What Causes Mouth Sores?

Irritation From Braces Or Retainers

An individual who develops frequent mouth sores may also be experiencing irritation from orthodontic equipment like braces, retainers, or other appliances installed in the mouth and around the teeth. When it comes to orthodontic equipment and appliances in the mouth, an increase in the amount of friction on the gums and other tissues can trigger the development of ulcers. The inside of the lips and cheeks are tough to a certain degree, but sometimes the sharp, pointy, and metal-containing components of an individual's braces, retainer, or other orthodontic appliance are enough to puncture the outer layer of these tissues. Mouth sores are especially common among individuals who have just gotten their braces, retainer, or other orthodontic appliance installed on their teeth or in their mouth, as the sides of the mouth and the lips are not acclimated to the presence of these objects. Most individuals get mouth sores less and less throughout their orthodontic treatment, and may only experience the occasional sore when they have their braces changed out or adjusted.
