Dental implants are a popular choice for replacement teeth because they are stable,        accurate, and comfortable. However, the life expectancy of dental implants is not well known. The average lifespan of a dental implant is around ten years. However, this depends on a variety of factors, including the quality of the implant, how well it is cared for, and whether it is removed or not. If you are considering dental implants as a replacement option for your teeth, talk to your dentist about how long do dental implants last.
