yeah it's all about contact time and concentration. That's why the whitening gums are such junk. The stuff I have stays in for at least one hour and has a concentration of whitener far higher than what you're allowed to sell on store shelves. I can literally see my teeth whiter after each time (actually what I see is a kind of chalky coloration on my incisors, but that fades shortly after - although you'll never get that effect for regular whitening products).Originally posted by: JMWarren
Yeah, I worked in a pharmacy for a number of years and have alot of experience with these products. Crest White Strips are a decent product, with good results. Natural White products often provide similar or better results at a lower cost. In addition i recommend picking up some "Sensodyne Whitening" to help with the sensitivity that often occurs with all of these products. As for the toothpastes like Rembrant, they don't work overly well, mainly due to contact time.

Her dentist sucks donkeys. I paid $190 incl tax for my first kit. It included 10 colgate syringes (colgate was the brand for this stuff) and my molding. I think they gave a discount on the molding, but I know I can get new trays made for no more than $50 if I need. It only takes them 5-10 min and costs little in materials. I can buy extra syringes (good for about 5 full applications, since the spare syringes are discus dental as opposed to colgate and you're able to use them more sparingly) for $16/piece. I did the first 10 syringes and noticed good gains (I think around 11% active ingredient). I then did two of the 16% syringes and was getting better. I'm now 2/5 through a 22% syringe (highest they make), and by the end of this I expect I'll be all but finished my whitening, then touch up every several months.Originally posted by: xSauronx

my sister got trays fit to her from a dentist
$400 for them i think, or something crazy like that (mold and whitener)
then, a couple months ago, her tooth broke and she got a crown (~$800)
which didnt fit the mold
the lady at the dentists office (secretary i guess) told her shed have to buy a new mold for another few hundred bucks....my sister keeps arguing that the crown, for $800, should match the tooth it replaced
ive told her since she spent $400 on a mold, she could have bought dozens of those whiteners in a store...bleh to her
Colgate's simply white I think? I tried it and didn't care for it. Much like crest's commercial for a similar product says, the colgate just comes off your teeth very quickly.Originally posted by: yamahaXS
I used the crap you brush onto your teeth and it worked okay, but was a pain to use because you can't close your mouth (or drink beer) for 15 minutes after application.
