Teeth whitening gel is use on in-office treatments as well as for DIY regimens. Most of these gels will effectively show positive results over the period of two weeks. Majority of these gels are compose of either hydrogen peroxide or carbamide peroxide as it active teeth whitener.
Carbamide peroxide is good for DIY tooth whitening regimen. The standard concentration of carbamide peroxide that suits for all kinds of teeth is 16%. This strength level will do no harm to sensitive teeth. For those who had never tried using any tooth whitening gel before you are suggested to use those products that have 10% of strength to avoid your teeth from getting shock on the whitening agent.
Hydrogen peroxide is a stronger substance and can be found on most in-office teeth bleaching gels. It has 3 times more power than hydrogen peroxide and is not recommended to use on DIY regimen unless you have dentist prescription. A 16% strength of carbamide peroxide is only 5.3 solution of hydrogen peroxide.
Another ingredient on good tooth whitening gels is fluoride. Fluoride can counter-act the harsh power of peroxide. Those products that have fluoride suits best for those who have sensitive teeth.
There are some bleaching gels that contains potassium nitrate. This also acts like fluoride on the tooth. This substance is approved by the FDA and is said to be a good protector of the tooth’s enamel against the harsh power of peroxide. This substance is not just found on teeth whitening gel but also on tooth bleaching toothpastes.
