Bryanna is spot on. I removed several teeth rather than additonal treatment that in the long run does not work. Saving an infected tooth, puts your whole immune system on guard, and is not the best option in my opinion. I have immune problems to begin with, and sure didn't want additional problems. I wound up with a simple device called a besnit. You may want to look into this. For me, it was a wonderful solution to an awful problem I wish you all the best. ginnie
