Nearly everyone has contracted Herpes simplex I virus but it only causes cold sores in a small number of people.

Canker sores: are not pleasant and can be very painful. Canker sore is the most common oral lesions. Individual ulcers typically last 1-2 weeks. The condition is idiopathic (the cause is not known) and recurrent aphthous ulcers are usually self-limiting. Your dentist may prescribe an antimicrobial mouth rinse corticosteroid ointment to control the pain and irritation.
