Welcome to Our Practice

Welcome! Since 1963, Southborough Dental Associates has been providing the best dental care for patients in Southborough and its surrounding communities. Dr. Egan, Dr. Zaterka, and Dr. Madruga have 55 years of combined experience in dentistry . Although our cosmetic techniques and technologies have certainly changed over the years, our main philosophy has not. That philosophy is very simple - Take care of the patient. We integrate beautiful cosmetic dentistry with a focus on oral health and a natural looking, long lasting result.
