Can Dental Implants Fail?

can-dental-implants-failOne common question is “Can your body reject a dental implant?” While dental implant failures are rare, they do happen, but they’re not at all caused by the body’s rejection of the implant. A dental implant, unlike a transplant, does not create antibody or antigen type responses within the body, so there is no trigger that tells the body to reject the foreign object. Instead of rejection, the body adapts and fuses to the dental implant in most cases, although dental implant procedure failure can happen. What causes dental implant failures? Well, there are a number of factors that go into just why dental implants may fail.

There are two different types of dental implant procedure failures – early failure and late failure. Early failure is a common type of failure, and while still rare, occurs when the dental implant is unable to make the fusion into the jawbone. When the implant fails to fuse into the jawbone, it never creates that necessary solid anchor required for a crown in place of a missing tooth root. Typically, these failures are caused by a lack of bone density or problems that can be detected before the implant is placed, and will often be caught and rectified before the dental implant procedure by a dentist.

Late failure is more common than early failure but is still very rare. Ten-year success rates of dental implants are over 95%, and it’s this 5% who experience late dental implant failure due to a variety of factors. Late failure occurs when the initial dental implant procedure is successful, but over time the dental implant is lost due to bone loss around the implant or some type of injury. The most common reason this bone loss may occur is due to infection eating away at the bone, and infection is best prevented by carrying out diligent daily oral hygiene.

While dental implants can fail, their failure is not due to a body’s rejection of the implant. The best way to keep your dental implant for the long haul is to seek out a dentist you can trust and ensure all of the proper prep has been carried out before your dental implant procedure. To avoid late failure, make sure to take good care of the implant all throughout the years.
