Benjamin J. Martin, DMD, MS, graduated in 2011 from the University of Pennsylvania School of Dental Medicine and then in 2014 pursued his Certificate for Oral Biology and Specialty in Orthodontics from the Texas A&M Baylor College of Dentistry.

“A straight, beautiful smile is universally sought after. While it is an aesthetically pleasing feature, it enhances a person’s overall health in many ways. When a person’s teeth are not in alignment, the function of the teeth and jaw are not optimal; therefore, food may not be digested properly, excellent oral hygiene is difficult, wear and tear on the teeth is advanced, and the pressure from the misalignment may cause headaches and facial pain.

Seeing these transformations in my patients, along with a renewed self-esteem and a new desire to smile, is by far the greatest reward of my profession as an orthodontist.

As a young grade school student, I always knew that I wanted to pursue a career in healthcare. It wasn’t until I attended a dental mission trip to Honduras that I knew that I wanted to be a dentist. While in dental school, my passion and interest in orthodontics grew. I learned and was inspired by some of the best orthodontists at Baylor. I feel very blessed to be able to use my skills, education, and the latest orthodontic advancements to perfect smiles.”
