How do the at home teeth whitening systems work?



  1. 0 Votes

    There are a variety of teeth whitening systems out in the market, but all of hem contain bleach. The small amounts of peroxide bleach in the whitening gel removes certain surface stains from drinking tea, coffee, and the like. However, studies show that these teeth whitening products are more keen on working for people with yellow undertones in their teeth, not gray undertones. Teeth whitening gels can be used with mouth trays, as teeth strips, sometimes they even come packaged as pens with little brush tips at the end.
