@giacaman97 The metals in dental work and implants do conduct electricity in the mouth and when there are different metals present, it can act as a battery with the saliva. Batteries work by conducting electricity between 2 different metals ( the positive and negative poles) in a fluid. Metals can also trigger immune responses in some people. I know someone who had to had titanium dental implants removed after 9 months because of an immune response that wasn't under control and the patient was taking prednisone long term to try to control it. After her implants were replaced with ceramic implants, she was fine and healed. I have a biological dentist who's concern is bio-compatibility of materials used in dental restorations. I have had all my old silver amalgam fillings removed and replaced. I also had some old root canals that were going bad and I had those teeth extracted in preparation for dental implants. The gutta percha used to fill a root canal contains cadmium, a heavy metal, and while those teeth with the metals of the crowns were in my mouth, I had a lot of breathing issues an excess phlegm that easily lead to chest infections. I have asthma, so that is a problem. My breathing got a lot better after removing the bad teeth, so the inflammation they caused definitely affected me. I have had problems with metal allergies, and will be getting dental implants with no metals in them. They are made of ceramic and are bio-compatible. The first question you might want to ask is if there is an immune reaction to the implant in the patient.

A lab in Chicago does blood testing for this. See https://www.orthopedicanalysis.com/

The patient may want to seek another opinion with a biological dentist. If there is a problem now, just a month after the implant was placed, it is probably much easier to remove now because bone growth around it may not be complete yet. The other patient I spoke of having titanium implants removed after 9 months required the doctor to break the jaw to get them out. I have bone grafts in my jaw that need to heal for 5 months before I can have ceramic implants placed. There can also be other physical issues with neck, spine and jaw alignment that can contribute to facial pain. The ceramic implants I am getting are Zeramex and bone will actually grow into them. There is no metal. Here are several links for information.

The Environmental Health center in Dallas does have treatments for sensitivities to dental materials, so they could be a source of information as well. https://www.ehcd.com/dentistry-and-chemical-sensitivities/
