If routine dental hygiene isn't enough, do away with food and drinks that can potentially yellow your teeth. If you're a wine-lover, switch to Chardonnays and Sauvignon Blancs. If you covet cola, try paler versions. As for cigarettes, that habit should have been curbed long ago.
Product treatments: Abstaining from dark or colorful substances (like coffee, tea and wine) may slow the yellowing process, but it won't turn your teeth white. Fortunately, there are many good bleaching solutions, offered both in-home and at dentists' offices.
First, you will need to choose between in-office and home solutions. Home whitening systems, like Crest Whitestrips, cost less than $100. The two week treatment is applied for 30 minute intervals twice daily.
Your dentist can prescribe Crest Whitestrips Supreme, which contains 14% hydrogen peroxide, a step up from the standard 6- 10% in home bleaching kits. A dentist can also opt to perform an in-office bleaching procedure, complete with follow-up trays molded to your teeth, that contains a higher concentration of hydrogen peroxide for more whitening action.
Of course, don't overlook the value of the traditional toothbrush and floss. Brushing and flossing after every meal can dramatically cut back on tooth stains.
