Diagnosis matters
Aphthous ulcers and herpetic lesions can resemble other oral conditions, so treatment begins with an examination.
Aphthous ulcers and herpetic lesions are different conditions, but both can be painful. After a careful diagnosis, focused laser treatment may be used to support comfort and healing for an active oral lesion.

Herpetic lesions, commonly called cold sores or fever blisters, are contagious lesions associated with the herpes simplex virus and usually develop on or around the lips. Aphthous ulcers, commonly called canker sores, occur inside the mouth and are not contagious.
Laser care does not remove herpes simplex virus from the body or guarantee that an aphthous ulcer or herpetic lesion will not return. The goal is focused symptom support after the dentist confirms the lesion type and whether laser treatment is appropriate.

A round white or yellow sore with a red border may be an aphthous ulcer, but an exam helps rule out other causes.
Herpetic lesions often begin with tingling or burning before fluid-filled blisters appear around the lips.
