Aesthetic Dentistry Georgetown

Since Dr. Mandy opened the practice in 2005, Aesthetic Dentistry has been dedicated to a relationship-centered approach to the finest care available. This means that while it is always the patient’s option, we must be aware of the most advanced care dentistry offers, and ensure that you have the opportunity to select the treatment that matches your dental goals and situation. Your experience will be grounded in a ‘Whole Health’ approach, ensuring your awareness of your dental health as well as its impact on the rest of your body and quality of life. Dr. Mayo, one of the founders of Mayo Clinics, stated that “a person with a healthy mouth lives an average of 10 years longer” and that is even more true today!

Many people don’t have great dental health or love their smile. At Aesthetic Dentistry of Georgetown, we create beautiful healthy smiles and give you options to keep your teeth for life.
