We are among the few practices that have Cone beam radiography where we can take 3-D images, CBCT. This is essential for our patients who are interested in Implants and wisdom teeth extractions. We also use 3-D radiography in Root Canal Therapy to view and detect infection and canals. Overall, we have state of the art technology, but at the end of the day, it is our one on one relationship that matters the most. It is the relationship between our staff and our patients that sets us apart. We are also fully digital where we use Digital radiography, digital records and digital imaging. We also provide Electronic Anesthesia that is a rarity in dental offices.
