Dental implants are replacement for tooth roots. Implants provide a strong foundation for fixed (permanent) or removable replacement teeth that are made to match your natural teeth. Some advantages of dental implants include improved appearance, speech, comfort, and oral health. Eating will be easier and pain-free. Implants are also very durable. With good care, many implants last a lifetime. Because implants are not removable, there is no need for the messy adhesives to keep your dentures in place.
