Depends. How dark are the teeth? For mild discoloration, or for someone who wants minor color change, try crest whitestrips or cao sheerwhite!. But if you want a moderate or major color change, see your dentist. I have had great success with 1 or 2 in- office zoom! led treatment and dispense custom fit home trays with either 10%, 16% or 22% nitewhite or 14% daywhite. Or kor whitening system.
Whitening. Custom made trays from your dentist is recommended with solutions of the appropriate percentage of carbamine peroxide. Otherwise the over the counter crest whitening stripes work but can be difficult to position and stay in position.
Talk to your dentist. It is best to talk to your dentist about whitening your teeth so you do it safely and successfully. There are many systems that can work. Some of the ones you see in the stores and online can actually hurt your teeth. Avoid smoking, coffee, tea, red wines , grape juice, blueberries and other dark foods and drinks that can stain your teeth. Good brushing and flossing helps keep your teeth whiter.
