At your initial examination we take a comprehensive medical and dental history, conduct an evaluation of the mouth tissues and how your teeth function together, take necessary x-rays and appropriate digital photos, and discuss any cosmetic concerns. We then create a treatment plan through thoughtful analysis and collaboration.
