The most common cause of mouth ulcers is trauma from inadvertent bites, burns or tooth brushing. Dentures and orthodontic appliances may also cause ulceration particularly when first fitted.
Some individuals suffer from recurrent oral ulceration (aphthous) and occasionally multiple ulcers may be caused by the Herpes virus.
Dentures or orthodontic appliances should be adjusted by the dentist who fitted them.
The condition will be helped by using an antibacterial mouth rinse such as Chlo-hexidine Gluconate twice daily for one minute. Bonjela gel also helps. Ulcers normally heal within a week or so. If they persist for more than four weeks you should consult a dentist.
Mouth ulcers are usually round or oval sores that commonly appear inside the mouth. In all instances the ulcers are painful when eating. Spicy and acidic foods are best avoided.
