Dental implants are designed to be a long-term solution for tooth replacement, and with proper care, they can last a lifetime. Factors that influence the longevity of dental implants include the patient's oral hygiene practices, overall health, and lifestyle habits like smoking. Regular dental visits for cleanings and check-ups are also critical in ensuring the implant remains healthy and free of complications. Additionally, the quality of the implant materials and the expertise of the dental professional performing the procedure can significantly impact the durability of the implants.
