Does Tibetan Medicine have anything relevant to say about mercury amalgam fillings?
Afaik the accepted dental understanding is that mercury amalgam fillings are much better for big fillings on back teeth for example and pose no health risks. So getting white fillings in this case would be a weaker option and could not seal the tooth as well leading to easier decay.
I'm not sure what to make of modern views against using mercury fillings, mercury is obviously toxic but really does anything close to an effective amount get released into the body, or is just having the filling in the mouth going to cause problems?
The clearest advice I've had against metal in the mouth has been with implants and posts as these go into the body more and disrupt chi flow from a TCM perspective.
