Growing up, my younger sister was always getting those annoying little canker sores in her mouth. She would always use this Orajel Mouth Sore Medicine to get rid of them quickly. Now, whenever I accidentally bite the inside of my mouth, I pull out this gel and use it for myself. It works great. The canker sores always seem to go away quicker and less painfully than when I just wait for them to go away on their own. The taste isn't great, which is why I gave it a nine, however. But, this is no reason why you should not buy this product. The taste can be easily overlooked when you are trying to get rid of a nasty, painful canker sore in your mouth. I always have this product on hand, because I never know when I'll get another canker. I plan to use this with my children too, because as another poster mentioned, when/if they get braces, this will be a great relief if they get sores from them. Great product!
