3 words.......WARM SALT WATER!!!! I know its nasty but it works so well. I have a genetic gum disease that causes my teeth to become really weak. They break and chip like crazy, if its not fixed it decays and the nerve dies. Salt water is my best friend. Just yesterday one of my biggest problem tooths that i need a root canal on decided to flare up again. Started swelling and getting down right painful. swished warm salt water and within an hr the pain left and the swelling went down.
This doesn't always work at first but you need to rinse with Salt water at least once an hr and you'll start feeling the difference. My dentist keeps me supplied with pain killers. If you cant find relief in salt water, call your dentist and let them know the pain you are in. they can call you in a pain killer perscription since they already know of the issue.
