How long do dental implants last?

Considering that they are a permanent fixture in the mouth, dental implants generally speaking are designed to last a lifetime as they fuse to the jaw bone. Implant crowns (the head of the implant, not the screw) may require replacement down the line. 

However, it is possible for the implant screw to fail in the months or years after it is placed, and there are several factors which may contribute to this such as;

- Insufficient care/maintenance

- Insufficient bone

- Smoking

- Teeth grinding

- Certain medical conditions

- Age

- Medications/medical treatments
