Dr. David T. Constant was raised in Cupertino and is a local graduate of Monta Vista High School. He received his Bachelors in Biochemistry from the University of California at Davis and his Dental Degree and Orthodontic Certification from the University of California at San Francisco. He received a number of awards throughout dental school including the U.C.S.F. School of Dentistry's Professionalism Award and Student Research Award. He graduated with highest honors from U.C. Davis and was elected to the O.K.U. National Honorary Dental Society at U.C.S.F.

Dr. Constant returned to Cupertino with his family and maintains a practice limited exclusively to Orthodontics for children and adults. He is currently a member of the American Association of Orthodontics, American Dental Association, California Dental Association, Santa Clara Dental Society, and Mid Peninsula Dental Society.

Dr. Constant continually strives for excellence in the practice of Orthodontics by keeping up with the latest developments and techniques by frequently attending continuing education courses and local study groups. His practice has been geared towards the treatment of young children with emphasis on early treatment to intercept bite problems. Early treatment can in many cases prevent the development of more severe bite problems and reduce the need for excessive treatment in the future. The practice also maintains a large percentage of adult patients engaging in the most current adult treatment modalities including the more recent advancement, the Invisalign system. These 'invisible' braces are ideal for the busy professional.
