Any surgical procedure has risks.
The most common is if the dental implant fails to “integrate” into the bone and is lost.
Common factors that affect this are smoking, diabetes, and poor at-home care. The second most common problem is called peri-implantitis, which is an infection around the dental implant, leading to possible loss of bone, or loss of the implant itself.
In the significant majority of cases, however, implants can last for many years, with nothing more than routine maintenance both at home and at regular dental visits.
