Health Tip: Calm a Canker SoreLast Updated: March 13, 2012.
(HealthDay News) -- Canker sores are ulcers that form inside the mouth that can make eating and drinking painful.
The American Dental Association suggests how to help heal a canker sore:
- Apply an over-the-counter topical anesthetic to numb the sore.
- Use an antimicrobial mouth rinse.
- Avoid foods that may irritate the sore, especially anything spicy, hot or acidic.
- See your dentist if the sore doesn't heal without treatment after two weeks.
- Use an antibiotic and/or bandage as recommended by your dentist, to help reduce the risk of infection.
