Michael, I needed a root canal earlier this year -- My fairly young dentist and I both checked around and since a root canal only deals with the tooth and tissue (Ream it, clean it, pack it and back-fill), we found it to be OK.

Pulling the tooth would be a different story, I'm sure.

I'm still mostly doing liquids (in part because I still have six cases of Nutren 2.0, 500 cal/can and I'm waaay too frugal to get rid of them except down the gullet [and recycle the cans]) and also because I'm not yet adept at moving solids around my mouth to chew them. Also, I lost a lot of those taste buds that partially came back when they removed my tongue front. So that means I am getting all my vitamins without taking supplements.

Hey, be sure not to take the antacids less than a half-hour after or an hour or so before the synthroid (aka Levoxyl) because the calcium will destroy it.
