Cosmetic Dentistry and Tooth Whitening

Whether it is as simple as zero sensitivity bleaching (tooth whitening) to porcelain veneers or to extreme smile makeovers, the Colchester Dental Group is world-famous for their accomplishments in cosmetic dentistry. Both of our dentists are members of the American Academy of Cosmetic Dentistry. Dr. Marty Zase is the only dentist in eastern Connecticut Accredited in cosmetics by the AACD.

Cosmetic dentistry offers many options for people who are not completely satisfied with their own smile.

According to the National Beall Study, cosmetic dentistry can change lives, one smile at a time, by increasing your self-confidence and making you look happier, more attractive, more successful, and better educated. Click here to view the results.
