With various oral care teeth whitening kits hitting the market we sometimes have a hard time deciding how to buy teeth whitening kits. All the teeth whitening kits work on the same formula. Most of the popular brands of teeth whitening kits come with a set of mouth trays and a whitening gel.
Purchasing Teeth Whitening Kits
While purchasing it we should keep in mind all the whitening gels contain either carbamide peroxide or hydrogen peroxide but its concentration is what matters to us. The whitening gel usually contains up to 30% of carbamide peroxide, though the recommended quantity is 15%. This carbamide peroxide breaks down to 3-10% of hydrogen peroxide. This is the recommended quantity of teeth whitening gels. If you find the concentration of peroxide higher than 30% you should look for other brand as its side effects might be severe.
Just go through the label on teeth whitening kits see how long you need to let the peroxide be in contact with the teeth. The longer the duration, the more will be the inconvenience. After all who wants to remain in that awkward position for long ?Moreover the whitening gel is bound to touch your gums and it may cause irritation , therefore go for brands which do not require you wear the mouth tray for more than 20-30 minutes.
It is always good to get medical advice before purchasing any teeth whitening kits. In some rare cases tetracycline staining may not be whitened with these bleaching kits. If the severity of your stains is such that only laser technique will be effective for you, there is no point going for these teeth whitening kits.
Finally checking online offers are always full of surprises and freebies. Why not order it online and avail of some of the freebies like free tooth care DVD and eBooks. Moreover, there is no risk involved, you can simply pay for shipping and handling and try the product.
