Why Do Dental Implants Fail?
Though rare, dental implants can fail under several circumstances, including:
- Failed osseointegration: When implants do not fuse properly with the surrounding bone, they can weaken or fall out altogether. Without a strong, sturdy foundation, implants cannot support a crown, bridge, or denture.
- Peri-implantitis: This type of infection forms in the tissue around the implant and leads to bone loss and implant exposure.
- Mechanical failure: In rare cases, the implant post or abutment can break. This issue is generally due to poor initial planning.
If you begin to experience swelling, inflammation, or pain around your dental implants or notice your implant becoming loose, you should contact your dentist right away as these are signs of implant failure.
While implant-supported restorations are more stable and secure than traditional options, they are not designed to last forever. They are subjected to daily wear and tear, which can affect their function. You may need to replace your restoration if you notice:
- Significant changes in the fit of the restoration
- Chips or fractures in the dental porcelain
- A loose restoration
- Excessive wear on the surface of the restoration
In most cases, implant-supported restoration can be replaced without surgery. Your dentist can fabricate a new crown, bridge, or denture and reattach it to the underlying abutment. If your restoration fails, contact your dentist immediately. Leaving a missing or damaged restoration untreated can cause more substantial oral health concerns.
If the post or abutment piece is damaged, it is important to consult your dentist as soon as possible to discuss replacement. Removing and replacing a failing implant can protect your oral health and preserve your smile.
Dental Implant Failure
Dental implants have one of the highest long-term success rates of any tooth replacement option, at about 95 percent. However, dental implants can fail if they do not fully fuse with surrounding bone, or if you develop an infection that compromises neighboring tissue.
