In addition to bleaching solution, whitening strips are increasingly being used as a preferred tooth whitening product. For instance, you are now able to get your hands on a set of Crest Whitestrips Supreme from any convenience store. The flexible, invisible strips are coated with an enamel-safe tooth bleaching gel. To whiten your teeth, you simply place the strips on your teeth and wear them for about 15 to 30 minutes each day. After a period of about 21 days, you should be able to see a significant difference on the brightness of your teeth.
