Getting Rid of Canker Sores

Canker sores often pop up when you are feeling stressed. Unfortunately, canker sores can cause even greater stress. Canker sores may also be the result of vitamin deficiencies in the blood. To treat canker sores at home, rinse your mouth with hydrogen peroxide or warm salt water. This will reduce inflammation and sooth discomfort. You can also purchase an over-the-counter antiseptic gel to numb the gum tissue around the canker sore so you can eat and talk without pain for up to 45 minutes at a time.

Watch this video for more advice on treating canker sores at home. If canker sores are a recurring problem, then contact Dr. Charles M. Marks or any of his skilled dental associates. Dr. Marks is proud to be one of the leading dentists in Manhattan, and he can help sooth all of your dental problems.
