But providing a comfortable environment for our patients doesn’t mean we have skimped on technology. Not only does high-tech dentistry mean less time in the dental chair for our patients, but it also means treatment is that much more comfortable. We are proud to offer laser dentistry, digital x-rays, intraoral cameras, rotary endodontics, iTero scans, and more.
