A beautiful smile showing clean, white teeth gives a tremendous boost to your confidence. Most people experience some discoloration of teeth over the years, either from surface or extrinsic stains or internal ones. Treat stains caused by coffee, wine, tobacco and pigmented foods with at-home whitening or have a professional, in-office whitening done regularly. For intrinsic discoloration, consider composite bonding or the application of veneers to the affected teeth, which provides a more permanent solution.
