Canker sores are common while wearing braces. Cankers are sores that develop on the gums or inside the cheeks, sometimes developing against the bracket. It is thought that they develop because of bacteria or other organisms that irritate the tissue and form a sore. They can be treated with mouthwashes or medicine that numbs the pain for short period of time. You can also put wax on your brackets to lessen the irritation of the inside of your mouth. This might be able to prevent canker sores and is a way to relieve pain from them, too. If you have continued problem with canker sores while wearing braces, talk to your orthodontist.

A common cause of canker sores is braces. Loose orthodontic wire can irritate the mouth. These typically go away within a week.
Over-the-counter topical anesthetics and antimicrobial mouthwashes may provide temporary relief. Stay away from hot, spicy or acidic foods that can irritate the sore. Antibiotics from your dentist and some oral bandages can reduce secondary infection.
Greg Jorgensen, DMD, Dentistry, answeredCanker sores unfortuneately occur whether or not you have braces. For some braces, just the "shock" of having something new in their mouth causes them to have an episode. Here are some ideas for making yourself more comfortable if you get one during treatment. If part of the braces is actually poking you and causing the problem, either you or your orthodontist needs to tuck or adjust whatever is cause the irritation. Place orthodontic wax over the offending part until you can see your doctor. Once you have a sore, all of the treatments are just to make things feel better. Oragel, Brace Relief, and other similar products have numbing agents that will help you feel more comfortable. These can be purchased over the counter at any discount or drug store. There are also all kinds of canker sore remedies that may help and you'll have to experiment to see if one if helpful for you. Good luck!
