Hello, Most dental implants that your dentist offers are made of titanium or titanium alloy because it’s strong and supposedly bio-compatible. However, research has shown that titanium is not a bio-compatible substance and has caused many illnesses in patients who have titanium based medical devices including dental implants. Titanium implants release metal ions twenty-four hours per day, which might subject your mouth (and ultimately your whole body) to allergies, autoimmune diseases, and inflammation. Many people suffered from severe chronic fatigue syndrome, Parkinson like shaking, and depression, which prevented him from going to work. Some people have dramatic improvements to their health once the titanium devices were removed from their mouths. Thus it is better to remove titanium implants. Hope this helps. Please write back for further queries. Wishing you good health.
