Most of us have at least a few teeth that are worn down, rotated, or slightly crowded. The dentist can simply take a polishing disk and, in a few short minutes, gently re-contour teeth to match in length, shape and form. This will round off sharp edges which are prone to chipping. It will trick the eye and make teeth appear straight. It can take attention away from minor flaws and mute imperfections. This is a very conservative treatment that requires no anesthetic and only takes a few minutes.
