Thanks all for the excellent references and information on this subject. They reinforce and add to my opinions about this… At this point only one question remains for me personally.
Assuming amalgam is a technically sound, safe, and best solution, why did 6 of these 8 dentists suggest the weaker substance for initial fillings now? They weren’t advocating replacing amalgam, just not using it for new fillings. They were randomly sampled doctors of dental science. I suggested he make these calls when he first told me his(and his mother’s) concerns. I was very surprised at the results.
Not being willing to say why could lead a fearful person to speculate that these dentists fear legal reprisals for previous work they did. (lmao)
Several plausible motives occur to me:
the environmental concerns about using mercury for anything(hard to put in perspective but I care alot about environmental concerns also), unlikely motive imo
fear of patient reprisals(even unfounded accusations can be damaging and costly), a little more likely
consession to public opinion. they may be “going with the flow”
using the weaker material creates more repeat business.
Reading motives is a tricky business, imo, (unless you are on the PTA :). I realize a sample of 8 dentists is less than overwhelming, but I wish some dentist who is doing this would offer their explanation(possibly under the cover of anonymity if necessary).
The technical arguments seem very overwhelming, but it’s still amazing to me that my son could not extract an explanation out of any of the 6 dentists that don’t use amalgam anymore(unless asked to, I assume).
So, for me, a mystery remains. My son’s dentist is planning to redo 3 fillings with composite, at no additional cost(a very considerate gester, I think). Like 2 of my coworkers, his mouth will be “metal free”.
His right to decide for himself, I think, exceeds this issue(he’s 19 today), but I would love to find a way to persuade him before he does this. With all I have seen, his survey does still seem to me to be logical grounds for apprehension.
Again, many thanks to all.
