How to Remove a Canker Sore

Canker sores are small, white ulcers that are present inside the mouth. Sometimes called aphthous ulcers, canker sores typically present as single sores but do occasionally form clusters. Canker sores run their course in four to 14 days but are very painful and can prevent sufferers from eating and participating in other daily activities.

  Apply over-the-counter topical medications such as Orajel to the area, following package directions. If you have never had canker sores before or are unsure what might work best for you, consult your doctor for a recommendation. The right medications will dissipate pain and prevent further damage to the area.

  Add an L-lysine supplement to your diet for the duration of the outbreak. L-lysine is an essential amino acid that promotes tissue health and can speed the healing of canker sores. Some doctors recommend that people who suffer frequent canker sores take 500 mg of L-lysine daily to help control the occurrence of sores.
