The Science behind our Gel
Using the newest and finest ingredients in Hydrogen peroxide gel technology Million Dollar Smile's Smiley White whitening pen whitens teeth without the high-intensity lights used in expensive in-office procedures. It’s added potassium nitrate substance works as a front line sensitivity blocker, working best on the weakest enamel and most sensitive teeth.
Carbamide Peroxide vs. Hydrogen Peroxide
Carbamide Peroxide whitening gels take on average 4 times longer to completely activate as does pure hydrogen peroxide gel does. Carbamide peroxide reaction chemically takes about one full hour. Carbamide gels must also convert to hydrogen peroxide in order to whiten. Its equivalent strength in hydrogen peroxide form is only about 1/3.
Many take-home kits and systems still use Carbamide peroxide as the main whitening agent yielding less results than that of fast activating Hydrogren Peroxide.
Smiley White Night-Time Whitening®
It has been clinically proven that whitening at night can significantly increase whitening results. Whitening at night, just before bedtime, is best to do because of less salvia flow while sleeping. This allows the hydrogen peroxide gel formula to work at its full potential bubbling and removing stains away much faster. Rinsing is not necessary but if you feel you must, wait 15 minutes and then rinse before bedtime. The process works best when left on overnight to promote Night-Time Whitening®. Use daily for up to 10 days. Whitening results will vary, as some see immediate results after just a 15-minute application and others might see results after 2-3 applications.
