According to a 2016 study on dental implants and diabetes, researchers found that “When diabetes is under well control, implant procedures are safe and predictable with a complication rate similar to that of healthy patients.” People with poorly controlled diabetes are at greater risk for dental problems. They're more likely to have infections of their gums and the bones that hold their teeth in place because diabetes can reduce the blood supply to the gums. High blood sugar may also cause dry mouth and make gum disease worse.
Also, in patients with diabetes – age may matter more than usual. This is because the longer you’ve had diabetes, the more prone you are to infections and slower healing processes. If you have diabetes and are interested in getting dental implants, sooner is definitely better than later in most cases.
