In brief: Canker sores

The canker sore should run a course in about 7-10 days.
They can be very sensitive. Visit the drug store, they have a few over the counter ointments you can apply throughout the day to numb it? Stress, spicy foods, cinnamon products, some toothpastes with sls and a surfactant, vitamin deficiencies can cause canker sores in sensitive mouths. Discuss with yor dentist.

In brief: Prevention not easy

It is difficult to prevent the canker sores because most of the time they are caused by an exaggerated immune response to a food or other product placed in your mouth like mouthwash or tooth paste.
If you can figure out what things trigger the sores then you are on your way to prevent them. The sores usually resolve in a week or so and all you can really do is ease the pain with otc meds.
