What can you do to get relief from canker sores?

ANSWER

To ease irritation, don't eat spicy, hot foods, or anything with a high acid content, such as tomatoes or citrus fruits. Most canker sores disappear in a week to 10 days.

For relief, try over-the-counter "numbing" medicine that you put directly on the sore. If you get canker sores often, your dentist may prescribe a steroid ointment.
