How long do i leave Crest Whitestrips supreme on? I was given one set of crest whitestrips in a giftbag. and there is no directions on them. So what do i do? and, do they even work?

And its 9.5% peroxide and I leave mine in for an hour or longer it gets them whiter and they stay whiter longer. The only draw back is my teeth become sentisve when I take my treys out, I mean I can suck in air and it will send a chill down my spine, but I don;t think theres are nearly that strong. So you can leave them on for I would say at least 45minues to 1 hour to see how that have progressed and if there not as white and your teeth aren’t hurting put them back on for a little longer.

Hope this helps!!! Goood lUck"

My teeth hurt worse than anything I have ever felt in my life after Crest Whitestrips Supreme, any tips? Day 1: Two strips top and bottom for the time directed, 30 minutes each. My teeth ached the entire night and my gums were swollen. I know the bleach is stronger than the whitestrips you can buy in the store (Supreme can only be purchased from a dentist), but this kills! I don’t know if I will make it the 21 days that the kit offeres with this stronger bleach.

Any tips besides sensitive tooth toothpaste and Act mouthwash to fill in areas of my teeth?

On the plus side, there are noticible results after just that one day with this stronger kit! Normallly I don’t see results like this until day 3 of the Premium strips. I only do these once a year by the way just to brighten up my smile a bit, and I see my dentist twice a year for cleanings :)

The directions say that I can skip a couple of applications but that I should use all the strips in as close to 21 days as possible… so stopping until the pain goes away or wearing them every other day really won’t work.

queen replied: "You could try asking your dentist for fluoride gel. It might be stronger than Act. I know what you mean though, it hurts! Definitely try using them every other day."

Tina N replied: "i would stop using them. I have crest whitestrips, and they bothered my teeth a bit but they didn’t swell my gums. I know crest offers a hotline for the whitestrips, and if you call who knows, you might be able to get a refund while your at it. But be careful, you could have an allergic reaction."

sylvia a replied: "as they say.. no pain – no gain. but see the dentist for advice just to make sure that the bleach is not too strong for ur teeth, or too irritating on ur gums."
