What kind of topical medications (gels or ointments) are available for canker sores?

Topical gels or ointments are used for canker sores to relieve pain, decrease inflammation, and prevent infection.

  • Topical pain medications: Gels such as benzocaine (Oragel) and lidocaine (an anesthetic) are used directly on the canker sore to relieve pain or discomfort. These types of medications can be found over-the-counter.
  • Topical anti-inflammatories: Steroid medications can be used topically to decrease inflammation from canker sores. These medications usually require a prescription and should be used exactly as directed.
  • Topical antibiotics: These medications may be prescribed by your doctor or dentist if there is a possibility of the canker sore becoming infected with bacteria. Redness, crusting, pus discharge, or fever, are signs of infection.

Eat one or two granny smith apples. Hold the pulp of the apple when it's in your mouth against the painful part of where the sore is (mine is always on the edges of the tongue). It almost instantly takes away the pain. Eat the apple when the pain just starts.

My daughter had a couple of canker sores and we used custard powder to heal it. In two days it was gone. I tried straight baking soda, which burned her too much, but she loved the custard powder. It worked to heal and soothe the pain.
