As dental implants are designed to integrate with your jawbone, they are meant as a permanent tooth replacement solution. With proper care, the implant screw can remain strong and healthy for 25 years or longer. For some, implants last a lifetime.   That said, you may need to replace the crown, bridge, or abutment every five to ten years or so. The implant goes through a process of osseointegration, which means that it becomes a part of your jawbone. This process contributes to its longevity. The crown, bridge, and abutment, on the other hand, remain separate from your natural tooth structure. As such, they have less longevity. Still, replacing the crown, bridge, or abutment will be a significantly less invasive procedure, as the implant installation is already done.
