Our Technology

Digital X-Rays X-rays are a focused beam of x-ray particles passed through bone 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. Using this technology, we are able to take an x-ray of your mouth by using a small sensor which records the image of your teeth and sends it to a computer. 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, and cuts down the unnecessary paperwork used with traditional paper charting. Traditional paper charting is difficult to keep standardized from doctor to hygienist to assistant. Even handwriting differences and coding make the charts look different. The computer eliminates this problem by using consistent charting methods that are accurate and precise, making it easy to read your dental chart and see up-to-date information. Digital charting standardizes the charting process so it is clear, easy to understand, and enables us to provide the most accurate and precise care to our patients. When needed, this method also allows us to quickly and securely share information with your other health care providers. DIAGNOdent Providing the absolute best service to our patients is of the highest importance to our office. To aid in achieving this goal, we use a new high-tech device called the DIAGNOdent. This small tool is a portable laser that allows us to detect cavities on the chewing surface of the back teeth that would have otherwise gone undetected by previous methods. Diagnosing cavities in the back of the mouth using traditional methods is difficult; studies even show that 50% of cavities are left undetected in these areas. However, the new DIAGNOdent enables us to locate and treat these cavities, putting a stop to further decay. The laser is easy to use, harmless, and will alert us with an audible signal if it detects a cavity. It will even calculate the approximate size of the cavity so we can better plan treatment. By using this device, you can rest assured that cavities will be accurately detected and treated in their infancy. Electronic Scaling Dental hygienists traditionally perform scaling by hand. However, new and advanced technology has led to more modern methods such as electric scalers. This sophisticated tool allows dental cleanings to be performed more efficiently and in less time. To achieve best results, both electric and manual scaling methods are combined for dental cleanings. ProphyJet We offer prophyjet, 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. Oraverse anti numbing OraVerse (phentolamine mesylate) is an injection that reverses the effects of local anesthetic with a vasoconstrictor (numbness after a dental procedure) and accelerates the return of normal sensation and function. It helps you reduce the unwanted and unnecessary lingering numbness in the lips and tongue after routine dental procedures. Electronic Claims Because we submit electronically to the insurance companies we are able to process your claims fast and easily.

We have tvs in each of our opertatory rooms. Warm Blankets and Towels We offer warm blankets and towels to help you feel comfortable during your visit.
