Enamel shaping involves removing a slight amount of enamel to improve the appearance and at times the function of teeth. This is often used to correct uneven edges of the front teeth, smooth teeth with minor chipping, or round off sharp pointed tips of the teeth making the smile more proportioned and even. In some situations enamel shaping is used to correct a person’s bite.
