Smile Advanced Dental Care





Prospero Matos, DDS
General Dentist, Owner

Dr. Prospero Matos was born in New York before relocating to the Dominican Republic at an early age. There he received his Bachelor’s in Dental Sciences from the Universidad Iberoamericana (UNIBE) in 1998. He was later accepted into the New York University College of Dentistry (NYUCD) advanced placement program for foreign-trained dentists and graduated with his DDS in 2011. Dr. Matos practiced dentistry in New Jersey from 2011-2014, then relocated to Texas with his wife Lela.

Dr. Matos decided from a young age that he wanted to become a dentist due to his experiences with his own caring and patient dentist. He says, “As a child, I remember thinking that the sight of my panoramic radiograph on the old view box with all of the crazy jumbled up teeth was the coolest thing ever.”

As a practitioner, Dr. Matos most enjoys seeing a patient regain self-confidence by being able to smile fully. He combines the latest state-of-the-art technology to provide patients with a thorough and caring examination to meet each patient’s needs and wants.

Dr. Matos is a recipient of the Dr. Bernard E. Rudner Memorial Award for clinical excellence from NYUCD. He maintains memberships in the American Dental Association, Academy of General Dentistry, Texas Dental Association, and Hispanic Dental Association. In addition, Dr. Matos has participated in dental outreach programs, serving people in need in the Dominican Republic, Honduras, and Mexico.

Dr. Matos has children Diego and Isabel and welcomed Amelia Kate in 2018. In addition, he and his wife Lela have an English Setter fur baby named Potter.

Dental Family

Lela Matthes Matos, DDS
Pediatric Dentist

Dr. Lela was born and raised on a farm in Bay City, TX, with her parents and older sister. As a young girl, she spent countless hours in her grandfather’s orthodontic office and knew from a young age that she wanted to follow in his footsteps, practicing in the field of dentistry.

Dr. Lela attended Austin College in Sherman, TX, where she received her Bachelor of Arts Degree with a Major in Biology. She received her degree in dentistry at New York University College of Dentistry. After dental school, she spent two years at Staten Island University Hospital (SIUH) in Staten Island, NY, as a General Practice Resident and served as Chief Resident her second year. She completed her 2-year postgraduate education in Pediatric Dentistry at SIUH under the direction of Dr. Steven Schwartz, a pioneer in the specialty of Pediatric Dentistry. Dr. Lela’s comprehensive training at SIUH makes her well-trained in handling dental needs among patients of a wide range of ages and medical issues.

While at NYU College of Dentistry, she was invited to attend an Outreach Program in the Dominican Republic where she provided much-needed dental care to people that otherwise did not have access. Since finishing her pediatric training, she has been invited back by NYU to serve as faculty on their Outreach Programs to Nicaragua, Mexico, and Nepal. Being able to provide this type of service for those in need is on the top of her list of things that make her happiest.

Dr. Lela met her best friend and husband, 

Dr. Prospero Matos, in dental school. They love spending time together cooking, traveling, and doting on their daughter, Amelia, and furbaby, Potter.
