Here at Yamashiro Orthodontics, we do our best to offer state of the art treatments in a warm comforting environment. We have digital x-rays that significantly reduce the amount of radiation one is exposed to during imaging, and are much more comfortable than the ones that normally go inside your mouth.

The Yamashiro Orthodontics office is about 80% digital which is friendly to the environment and improves the continuity of care and communication between us and your different medical and dental providers. We have free Wi-Fi for your use in our lobby/waiting room as well as power strips for charged your devices as needed.  There are also refreshments, as well as a nice tooth brushing area for you to use once you are done with your afternoon snacks.
