Dental implants are designed to be a long-term solution for missing teeth, with the implant itself potentially lasting a lifetime if properly cared for. However, the crown—the visible part that resembles a natural tooth—may need to be replaced after 10 to 15 years due to normal wear and tear. The lifespan of a dental implant can vary based on factors like oral hygiene, lifestyle habits, underlying medical conditions, and regular dental visits. For best results, it's important to maintain good oral care and consult with a dental implant specialist for personalized guidance.
