Tooth reshaping or dental contouring, is a conservative and inexpensive option to help improve the appearance of your smile. Dental X-rays may be taken before the reshaping and contouring begin to ensure that your teeth are healthy. Your dentist will then mark your teeth with a pen to highlight areas that need sculpting. A sanding instrument is used to artfully Eliminate or minimize imperfections on the Surface of the Teeth, and Sandpaper-like Strips may be used to contour the Sides of the Teeth.
