Twenty First Century Dentistry

In the old days, when the only restorative materials were amalgam or gold, and the only esthetic material was denture teeth, our profession had a hard time. Today, we can do better dentistry, in a less toxic, more individualized, more environmentally friendly way than ever. We have as many choices of attitude before us as we do techniques and materials so we can provide a friendly, gentle, comfortable and efficient high-tech Dentistry. We favor preventive healthcare and screenings to detect tooth decay and other issues in the early stages, when they are easier to treat, cheaper and less painful. When you choose a Biological Dentist you know you are getting the safest experience for your overall health!
We use minimally invasive, tooth preserving, known as Biomimetic dentistry.
Dr Preda is also a proud member of the Holistic Dental Asociation! She belives in improving your overall health through Dentistry!
