Wellboy,
You may want to check out the CureZone Amalgam site before you get your titamiun bolt. Seems to be a lot of reasons to not have any metal in your mouth or jaw. With that said, I have a root canal and crown, that give me no problems, that I would hate to have extracted. I also have a mouth full of silver that I plan to slowly replace $$$$. I am feeling very excited about oil pulling, it seems to be helping me keep my teeth cleaner and my gums healthier. I would hate to give it up just because a chunk of old Amalgam fell off day three of oil pulling. Good luck with the permanent crown.
