Health Tip: When a Canker Sore Emerges

(HealthDay News) -- Canker sores are painful ulcers that form inside the mouth. While they'll usually heal on their own, they can be very uncomfortable.

The Nemours Foundation suggests how to cope with a canker sore:

  • Take an over-the-counter pain reliever.
  • Avoid foods that are spicy or acidic, such as lemons or tomatoes.
  • Stay away from crunchy foods that may scratch the sore, such as potato chips or pretzels.
  • Avoid the sore when brushing your teeth, and use toothpaste that does not contain sodium lauryl sulfate.
