Whiten Your Teeth at Home

Smiling, which typically feels good, can as well make you feel uncomfortable if your teeth are not that white or your lips are cracked or wrinkled. However a swing of new products and treatments can keep you from wanting to stifle that smile. Here are the tips on applying and selecting stunning and goof-proof shades of cherry lipstick just in time for little-black-dress time of year.

Why do teeth change color?

Blame time and your diet. With age, the enamel on teeth becomes thinner and more transparent, and the inner layer, called dentin, looks darker. Teeth also absorb colored liquids throughout your life, says Jeff Golub-Evans, D.D.S., a cosmetic dentist in New York City. Coffee, tea, cola, and red wine are frequent culprits, along with more tenacious tobacco stains.

How do at-home whiteners work?

Peroxide is the key ingredient in most whiteners. This safe-for-the-mouth bleaching agent forms bubbles on enamel that lift away stains. The higher the concentration of peroxide and the longer you leave it on your teeth, the whiter they well get. The downside: Bleaching molecules can get trapped in nerve passageways, causing increased, though temporary, and tooth sensitivity.

Who is a good candidate?

“At-home whitening is an option for anyone with a healthy mouth who has been to the dentist in the past year,” says Matthew Messina, D.D.S., a consumer adviser for the American Dental Association who practices in Cleveland. Three groups should not do their own whitening: those whose teeth are painfully sensitive to cold; anyone with crowns or fillings on their front teeth (they will not whiten and will end up looking much darker than surrounding teeth); and people whose enamel seems more gray than yellow (due to intrinsic stains from antibiotics like tetracycline taken in childhood). Assuming your dentist has given you the OK; Dr. Golub-Evans says you can assess your whitening potential this way: Hold a piece of white printer paper next to your teeth. If they look yellow, the stains are probably just on the surface — teeth should turn at least a couple of shades lighter with at-home bleaching. If your teeth look grayish, the discoloration likely lies inside the teeth and bleaching will not help much.
