Can a Single Implant Fail and What Happens Then?
While implants have a high success rate, failure can happen. Here is what you need to know.
Yes, dental implants can fail, but it is uncommon. Failure occurs in about 2β5% of cases.
Types of implant failure:
- Early failure (within the first few months):
- The implant does not bond with the bone (osseointegration fails)
- Causes: infection, insufficient bone, smoking, overheating the bone during surgery, or the patient putting too much pressure on the implant too soon
- Usually detected within 2β4 months
- Late failure (after the implant has been in use):
- The implant fails after being in function for years
- Causes: peri-implantitis (gum infection around the implant), excessive biting forces, grinding teeth, or trauma
- Can occur 5, 10, or even 20 years after placement
- What happens if an implant fails:
- The implant is removed β usually a straightforward procedure
- The site is allowed to heal for 2β4 months
- A bone graft may be placed to rebuild the area
- A new implant can often be placed after healing
- Maintain excellent oral hygiene
- Do not smoke
- Attend regular checkups
- Wear a night guard if you grind your teeth
- Treat any gum problems early
Can a Failed Implant Be Replaced?
Yes β in most cases, a failed implant can be removed and replaced with a new, larger implant after the area has healed. The success rate for replacement implants is still good, though slightly lower than the first attempt.
