Dental Implants in Novato

Dental implants are designed to provide a foundation for replacement teeth that look, feel, and function like natural teeth. The person who has lost teeth regains the ability to eat virtually anything and can smile with confidence, knowing that teeth appear natural and that facial contours will be preserved.

Dental implants are changing the way people live. With them, people are rediscovering the comfort and confidence to eat, speak, laugh and enjoy life. For more information about dental implants or to schedule a consultation appointment, call our office in Novato, CA at 415-209-6060.
