An aphthous ulcer also known as a canker sore, presents as a painful open sore inside the mouth. Canker sores do not appear to be caused by viruses or bacteria, although an allergy to a type of bacterium commonly found in the mouth may trigger them in some people. The sores may be an allergic reaction to certain foods. Aphthous ulcers can affect people of any age.
Emotional stress and local trauma or injury to the mouth, such as sharp metal braces, brushing with hard toothbrushes, citrus fruits and hot foods can lead to canker sores. Smoking and dentures can also contribute to the problem. Other possible causes of canker sores include illnesses in which the immune system causes swelling or from autoimmune disorders. Female sex hormones also apparently play a role in causing canker sores.
Laser Therapy Treatment - Laser Therapy is the most effective, giving immediate pain relief and causing the ulcer to heal in 24-72 hours. Pain relief is immediate and lasting. The ulcers heal in two to four days.
Prevention-
Avoiding known triggers.
A healthy diet with vitamin supplementation is recommended.
Excellent oral hygiene, including use of antibacterial rinses (Rx chlorhexidine or OTC Listerine), has been shown to reduce frequency of attacks.
Reducing stress is important as well.
