Like I said, home whitening kits have become very popular nowadays since almost everyone wants to enhance their appearance by having a pearly white teeth. But to produce good results, whitening kits should be used and applied correctly.
Before, most tooth whitening systems were done in dental clinics and performed by qualified professionals. But nowadays, several teeth whitening products are available to consumers in different applications such as strips, paint-on or tray kits. In Canada, all teeth whitening systems are considered cosmetics, thus Health Canada requires all teeth whitening manufacturers to submit a cosmetic notification with safety and labeling information. The information are reviewed thoroughly by Health Canada to ensure the safety of a cosmetic products. This home whitening kits are also the ones being used by dentists, just that its concentration are lower to those used by professionals. But if you want to have a higher concentration, it must be done by a professional to ensure that the process is correct. They can also give instructions on how to use the take-home whitening products.
How tooth whiteners work?
Peroxide or peroxide generating compounds are the main ingredients in teeth whitening system. Some includes hydrogen peroxide, carbomide peroxide or urea peroxide. The latter two are the most common ingredient and are thrice less potent than hydrogen peroxide. Peroxide acts on the surface of the tooth as well as the next layer below the dentin. If you want to have the best results, choose a whitener that has more peroxide. But take note that teeth whiteners will only be effective on natural teeth and not on caps, crowns, veneer, fillings or dentures. It will last for about six months and should not be used often, twice a year is recommendable.
Studies show that home teeth whitening kits are not harmful when applied correctly and as directed. There are also no adverse effects on tooth structure but it is always important to follow directions and to be aware of the product’s information.
