I used to get tooth aches really bad and the only thing that would stop the pain was Colloidal Silver . I would have to hold it in my mouth for a long time and keep doing that. I had two abcessed teeth ("12 year old molers") and we didn't have money to get them pulled, so my Dad got me an irrigator, and I would irrigate my mouth every day. It really help, and stopped the infection, but it did turn my teeth a slight grey, which was temporary. I finally had the two teeth pulled and have not had trouble since, but I was really glad to have the irrigator and Colliodal Silver, ans I believe that is what really stopped the infection!
