What Causes Metalic Taste In Mouth After Getting Root Canal Treatment?

Hi, about 5 years ago I had a root canal on a molar and then a gold crown. I later found that my xray shows 3 to 4 broken small rotary files broken inside my root but also, one of the broken tools was deep down in my lower gum below the root (??). After the gold crown was installed, I have had a metallic taste on the same crown and I have even had a dentist ask me if I had a gold allergy. She said that I had problems around the tooth, on the gums, that looked like an allergic reaction and the gums had turned a white color.
I really can't handle this much longer. My tongue is now very sensitive and has a bump near the
gold crown. I have been through H... with several dentist and have gotten different opinions from each.
Thanks, Danny

Thanks for your query, I have gone through your query.
The metallic taste can be secondary to the drugs or medications taken for tooth infection particularly metronidazole. The other possible cause can be because of persistent tooth infection resulting inn pus discharge. The white color over the gums can be because of the lichenoid reaction or allergic reaction to the metal crown. Nothing to be panic, consult a oral physician and get the infection treated. Once the antibiotics are stopped, the metallic taste will come down. You have to get the crown replaced with ceramic crown.
I hope my answer will help you, take care.
