Hello y'all !
I just received the Crest 3D White Professional Effects and I'm going to use them tonight but I'm so scared of the tooth sensitivity cause my teeth are quite sensitive ..
They are not yellow or anything but I wanted to try it...
What is your experience with them??? were your teeth whiter? and what about the sensitivity ???

Wondering the same

If you already have sensitive teeth I'd recommend waiting several days between treatments. Depending on the kind you use they can make your teeth ache and super sensitive for a while. The pain does go away, though. It shouldn't do any permanent damage.

You probably won't notice any changes in whiteness until you've tried a couple treatments.

Pretty Hurts.

ohh... okay thanks !
I let y'all know tonight if my teeth are sensitive or ache...

I tried those before and they HURT!!!!

I wouldn't recommend putting them on before going to bed. I made that mistake and I couldn't sleep the entire night due to the ache.

my teeth looked polished after taking them off... possibly a few shades whiter but definitely not as white as I would've liked them to be. (my teeth aren't yellow, but they aren't paper white either )

they stay in place pretty well and do a nice job of forming to your teeth (they're actually kind of hard to get off), but they can definitely cause sensitivity. I use a sensitivity toothpaste and make sure that I only leave them on for 15 or 30 minutes (I forget which). oh, and I also only use them like every couple of days. that seems to help with sensitivity.

DO NOT LEAVE THEM ON LONGER THAN YOU'RE SUPPOSED TO (ie. overnight). you might get faster results, but it's not safe for your enamel.

Thaaanks y'all !!!!
I had them !!

So Day 1 - I feel no pain, sensitivity or anything...my teeth are not whiter but I didn't expect anything after the first usage.... (I should see results after the 3 days)
I let y'all know !

used it twice. a year in between. Just a tip: use only for the exact time recommended. otherwise , it will hurt like hell.

Yeah I had them exactly 30 minutes..

dont

I've been using them for a week and they work really well imo. I use it together with Opalscence toothpaste, activated charcoal tablets and home bleaching sets. My teeth have become so white !!

The strips do make your teeth sensitive over a few days though and the peroxide can sting your gums really bad so make sure you align the strips so it's not touching the gums.
