What Makes Teeth Look Whiter?

When it comes to the natural shade of your teeth, a variety of genetic and lifestyle-based factors can directly impact their color. “Tooth color is a result of both the natural structure of teeth and the presence of stains on teeth. Stains typically come from external sources such as foods, drinks such as tea, coffee, and wine, tobacco use, and tartar,” Venda Maloney, Oral Care Early Research Director at Colgate-Palmolive, explains. “Over time, tooth color becomes darker due to continued exposure to stains as well as enamel wear.” A couple common chemicals used to whiten teeth include carbamide peroxide and hydrogen peroxide, which work in similar ways. Carbamide peroxide lasts longer when its in active form, but needs to be stronger than hydrogen peroxide to work well.

Are Teeth Whiteners Safe to Use?

Each ingredient is deemed safe and effective to use at lower percentages, but at higher percentages, they can cause gum tissue damage or an increase rate of tooth sensitivity.

Can I Whiten My Teeth If They’re Sensitive?

“One red flag to keep in mind with teeth whitening is increased sensitivity that doesn’t diminish after a 48-hour period,” adds Lewis. “Another is gum irritation, as some people will have increased sensitivity, and will need to take more time in between whitening.” According to experts, whitening can temporarily dry out your teeth, which is ultimately what causes their sensitivity. As the teeth rehydrates, the sensitivity diminishes. “You should always visit a dentist prior to teeth whitening, because whitening in the presence of tooth decay is not advised,” continues Lewis. “If you get a clean bill of health from your dentist and you have straight teeth, trying over-the-counter teeth whitening is a great option. If you don’t get the results, you want form those kits you should visit your dentist for stronger concentrations that can be applied safely.”
