Dental implants are replacement tooth roots, which provide a strong foundation for fixed (permanent) or removable replacement teeth. Dental implants can improve your appearance because they look and feel like natural teeth. They can also improve your speech. With poor-fitting dentures, the teeth can slip within the mouth causing you to mumble or slur your words. Dental implants allow you to speak without the worry that teeth might slip and thereby can restore lost confidence. They also increase your comfort and chewing efficiency because they become part of you, eliminating the discomfort of removable dentures.
