It sounds like you have already found yourself a good dentist. I wish you well. Remember that the poison from your teeth that was deposited in your body's tissues must be chelated out in addition to your dental work. Oral or Intravenous both seem to work well. Paul...
Since this forum is an open medium, I'd like to expound on the subject of a good dentist for our other readers.
From my own experiences, it appears they each follow their own preferences in the performance of their skills. Accordingly, I'd suggest that you not get overly concerned with such differences, but by all means, you should understand and discuss all procedures prior to their commmencement. Also, a good dentist won't accept you as a new patient without your compatability test. However, if you are like most people, then you probably never had such a test. That alone is proof positive that your dentist was below par.
Since your body will be sensitive to any foreign material placed in your mouth, it is necessary to determine what your body tolerates, and what your body wastes much of its resources trying to fight. If a dentist tells you he has something inert that he can use on everyone, find another dentist. The only thing inert is your own flesh and blood. Everything else is foreign to your body. A good dentist will use what's least offensive to you as per your actual responses revealed on a test.
One of the better labs has a web site I suggest you check out. However, the choice of lab will depend on your dentist and which materials he uses.
I'm sorry I can't give you the address at this time, since I forgot to lQQk it up. I will try to post it below this post at a later date.
