| They are painful, small ulcers in the mouth or on the inner lips caused by an assortment of viruses. Doctors call this condition aphthous stomatitis, aphthous ulcers or canker sores. They can appear on the tongue, the lips, the gums or the insides of the cheeks. Causes & Development; Risk Factors The exact cause of these tiny but quite painful mouth ulcers is unclear, but most research indicates that a virus is responsible. Canker sores do not form blisters as cold sores (fever blisters) do. The canker sore, on the other hand, is an inflammation rather than an infection. A susceptibility to canker sores tends to run in families. Signs & Symptoms The first sign of a canker sore may be a tingling, burning sensation inside the mouth, followed shortly by the appearance of a white or yellowish spot edged by a red halo. Canker sores may range in size from the size of a pinhead to as large as a quarter. The natural remedies may help relieve the symptoms of canker sores or may prevent sores from recurring. Prognosis They appear suddenly and often leave suddenly, usually lasting from four to twenty days. |
