Crest Whitestrips Supreme offers the strongest whitening capabilities of any Crest Whitestrips available. They whiten teeth 43% better than Professional Crest Whitestrips and 80% better than Crest Whitestrips. This is because they use 14% hydrogen peroxide gel, with 100mg of gel on each whitening strip. The Professional line uses less than half of the Supreme, which is what makes Crest Whitestrips Supreme one of the best options when it comes to significant whitening. Use the strips for 30 minutes, 1 or 2 times each day until you reach your desired shade results. You will begin to notice a difference in tooth shade within 3 days, but use for 21 days to achieve full results. They may be used as often as needed to maintain tooth coloration. For darker, stained teeth it may be necessary to use 2 boxes before achieving the maximum effects. Each box contains a 3-week supply, with 84 strips total (42 upper and 42 lower). The strips are longer than previous Crest Whitestrips, being 14% longer on the upper and 18% longer on the lower, enough length to cover up to 18 teeth during each treatment. Because these strips are so strong, they may be prone to cause sensitivity in certain individuals. Newer Crest strips adhere better than the older style, which were thin, slimy and slid around on the teeth. Updated strips adhere so well that you can even drink water while wearing them.

If you’re looking for the strongest level of Crest Whitening Strips, then look no further than the Crest Whitestrips Supreme. They’ve already been shown to be more effective than the Professional edition and produce results in just 3 days. These strips are longer, with more concentrated gel to offer optimum whitening on even more teeth, for wider, brighter smiles. The downside to the Crest Whitestrips Supreme is that it may take up to 3 weeks to reach your desired shade. However, once teeth have been whitened they are easier to maintain, so teeth with less staining should have product left over for touch-ups throughout the year as needed. The cost makes these strips a little higher than others in the Whitestrips line, but for 84 strips total included in the kit, the price is competitive.
