Canker sores, not to be mixed up with cold sores (which is a common misconception), are small white ulcers that develop on the inside of the mouth on the tongue, lips, gums, or the inside of the cheeks. Unlike cold sores, which are caused by the herpes simplex virus type 1, a canker sore is actually an inflammation. The most common cause of such sores is stress and allergies. It can also occur as a result of over acidity, poor dental hygiene, vitamin/mineral deficiencies, an immune response to bacteria in the mouth, mistakenly biting one’s own cheek, and irritations from dental work. Frequent sores have also been associated with Crohn’s disease.
The sores can last anywhere from 4-25 days, thus, following some suggested guidelines may shrink the length of their unwelcomed visit. In terms of supplements, it is a good idea to take high quality Acidophilus. Vitamin C which fights infections and boosts the immunity is also suggested. Herbal formulas containing capsicum, alfalfa, calendula, comfrey, peppermint and garlic can also speed up healing time. The homeopathic remedies Borax, Echinacea, and Belladonna have also been helpful in eliminating canker sores.
As far as diet goes, you will want to stay away from sugars, coffee, meat, citrus fruits, chewing gum, and processed foods. You should eat plenty of salad and include raw onions in the diet as much as possible. The sulfur found in the onions is excellent for healing. Include plenty of yogurt, cottage cheese, buttermilk, and kefir in your diet as well. It is important to change your tooth brush once a month to reduce the risk of further sores. If you have a sore that does not heal after 25 days, you should consult your doctor.
