What Are The Safety Concerns Using Teeth Whitening Strips

Teeth whitening strips are not regulated by the Food and Drug Administration, unlike tray systems. The active whitening agent is hydrogen peroxide in teeth whitening strips, whereas the tray system uses carbamide peroxide. Although hydrogen peroxide is much harsher than carbamide, there is no evidence that it can cause damage to your teeth when used correctly. Even though the government doesn’t regulate teeth whitening kits, there are studies done by individual companies to determine the efficacy and safety concerns that might be relevant for their products.

Bleaching Agents

Hydrogen peroxide is a bleaching agent that can cause tooth sensitivity and gum irritation. You have to check individual studies for name brand teeth whitening strips to figure out what the safety concerns might be for that product. The studies that are done do check for changes in the enamel to makes sure they are safe to use. Since popular brands are sure to have a study, one should try the major brand first and avoid any generic product that hasn’t been tested by anyone.

Prior Dental Work

One item that is important when deciding to use whitening strips is what type of dental work you might already have had done. There are studies that indicate that using the strips can cause white dental fillings to have microscopic roughness. Whether that can later cause a deterioration of your white dental work is probably dependent on the how long you use the product and how heavy the concentration of hydrogen peroxide, as well as the quality of your dental work. You also may not see the same level of brightening on white dental work as you do with the natural tooth material. There are also some studies that indicate that hydrogen peroxide can cause an elevated release rate of mercury from metal fillings. This is usually noticed more in newer fillings than one that have been well set for many years. Check with your dentist to see how safe it is to use a whitening product with any existing dental work first.
