whitening my teeth?

what is the best whitening toothpaste you guys have used?
--------------------
Original Crest whitening is my personal favorite as far as toothpastes go, but keep in mind toothpaste can only do so much. If you want really white teeth, professional trays are the way to go with a kit from your dental professional. I used to whiten teeth for a living and my favorite way to whiten is with a carbomide peroxide solution that a patient sleeps in overnight for around a week. As long as a patient has no crowns or fillings in the front and they aren't sensitive I usually prescribe a 20% formula, and Ultradent's brand from the Opalescence line of formulas are my faves. Laser whitening and other methods I am still skeptical about (though I have done them on patients) but the week-long program gets great results and don't ruin or remove any of the natural enamel on teeth. Whitening toothpastes use micro abrasives and small amounts of peroxide and will remove certain "surface stains" but can't touch the older stains embedded in the tubules of dental enamel sadly...I am (unfortunately) a heavy smoker myself and use a regimen of professional whitening with custom trays and carbomide peroxide and whitening toothpaste to make sure my teeth don't restain, with a one night touch up procedure every year and my tetth (thankfully) are sparkly white and nobody notices I smoke. Good luck with your pursuit of a whiter smile! :)
