Canker sores are painful ulcerations that occur inside the mouth, inside your cheek, or on your tongue. They’re an autoimmune response and typically a reaction to chocolate, citrus, or wheat. Canker sores will not respond to anti-herpes medications or approaches.

Oral herpes appears as small blisters or lesions that are very painful and typically affect the lips. Oral herpes is caused by the Herpes Simplex Virus Type 1.
