Canker sores

 

Definition


Canker sores are small white or yellowish sores or ulcers that develop inside the mouth. They are painful, self-healing, and can recur.

Description


Canker sores occur on the inside of the mouth, usually on the inside of the lips, cheeks, and/or soft palate. They also can occur on the tongue and in the throat. Often, several canker sores will appear at the same time and may be grouped in clusters. Canker sores appear as a whitish, round area with a red border. The sores are painful and sensitive to touch. The average canker sore is about .25 inch (60 mm) in diameter, although they can occasionally be larger. Canker sores are not infectious.
Approximately 20% of Americans experience recurring canker sores. They are more common in women than in men. Women are more likely to have canker sores at certain times during their menstrual period, suggesting that they may be influenced by female hormones.
Canker sores are sometimes confused with cold sores. Cold sores are caused by herpes simplex virus. This disease, also known as oral herpes or fever blisters, can occur anywhere on the body. Most commonly, herpes infection occurs on the outside of the lips and the gums, and much less frequently on the inside the mouth. Unlike canker sores, cold sores are infectious.

Causes and symptoms


The exact cause of canker sores is uncertain, however, they seem to be related to a localized immune reaction. Other proposed causes for this disease are trauma to the affected areas from toothbrush scrapes or dental cleanings, stress, hormones, and food allergies. They may also be related to nutritional deficiencies.
Canker sores commonly tend to appear in response to stress. The initial symptom is a tingling or mildly painful, itching sensation in the area where the sore will appear. After one to three days, a small red swelling appears. The sore is round and whitish in color with a grayish colored center. Usually, there is a red ring of inflammation surrounding the sore. The main symptom is pain. Canker sores can be very painful, especially if the tongue touches them repeatedly. They last for one to two weeks and heal on their own.

Diagnosis


Canker sores are diagnosed by observation of the blister. A distinction between canker sores and cold sores must be made because cold sores are infectious, and herpes infection can be transmitted to other people. The two sores can usually be distinguished visually, and there are specific diagnostic tests for herpes infection.

Treatment


Since canker sores heal by themselves, treatment is not usually necessary. Pain relief remedies, such as over-the-counter topical anesthetics, may be used to reduce the pain of the sores. The use of corticosteroid ointments sometimes speeds healing. Avoidance of spicy or acidic foods can help reduce the pain associated with canker sores.

Alternative treatment


Alternative therapies for canker sores are aimed at healing existing sores and preventing their recurrence. Several herbal remedies, including calendula (Calendula officinalis), myrrh (Commiphora molmol), and goldenseal (Hydrastis canadensis), may be helpful in the treatment of existing sores. Compresses soaked in teas made from these herbs are applied directly to the sores. The tannic acid in a tea bag can also help dry up the sores when the wet tea bag is used as a compress. Taking dandelion (Taraxacum officinale) tea or capsules may help heal sores and prevent future outbreaks. Since canker sores are often brought on by stress, such stress-relieving techniques as meditation, guided imagery, and certain acupressure exercises may help prevent canker sores or lessen their severity.

Prognosis


There is no cure for canker sores. They do not get larger or occur more frequently with age.
