Nitrous Oxide (laughing gas) can help put you at ease. We offer wireless headphones for listening to your choice of music during your procedure. Sit back and relax while watching TV shows of your choice. We have tvs in each of our treatment rooms. Our office is easily handicap accessible with ramps in both the front and rear entrances.


Digital X-Rays X-rays are a focused beam of x-ray particles passed through bone and teeth which produce an image on special film showing the structure through which it passed. This provides the familiar black and white images doctors and dentists use to diagnose problems and disease. Without an x-ray of the whole tooth and supporting bone and gum tissues, there would be little way to detect infection or pathology that requires attention. In our office, we use digital radiography which allows us to take x-rays using up to 90% less radiation than conventional film x-rays.  The result is a highly detailed image of your mouth that can easily be enhanced to better diagnose dental concerns and determine the very best treatment for each case.

Paperless Charting Our office is a completely digital (paperless) dental office. This means all x-rays and charting are made and recorded with the aid of the computer. This technology allows us to maintain your dental records electronically.  The computer makes charting accurate and precise, thus making it easy to read and see up-to-date information. Digital charting standardizes the charting process so it is clear, accurate and precise. This method also allows us to quickly and securely share information with your other health care providers.

Electronic Scaling Dental hygienists traditionally perform scaling by hand. However, new and advanced technology has led to more modern methods such as electronic scalers. This sophisticated tool allows dental cleanings to be performed more efficiently and in less time. To achieve best results, both electronic and manual scaling methods are combined for dental cleanings.

Prophy Jet We offer Prophy Jet, which is air polishing for stain removal.

Air Abrasion Allows us to provide drill-less procedures to our patients. Many times small restorations can be prepared using air abrasion without the need to numb the patient.

Intraoral Cameras We use small cameras about the size of a pen, called intraoral cameras, to help clearly see the condition of your teeth and gums. With this advanced technology we can zoom in on small diseased areas, cracks, chips and worn metal fillings with extreme precision. The full-color images taken with the intraoral camera are sent to a computer screen so we can clearly see and diagnose dental problems much earlier than with traditional dental technology. Because images are displayed on our screens, patients will also be able to see areas being worked on and are able to gain a better understanding of dental procedures being performed.

Telescopic Loupes We use loupes to provide us with a magnified field of view.

Electronic Claims Because we submit electronically to the insurance companies we are able to process your claims fast and easily.
