Consider this: There are several over the counter medications developed to control canker sores. For those who prefer not to medicate you may try hene laser. The spot should be on the lesion for 30 seconds and cover the adjacent tissue. For more info: http://www.Webmd.Com/oral-health/guide/canker-sores.

Canker sore cocktail: Rinse for 10 seconds with an equal mixture of maalox stomach medicine, liquid benadryl, (diphenhydramine) and chloroseptic sore throat medicine. Then rub orajel on the sore. Next place a small amount of salt on your finger and hold it against the sore for ten seconds. Repeat 3-4 times a day. If you are prone to canker sores, your dentist or doctor can prescribe an anti-viral.

Keep it simple: Mostly time. There are some medications or ointments you can get in a pharmacy to help them feel better meanwhile. Ask your pharmacy what they have and what they recommend. Some dentists can apply in-office treatment or laser to speed recovery somewhat.

A topical ointment with benzocaine will numb the area for a while. It will heal but it takes 10-14 days. It should begin to feel better in 5-6 days

Canker Sores: Pain from a canker sore generally lessens in a few days and the sores usually heal without treatment in about a week or two. If sores are large, painful, or persistent, your dentist may prescribe an antimicrobial mouth rinse, a corticosteroid ointment, or a prescription or nonprescription solution to reduce the pain and irritation.

Isolated mouth sore: Cankers are isolated shallow ulcers on the inside of the lip, lining of the cheeks or on the tongue. They hurt even though they're no more than 2-3 millimeters in diameter. No fever. You can't help run your tongue over it - that probably inhibits healing. Multiple ulcers on the lip think herpes type 1. Multiple sores in back of mouth with fever think herpangina or hand-foot-mouth syndrome.

Canker Sores: Generally, canker sores are painful and have a white crater in the center surrounded by a rim of bright red inflammation. They usually go away after a few days, but there are ways to treat them with topical cortisone or an injection or cortisone that will make them resolve much faster. See you dermatologist for help.
