Just like you may get sores on your feet from wearing new shoes, you may develop sores in your mouth until you get used to the braces. Don´t worry!! They usually they heal within 3-5 days.
Sores can be prevented by placing orthodontic wax on the area that is bothering you. If sores do happen, there are a variety of products available in pharmacies to treat wounds or sores. The most effective are those that create a protective film over the wound thereby reducing any pain and accelerating healing. Other products available only decrease the discomfort. Rinsing with warm salt wáter significantly reduces the discomfort aswell.
