No-Pressure Consultations

During our “Save Your Tooth” consultations, you will be given one-on-one time with your doctor. They will get to know you and take a close look at your tooth or teeth as part of your introductory examination. We will also answer any questions you may have and go over a custom treatment plan to get you out of pain or discomfort.

Great guys and very professional, beautiful office. I actually referred my aunt to them and she couldn’t be happier with the work they did on such short notice! Hope I don’t need a root canal, but if I do, I know where I’m going!
