Hi terric,
Sorry to hear of your problems. Dental implants are made from titanium and although allergies to this metal are very rare they are not unknown. A MELISA test should be able to detect if an allergy is causing the problem.
It is probably also worth visiting to your dentist to check the health of your dental implants, just in case there is another reason as to why you are experiencing these side effects.
If it is an allergy to titanium, then it is possible to have metal-free implants that are made from a strong ceramic material called zirconia.
Best regards,
Ali
