Dental implants are designed to be a long-term, permanent solution. The titanium post, once integrated with the bone, can last a lifetime with proper oral hygiene and regular dental check-ups. The crown may require replacement after 10-15 years due to normal wear, but the underlying implant remains durable. If you break your implant, abutment (chimney), screws, you may require replacement but with great care and avoiding certain high stress foods like gum chewing, your implants can be a great solution.
