At York Hill Endodontics, we use the latest and most sophisticated dental technology.
Amongst the latest is the operating microscope, which allows us to magnify the field of vision by upwards of 20X. Also, we use dental radiography, which replaces the old way of taking xrays and allow us to process the xray much quicker and also to view the image instantly on the computer. As an added benefit, much less radiation is required than before. Lastly, our dental software allow us to transmit your reports electronically to your general dentist as well as allowing you to register or update your information online at your convenience.
