Most of us here drink black tea the most.
Tea stains teeth over time so here are some tips on how to keep your teeth from staining or how to get rid of the stains and some warnings about whitening.
Be wise about beverages. You know how coffee can stain a porcelain cup. It, along with tea and colas, does the same thing to your teeth. When you do indulge in staining beverages, do so in one or two sittings rather than sipping such drinks throughout the day. And brush after drinking them.
Use a straw. Okay, you may not want to try this with hot coffee, but sipping iced tea, cola, and fruit juices through a plastic straw will reduce your teeth's exposure to these staining beverages.
Use stain-removing toothpastes with caution. So-called smokers' toothpastes, designed to scrub away tobacco, coffee, and other stains on the teeth, are generally abrasive (unlike most of the newer "whitening" products, discussed in the next section) and should be avoided in all but the most serious cases of stained teeth. Even then, dentists usually recommend using these products no more than two or three times a week. You may want to check with your dentist before you try one of these.
Get a "cosmetic cleaning." If your teeth stain easily, call your dentist for a cosmetic cleaning between checkups. The procedure takes about 20 minutes and costs about half the price of a regular cleaning. (It is not, however, meant to take the place of regular checkups.)
Don't get creative. Brushing with baking soda can scratch composite resins and porcelain veneers (which are used to make crowns and other types of tooth restorations). Scratches on these materials pick up stains more readily. Other home treatments that can spoil smiles include dental picks and applications of chlorine bleach.
