Wow! Thanks for everyone's help I couldn't believe how many replies I got!
Yes, I started to do the salt loading (I am new to all this) and I noticed it did help with the swelling in my face. So thanks for the advice! I am not taking any of the companion nutrients, thank you for mentioning those, I had never heard of them before but I just looked them up online and I will go and buy those. I am reading the book Iodine Why You Need It Why You Cant Live Without It by David Brownstein and I just saw it goes into those nutrients in the later chapters. I'm only halfway through so far. Great book though!
Portlander thank you, that gives me somewhere to start researching about that as a possible cause. I have a lot to learn I guess!
I do have one cap (but not a root canal!) I had no idea that they eventually need a root canal? Its only a year old and I haven't experienced any pain so far, I got it done at a holistic dentist and they did say it might need a root canal but they didn't say how far in the future, they just say basically we'll wait and see and if there's no pain then the cap should be fine. Its porcelain (no metal) and I read that the porcelain is supposed to be really strong? Did you have pain when the cap started to go bad, is that how you can tell?
Thanks for everyone's help! Going to order companion nutrients now...
