I haven't had the problem, but other folks on the oil pulling forum have. I know the oil pulling sounds really weird, but it works. It can't hurt you to give it a try. I'm sure you have oil in your kitchen cupboard (you can use any oil, not just those I've mentioned). The oil removes bacteria, viruses, fungi/yeast, heavy metals, etc. It rids you of plaque and tartar. All sorts of good stuff!
