Sore Mouth – Learn More

Canker sores (better known as aphthous ulcers) are one of the most common oral conditions affecting people everywhere. Up to 25 percent of the population has these small, painful, persistent sores, with recurrence rates of up to 50 percent.

Canker sores appear on the tongue, soft palate, insides of the cheeks or lips and base of the gums. While they have the benefit of not usually being visible, they are likely to make eating, swallowing and speaking painful.

Cause of Canker Sores

Canker sores are not viral or infectious. They may be hereditary since 30 to 40 percent of those with recurrent canker sores have a family history of the condition. According to research reported by the National Institute of Dental and Craniofacial Research, “Canker sores may be caused by a faulty immune system that uses the body’s defenses against disease to attack and destroy the normal cells of the mouth or tongue.”

Simply stated, their cause is unknown; however, common canker sore triggers may include:

• Stress.
• Immune deficiencies.
• Illness or infection.
• Gastrointestinal disease.
• Tissue manipulation — including prophylactic dental and gum cleanings and overzealous tooth-brushing.
• Tissue injury — for example, biting the inside of the mouth.
• Eating abrasive foods (such as potato chips, dry cereals and dried fruits), acidic foods (such as vinegar) and spicy foods (curries, chilis and hot sauces).
• Food or contact allergies.
• Although not yet proven, nutritional deficiencies — particularly a lack of vitamin B-12, folic acid or iron — may also play a role.

Canker Sore Diagnosis

If you suspect you have canker sores, you may wish to consult with your dentist first to rule out a more serious type of mouth sore. Dentists specializing in oral health conditions are in a better position than physicians when it comes to diagnosing and managing these sores — and particularly at distinguishing them from intraoral herpes, a contagious viral condition which may lead to serious problems in people with an impaired immune system.
