It’s an unusual occurrence, but implants can fail. Once a dental implant has integrated with the jawbone and gums, it may seem indestructible. It’s not. Though they can endure much more bite force than natural teeth, implants have limits and can fail under circumstances we can sum up with the word overload. That’s dental-speak for stress on the implant severe enough to cause failure. Overload can cause any or all of the following:
link in the system and is usually the area where material fatigue occurs. The screw may actually loosen. Often, replacing the screw with a new one is all that’s needed.
However, gaining access to the screw may require us to drill a small hole through the crown. In that case, once the screw is replaced, we can fill the hole with a white filling. Typically, it doesn’t show, and there’s no need to replace the crown.
And sometimes, we just don’t know why an implant doesn’t work. It can be the surgical technique used, changes in body chemistry, hormonal changes . . . it could be a thousand things. It doesn’t happen very often, and implants can be replaced. The fact that it didn’t work once doesn’t mean it won’t work in the future.
