Cosmetic dentistry is now a large part of the dental practice, but Dr. Henry is still the family dentist for many people in Seguin.

With growth came the need for more space and new technology, so a spacious new office equipped with state-of-the-art equipment was built and operates as Tier One Dental in June of 2009. Now a full range of cosmetic dentistry is available, along with the traditional services of a family dentist in Seguin.

In 2011, Sam had the honor of being one of twenty one dentists in the state of Texas, to be nominated for the Texas Academy of General Dentistry “Dentist of the Year Award”. This award is considered the most prestigious honor a Texas dentist can earn.

Dr. Henry is very interested in new technologies such as digital photography, digital radiography, and computer technology. He especially enjoys cosmetic and restorative dentistry such as ceramic crowns, veneers, bleaching, bridges, composite bonding, and implant restorations.
