Founder · Global Aesthetic Director

Established Colombia, 2019

A Global Smile Design Vision, Delivered by a U.S.-Licensed Dental Team

Founded by Dr. Mario Montoya, whose career spans more than 26 years in cosmetic dentistry, Smiles by Mario Montoya began in Colombia in 2019 with a design philosophy that earned international recognition — known to many as “The Billion Dollar Smile.” Today, that vision continues at the flagship Atlanta location in Sandy Springs, refined into a health-first approach centered on ultra-natural aesthetics, facial harmony, and long-term oral health, where every patient experience is guided by careful planning and refined results.

At our Atlanta location, clinical dental care is performed by U.S.-licensed dentists. Dr. Mario Montoya serves as the global brand and aesthetic founder, while our local clinical team provides evaluation, treatment planning, and care in Georgia. This structure allows patients to experience the recognizable Smiles by Mario Montoya philosophy with the clinical oversight and standards of a local U.S.-licensed dental team.

From smile design and porcelain veneers to full-mouth rehabilitation and dental implants, our approach begins with understanding your goals, your oral health, and the details that make your smile naturally yours.

What we do

Signature Cosmetic and Restorative Services

Our homepage focus is centered on high-value cosmetic and restorative care, supported by digital planning and an in-house laboratory workflow. Each treatment is personalized around your facial features, oral health, bite, and long-term goals.

Ultra Natural Smile Design

Our signature Ultra Natural Smile Design approach is built around balance, proportion, and authenticity. Rather than creating a smile that looks overdone, we focus on enhancing your natural features while respecting your facial harmony, bite, and oral health.

Porcelain Veneers

Porcelain veneers can improve the shape, color, symmetry, and overall appearance of your smile. Veneer treatment is planned with a health-first mindset for a refined result that still feels natural to who you are.

Full-Mouth Rehabilitation

Designed for patients with worn teeth, missing teeth, failing prior dental work, or bite concerns. These cases are carefully planned to improve appearance, comfort, stability, and function across the full smile.

In-House Digital Dental Laboratoryee

A fully integrated in-house lab with CAD/CAM milling, 3D printing, ceramic furnace, and sinter furnace capabilities — coordinating digital workflows closely within the same clinical environment.

What we do

Signature Cosmetic and Restorative Services

Every plan starts with your face, your bite and the result you want to see. From there we choose only the treatments that earn a place in it, and our in-house lab carries the design all the way to the final ceramics.

I had an excellent experience at Smiles by Mario Montoya in Atlanta. I previously had my Opulent Smile done at Mario's office in Cali, Colombia, and I was impressed that the Atlanta office provided the same high level of professionalism and care. The team was welcoming, all my questions were answered, and I felt comfortable throughout my visit. The office was clean and organized, and the staff delivered outstanding customer service. I am very happy with my smile and highly recommend Smile By Mario to anyone seeking quality dental care and beautiful results.

I had an absolutely beautiful experience at the Dr. Montoya Atlanta location. From the moment I walked in, Tasha at the front desk made me feel so welcomed with her warm energy, genuine kindness, and outstanding hospitality. She truly set the tone for such a comforting and positive visit. Leo, the dentist, provided exceptional care and was incredibly thorough throughout the entire appointment. He took the time to explain everything in detail, made sure I was comfortable, and showed genuine concern for my dental health and overall experience. His professionalism, patience, and informative approach made me feel completely at ease and confident in the care I was receiving. The doctor assistants Tomei, Leo, Natalia, and Nika all provided exceptional service throughout my appointment. Overall, the experience was excellent, in-depth, and truly exceeded my expectations. I highly recommend the Dr. Montoya Atlanta location to anyone looking for compassionate, knowledgeable, and high-quality dental care.

If you're searching for your next dental home—look no further than the Atlanta, Georgia - U.S.A - Location - Smiles By Mario Montoya! From the moment you walk in, you're welcomed with so warmly by Tasha and Daniella, who instantly make you feel like part of the family! Let me rave for a moment about Dr. Villalobos—hands down, the BEST dentist I’ve ever had work on me. She is incredibly knowledgeable, gentle, and explains everything clearly, making you feel completely at ease. Her skill and professionalism are unmatched, and I’ve never felt so confident in a dentist's care. Nika was so nurturing during my cleaning, walking me through everything and ensuring I was informed and comfortable the entire time. Alma and Katherine were super sweet and made taking x-rays and settling into the chair (with a warm blanket, no less!) a breeze. They truly care about your comfort. After my visit, Soraya helped break down the next steps in my dental journey and walked me through financing options, which was a huge relief. It’s rare to find an office that not only provides top-notch care but also works with you to make it affordable. And let’s talk about the office itself- Opulent!!!!!—it's located in a gorgeous, luxurious, and spacious building that makes you feel like you’ve walked into a high-end spa rather than a dental office. I’ve never been this excited to visit the dentist before—but the Atlanta team - Smiles By Mario Montoya has truly become my dental family and home. Do yourself a favor and go see them today. You won’t regret it!!!!!!!
