Thin plastic whitening trays are made from models of your teeth. They are designed to hold a whitening gel flush against your teeth. You place a professional-strength gel in each tray and wear the trays in your mouth from 30 minutes to several hours every day, depending upon the strength of bleaching solution you choose. The bleaching gel penetrates the tooth enamel and gently removes stains caused by foods, beverages, tobacco, and aging, without harming the enamel.
With take-home teeth whitening, you can control the degree of whitening you desire and reuse the trays in the future to touch up your smile. A significant change in tooth color is usually seen in two to six weeks.
Accelerated whitening is another option for teeth whitening which yields even whiter and brighter teeth in just one office visit. The advantages of this in-office procedure are that the bleaching solution is applied by Dr. Best and is chemically activated. It strengthens tooth enamel, and reduces tooth sensitivity because it contains potassium nitrate and fluoride.
For a dazzling white smile, we highly recommend following up with a take-home whitening kit. The results are dramatic and long lasting.
Some Stains may Persist
Regardless of which tooth whitening method you choose, teeth with dark gray stains caused by tetracycline or fluorosis are resistant to teeth whitening. Results may be less noticeable. However, if you commit to whitening your teeth daily for up to 3 months, you are likely to achieve a positive result that you will be happy with.
Please note that dental restorations such as crowns and fillings will not lighten. On occasion, teeth may be stained in a way that limits the effectiveness of tooth whitening. In those instances, porcelain veneers or crowns are an excellent alternative.
