FAQs What ingredients are in tooth whitening? Depending on the method chosen to whiten your teeth, the ingredients may differ. The active agent that actually whitens teeth is either 1) carbamide peroxide or 2) hydrogen peroxide. A thickening agent of glycerin, glycol, or glycerol helps to contain the whitening agent to stay on your teeth instead of spilling onto unintended areas such as the gums. All of the thickening agents have a drying effect on the teeth. The drying effect may lead to discomfort such as temperature sensitivity but will not inhibit the health of your teeth. To counteract the drying effect of thickening agents, some thickening agents are water-based which work to re-hydrate the teeth. Since tooth whitening may lead to sensitivity, some methods, but not all, may contain desensitizing agents of fluoride, potassium nitrate, or chitosan. In addition, some brands have flavoring additives to improve the whitening experience. Will teeth whitening work for everyone? Teeth whitening will not whiten crowns, veneers, or fillings. Teeth stained with tetracycline may take longer than normal to whiten and the result may not be as drastic. In addition, moderate to heavy use of products such as coffee, tea, red wine, and tobacco may eliminate any effects of tooth whitening. Furthermore, since teeth are more porous for about three days after bleaching and thus are more susceptible to teeth staining products, patients should refrain from those products during bleaching. What causes teeth sensitivity? The main disadvantage of teeth whitening is short term temperature sensitivity. As mentioned above, thickening agents in whitening gels may dehydrate the teeth and as a result, the teeth may be sensitive to thermal changes in the oral environment. In addition, some patients just have sensitive teeth. Studies have shown that when most patients complain of teeth sensitivity after whitening, the main reason is due to sore gums and not teeth sensitivity. It may be difficult for some patients to differentiate between teeth sensitivity and gum sensitivity. However, with careful patient screening, use of new generation whitening materials, and properly fabricated whitening trays, the incidents of dental sensitivity have decreased dramatically. What are the common reasons for teeth sensitivity? Poor fitting whitening tray may irritate the gums and allow the whitening gel to migrate off the teeth and onto the gums. Wearing a tray for several hours increases the time for the whitening gel to migrate to the margins of the gums and thus causing irritation of the gums. Wearing a tray for several hours at a time increases the dehydration of teeth. Too much whitening gel in the trays causing an overflow onto the gums. No desensitizers in the bleaching gel.
