What is the best toothpaste to whiten your teeth?

PLEASE DONT SAY CREST WHITESTRIPS.
--------------------
Store shelves are filled with so-called teeth-whitening toothpastes, which usually cost more than regular toothpaste. However, researchers say whitening toothpastes are less than impressive and that you can achieve the same result by brushing for the recommended two minutes with regular toothpaste. This is because peroxide and time are both needed to have a whitening effect on teeth. Many whitening toothpastes only contain that do contain peroxide aren't in contact with your teeth long enough to have much of an effect. Researchers say you're better off brushing well with ordinary toothpaste and putting those extra dollars towards a true bleaching product I found that professional teeth whitening -- though expensive -- is the most effective and convenient way to brighten your smile. The kit itself is only $25 but you would need a dentist to do the bleaching for you. The most modern ones don't even need curing light anymore and according to my bleaching patients, there is no pain and we finish the procedure in less than 30 mins.
