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.

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.

Patience...: Most mouth ulcers are a virus that will run its course. If you do nothing they usually go away in 14 days. If you try to put something on them, they may feel better and will go away in 2 weeks. If something lasts longer then by all means...Go see a dentist or md.

Time: Time is really the only effective treatment for a mouth ulcer. They usually go away in 7 to 10 days. Rinse your mouth several times a day with warm salt water, avoid acidic food and drink, don't apply anything to the ulcer. Your dentist might be able to treat it with a soft tissue laser or chemical cauterization.

Canker = Aphthous : Researchers are not sure of the cause of aphthous ulcers. There is no known preventive measure. Treatment is palliative with low level laser therapy able to relieve pain & accelerate healing with about 5 minutes of treatment. Biolase waterlase works well of lasers I have tried. Herpes is another possible ulcer. Oral cancer can also be an ulcer. See your dentist to find the right diagnosis.

Topical cream: Typical ulcerations can be treated with oral creams such as orabase that will treat the symptoms until it resolves. Laser dentists, such as myself, typically use the waterlase laser to treat the ulcer which speeds up the healing time.

See your dentist: There are many various reasons which could cause a mouth ulcer (e.g. canker sore, pemphigus, etc.). I can appreciate your concerned about your dental health, but finding a proper diagnosis and treatment may be the answer to your problem. Rec.: see your dentist for examination and treatment if needed.

Have patience: Mouth ulcers generally heal in seven to ten days. I would not recommend putting anything on it as that can burn and cause additional healing time.
