[YEA] I have found that grapefruit seed extract kills the infection and takes away pain. After trying many home remedies including cloves and vanilla extract (which helped quickly, but didn't last), I decided to try grapefruit seed extract. I put three drops in about 1/3 cup warm water and swished for about a minute. The pain usually goes away quickly. After a few days of swishing a few times a day, the pain was gone and didn't come back for over a month. Now, I use GSE anytime I have a toothache, and it's gone within a day. I'm trying to avoid a root canal. I also need to change my bad sugar habit and eat healthier to really heal the problem.
