If you have an old amalgam filling, first tell your dentist what problems you're experiencing and why you want it replaced.
If your amalgam filling is intact and causing no problems, there is generally no need to remove it. It is considered safe to leave it in place.
Next Steps
If replacement is needed, consider a dental clinic that uses a rubber dam and high-volume suction, or a dental college with an associated hospital and proper mercury-handling facilities.
Health Tips
During removal, proper ventilation, collection of amalgam waste, and safe disposal are important to minimise mercury exposure and protect the environment.
