People love a bright white smile, and there are a variety of products and procedures available to help you improve the look of yours. Many people are satisfied with the lightness they get from daily oral hygiene and regular cleanings at your dentist’s office, but if you decide you would like to go beyond this to make your smile look brighter, you should investigate all of your whitening options. Professional bleaching uses different forms of peroxide to lighten teeth at both the external layer – enamel – and internal layer – dentin. In office bleaching provides the fastest, most dramatic color change. Custom made bleaching trays and higher concentration bleach provided by a dental office also lead to excellent results, typically in 1-2 weeks.
