In the clinic, we often meet patients who ask: Are dental implants guaranteed to last a lifetime? To answer this question, it can be explained that dental implants are equivalent to real teeth in terms of form and function, but it depends on the patient’s use and maintenance. Generally speaking, the life span of dental implants is equal to that of real teeth. In other words, if the surrounding natural teeth are always present and well used, the dental implant will not be a problem. On the other hand, if the surrounding natural teeth have periodontitis, bone resorption, external impact, etc. can affect the dental implants. Therefore, it is not possible to say that dental implants will last a lifetime. However, dental implants are the best restoration method available.
