Dr. Guy M. Lewis – Board-Certified Cosmetic Dentist

Meet Dr. Guy M. Lewis

For our Houston, TX, board-certified Cosmetic Dentist, Dr. Guy M. Lewis, dentistry is a passion and represents a lifelong commitment to his patients. Dr. Lewis loves seeing his patients’ lives changed by restoring beauty, confidence, and health. As the only Founding and Accredited Member of the American Academy of Cosmetic Dentistry (AACD) in Houston, Dr. Lewis is recognized throughout the world by peers and patients alike as a pioneer in cosmetic dentistry.

He also serves as an Adjunct Professor of Dentistry at Baylor College of Dentistry and is a Featured Speaker at annual AACD and industry conventions.

There are many dentists that claim to perform cosmetic dentistry, but there are very few like Dr. Lewis who have devoted their careers to the art and science of cosmetic dentistry. Experience, dedication, and skill all matter, but it also takes a true artist to create a smile that complements a person’s facial features and personality. As the Official Cosmetic Dentist for the Houston Rockets, Astros, Dynamo and Aeros, Dr. Lewis has transformed the smiles of many well-known figures and athletes, including USA Olympic champions and pageant contestants for Miss Texas, Miss Teen Texas and Miss Hawaiian Tropic. Having implemented a patient-first philosophy for 30 years, Dr. Lewis is an award-winning dentist who creates awe-inspiring smiles with his own brand of No-Prep G. Lewis veneers, porcelain crowns, dental implants, smile makeovers, and much more.

Skills & Specialties

Dr. Lewis has been interested in the field of dentistry since childhood, when he was inspired by his aunt who worked at a dental office. He saw how much quality dental care improved people’s lives and knew he wanted to become a dentist and open his own practice one day. Today, he leads a dental practice in The Woodlands, TX, and 2 in Houston, TX, where he offers his patients cosmetic dentistry (porcelain veneers, teeth whitening, tooth-colored fillings, smile makeovers), general and family dentistry (preventative care), and restorative dentistry (crowns, implants).

Dr. Lewis has surrounded himself with a talented team of trained dental professionals who share a common goal that has earned TCCD a reputation as one of the leading cosmetic dentistry practices in the nation. He wants to make every dental visit as enjoyable and efficient as possible for patients who visit from Houston, TX, across the nation, and around the globe.

Education & Training

In 1984, he earned a Doctor of Dentistry from Baylor College of Dentistry in Dallas, TX, the same year he Co-Founded the American Academy of Cosmetic Dentistry with other internationally renowned dentists. At the time, cosmetics was just becoming a specialized area of dentistry as it began to grow from the use of orthodontic appliances to improve the appearance of smiles into the use of porcelain restorations and other new advancements for enhancements. In 1989, Dr. Lewis became accredited by the AACD, the youngest cosmetic dentist to ever do so.
