How To Treat Canker Sores
Ice

Applying ice is yet another easy (and free) way to treat a canker sore. You can use a solid cube, leaving it in your mouth to suck on or break a piece into chips. Either way, you need only to suck on the cube and keep it in your mouth for a few minutes before its anti-inflammatory, soothing effects kick in. While using ice in any form will not make the canker sore disappear, it will allow you to feel better and in less pain. Alternatively, if you don't have access to a freezer, you are welcome to use cold water, which will also work. Just remember to always swish it around in your mouth before spitting it out. The coldness of the solid or liquid slows down blood flow to the area, reducing swelling and pain.
