Looking For Amalgam/Root Canal Removing/Replacement Dentists in NY
State
I’m looking for dentists who will remove my amalgam fillings and root
canals and replace them with composites.
Are there any directories for such dentists?
I am specifally looking for such dentists in the Mid-Hudson Valley NY
area.
Also what can I expect to pay for such a procedure? on a per filling
basis, on a per visit basis?
Also is their any dental insurance or plan that now accomodates
amalgam filling and root canal removal and replacement.
All the best,
Tony
