Meet Dr. Marina Ambridge

Welcome to my dental practice, where we provide a unique and proactive approach to dental and overall health. As a highly trained dentist, I have dedicated several years to additional post-graduate training, enabling me to identify risks and causes of dental and medical issues such as teeth cracks, cavities, bleeding gums, TMJ, heart issues, Alzheimer’s, diabetes, and more. Through advanced techniques like saliva DNA testing, occlusion (bite) analysis, and others, I can help minimize the chance of dental and medical issues arising in the future. With specialized training in complex full mouth rehabilitation, including cosmetic, orthodontic, and implant dentistry, I have honed my skills at prestigious institutions such as The Kois Center, Progressive Orthodontics, and Ti-Max Implant Institute. Additionally, I share my knowledge by teaching a specialized course to fellow dentists, focusing on leveraging orthodontics to enhance the predictability and minimize invasiveness of their cosmetic dental procedures for their patients.

As a Fellow of the Academy of General Dentistry and a lecturer at the American Academy of Cosmetic Dentistry, I am among the top 7% of general dentists in the USA who have achieved the esteemed Fellowship degree. Additionally, I received an award for the highest academic achievement in all four years of dental school from the University of Toronto, highlighting my dedication to ongoing education.

To stay at the forefront of dental advancements, I devote over 250 hours each year to continuing education, surpassing the 30 hours required from regular dentists to maintain their license. Recognized as one of the Top 40 Under 40 dentists in the USA and a three-time recipient of America’s Best Dentist award, I am committed to delivering exceptional care. Our dental practice employs a unique blend of orthodontic and cosmetic dentistry to ensure ideal outcomes for cosmetic cases. Leveraging my experience in the fashion industry and the use of dental fillers and Botox, I bring a distinct perspective to facial esthetics. I have also been featured in major media outlets, including NBC radio, Dr. Howard Farran’s Dentistry Uncensored podcast, and AGD Impact magazine.

Our primary objective is to provide you with a beautiful smile and healthy teeth using cutting-edge dental technology and techniques. We utilize advanced tools such as Intraoral 3D Scanner, Panoramic, Cephalometric, and CBCT 3D x-ray, as well as 3D printers, Ministar advanced medical plastic molding machines, and powerful analytical software. These enable us to create a 3D digital model of your teeth for better diagnosis and 3D printing of most dental devices within our practice.

We understand the importance of pain and anxiety management during dental procedures. That’s why we offer a comfortable environment with massage dental chairs, noise-canceling headphones, and Netflix to help you relax. Our SmartGate dental injection aid eliminates discomfort during anesthetic injections. We also provide various levels of anesthesia at our office, including “Laughing Gas” to reduce dental anxiety, oral conscious sedation for a relaxed experience during the procedure, and deep IV sedation with the assistance of an anesthesiologist for full general anesthesia. Rest assured that all levels of sedation and anesthesia are safe and monitored by professionals.

By choosing our practice, you embark on a journey towards a healthier, more beautiful smile. Contact us today to experience the exceptional care and expertise that sets us apart.
