With proper care, dental implants can remain healthy and functional for 20–30 years or even a lifetime. This longevity hinges on consistent oral hygiene—brushing twice daily, flossing carefully around the implant site, and attending regular check-ups. Avoiding tobacco and maintaining a balanced diet further boosts implant success. Given their durability, implants are often considered one of the most cost-effective solutions for tooth replacement over the long term.
