our mission

Your teeth are more precious than gems, and should be treated as such! At Sapphire Smiles, our mission is simple: to provide excellent, accessible dental care for lifelong oral and overall wellness. We do everything possible to ensure you stay comfortable, confident, and informed about your dental health, whether it’s walking you through a treatment plan, going over your financing options, or answering any questions you may have. Dr. Antoun is proud to offer modern dentistry using state-of-the-art equipment for efficiency and accuracy. You’ll feel right at home in our hospitable, welcoming office. When you come to Sapphire Smiles, we’ll help you create a dazzling smile that will last a lifetime.

Meet Dr. Antoun

Born and raised in Cairo, Egypt, Dr. Antoun has always been fascinated with art and science. Dentistry provided the perfect career that would allow him to combine both of these interests. Dr. Antoun studied dentistry in Cairo and practiced in the field for three years before moving to America with his wife, Mary. 

While living in New York, Dr. Antoun received his second dental degree from New York University where he also gained valuable experience by serving as a teaching assistant. He graduated at the top of his class academically and clinically and became a member of the Omicron Kappa Upsilon Honor Dental Society. He was also enrolled in an Honors Clinical Concentration Program in Aesthetic Dentistry, and received the Arthur Charles Hull and Samuel & Hannah Holzman Award for demonstrating the greatest proficiency in endodontics in his class. Dr Antoun is a member of the American Dental Association (ADA), Texas Dental Association (TDA), and Greater Houston Dental Society (GHDS).

After graduating from NYU, Dr. Antoun and his wife moved to Texas where they quickly established roots and became involved in their community. Dr. Antoun was promoted from an associate dentist to a lead dental director, with the responsibility of overseeing three other offices. In his spare time, he enjoys playing soccer and spending quality time with Mary and their two small children. Dr. Antoun is proud to offer superior, individualized dental care in Houston Heights.

Giving Back to Houston Heights

Like excellent dental care, a quality education can change lives for the better. Dr. Antoun knows from firsthand experience what it is like to struggle to have access to higher education. That is why we are proud to partner with EMERGE, a local non-profit that supports ambitious, underserved students to help them attend and graduate from universities across the nation. For every new patient that walks through our doors, we will donate $10 to support EMERGE’s mission. At Sapphire Smiles, we strive to make our community healthier and happier.
