In brief: Canker Sores?
Canker sores (ulcers in your mouth) can be easily treated over the counter with things like kankaid that provide a pain relieving covering for the sore that aids healing.
Ulcers outside of your mouth (cold sores caused by the herpes virus) can be treated otc with drugs like abreva. Herpes can also be treated with prescription drugs to relieve symptoms, so consult your doctor.

In brief: Duration?
Few days. It will likely go away.
Ask pharmacist for OTC preparations If longer than 10 days, see oral surgeon to rule out cancer.
