Canker sores are small ulcers found on the interior surfaces of the mouth. They are round or oval-shaped and may have a whitish or yellowish coloring. Ulcers may appear spontaneously or as a result of injury to the mouth. Most ulcers heal within seven days with no treatment. However canker sores can be extremely painful. Remedies are available to help aid in healing and ease the pain.
Mouth Rinse
The Mayo Clinic recommends a mouth rinse to cleanse and alleviate the soreness associated with canker sores. Home remedies include a saltwater rinse; a rinse of 1 tsp. baking soda in 1/2 cup of warm water; and a rinse of 1 part hydrogen peroxide to 1 part water. Do not swallow these rinses. Spit them out after use.
Baking Soda Paste
Lesions can be covered with a paste of baking soda and water. This relieves the pain of the ulcer.
Numbing Gels
Available over the counter, apply the topical gel directly to the ulcer as the directions indicate. This relieves the pain caused by the canker sore, at least temporarily. When an ulcer impacts a person's ability to eat or speak, numbing remedies make these activities more tolerable.
Ice
Apply an ice chip directly to the ulcer. Allow the ice to melt slowly on top of the ulcer. This washes and numbs the ulcer.
Milk of Magnesia
The National Institutes of Health recommends a mixture of 1 part Benadryl and 1 part Milk of Magnesia. Rinse the mouth and spit out. This soothes the ulcer and reduces discomfort.
