Không đụng vào vết viêm loét. Xử lý vòng niềng răng. Tránh dùng các sản phẩm chăm sóc răng miệng có chứa sodium lauryl sulfate (SLS). Tránh các thực phẩm chứa nhiều a-xít mạnh. Bỏ qua những thức ăn “nhọn”. Ngừng dùng các loại thuốc lá.

You are probably hyper aware of your canker sore. Every time you open your mouth, your teeth brush past your open wound, irritating it further and sending waves of pain throughout your body. Do your best to avoid further irritating your canker sore. Chew your food on the other side of your mouth, far away from your sore. Do your best to keep your tongue away from it. Don’t pick at it. Don’t squeeze it. Just leave it alone and let your body heal. If you have braces, you probably get canker sores
