<p>Just be careful - I know of kids and parents who have bleached so much their teeth are now sort of bluish. Moderation in all things. Pure white isn’t really that natural looking when you think about it.</p>
<p>Agree mammall - I have seen teeth that have a strange glow about them. I did it once and then every few years, do a tray of the lower percentage gel for a special occasion.</p>
<p>I have used Crest Whitestrips myself and they have worked great. As others have said, it does cause your teeth to become sensitive to the hot/cold, so be prepared for that. </p>
<p>It is also a little uncomfortable for me, and I had to get used to having weird tasting (I know you’re not supposed to taste it, but some of it gushed out) film over my teeth. </p>
<p>But… it does work, for $35 :)</p>
<p>My dentist warned that yellow-tinged teeth are less likely to be successfully whitened than those that are grayish or brownish. I thought it was worth a shot and I used the dentist-supplied trays (which were costly and annoying) on my yellow-ish teeth and found little improvement when all was said and done. I believe are very different results for teeth that are naturally a particular color vs. those that are stained. I wish the whole whitening craze had never gotten started–now people are unhappy with teeth that would have been perfectly acceptable 10 years ago, and everyone ends up spending money on a new “problem”.</p>
<p>If you use the Crest Whitestrips for 10 days, do you have to wait a certain amount of time before you use them for another 10 days? This is for slightly yellowish teeth, not teeth that are already bright white.</p>
<p>My D did the Zoom 2 technique at the dentist 3 weeks ago with terrific, natural results. Her teeth were varying shades of yellow, and now they are a more natural shade of white, not blinding white. She had no issues with uber-sensitivity or pain, though she was warned by the dentist that those might be possible side effects. We were satisfied.</p>
<p>My dental hygenist gave me a good tip–she said that after whitening, teeth are especially porous. She said you should avoid drinking coffee, cola or other dark colored drinks for a few hours the day you whiten (ideally, the whole day). I suggested flouride rinse after, to strengthen the teeth, and she agreed that this was a good idea, but to try to find a clear-colored flouride rinse because the colored ones can impact the color of the newly-whitened, porous teeth.</p>
<p>Hope this helps!</p>

<p>I had the same experience as Jolynne described - dentist said no colored things for 2-3 days. I had tetracyclin antibiotics as a child, so my teeth were hopelessly yellow. Or I thought they were… Zoom 2 worked wonders. I would not recommend the procedure to anyone who is a whimp about sensitive teeth, though (my H is one of the people who should just forget about Zoom 2). My teeth became slightly more sensitive towards cold foods and sweets right after the procedure, but regular brushing with a prescription-strenghth fluoride toothpaste helped.</p>
