Dental Excellence


COVID-19 – Updated 5/3/20

Infection control has always been a top priority for our practice and our office follows infection control recommendations made by the American Dental Association (ADA), the U.S. Centers for Disease Control and Prevention (CDC) and the Occupational Safety and Health Administration (OSHA). We follow the activities of these agencies so that we are up-to-date on any new rulings or guidance that may be issued. We do this to make sure that our infection control procedures are current and adhere to each agencies’ recommendations. We made some changes to help protect our patients and staff. Our office will communicate with you beforehand to ask some screening questions. You’ll be asked those same questions again when you are in the office. Appointments will be managed to allow for social distancing between patients.

We will do our best to allow greater time between patients to reduce waiting times for you, as well as to reduce the number of patients in the reception area at any one time. We look forward to seeing you again and are happy to answer any questions you may have about the steps we take to keep you, and every patient, safe in our practice.

Have beautiful teeth with our quality dental services.
