Opalescence Go 10% - Prefilled Teeth Whitening Trays Kit (10 Treatments) - 10% Hydrogen Peroxide - Mint Made by Ultradent Products. Go Teeth Whitening Kit -Mint- GO10-5193-1

Works like it is supposed to. Husband is the one using them . He is happy!

I decided to focus a little more on self-care this year, and whitening my teeth was high on the list. As a former smoker and someone who still drinks a lot of coffee and tea, my teeth were pretty stained and yellow, so I ordered this whitening kit in the 10% strength since I do have sensitive teeth. I’m just finishing up my last treatment from this round, and I can definitely see a noticeable difference in how many shades whiter my teeth are. They’re not perfect yet, but the improvement is obvious enough that I already ordered another round to keep going. Because of my sensitivity, I use it every other day instead of daily. As long as I space it out like that, I have little to no sensitivity, which has been a huge relief. I also appreciate that this is melon flavored. I can’t strongly taste it, but I can tell it’s not mint. Mint tends to really irritate and burn my gums, so I try to avoid it whenever possible. Having a non-mint option is a big plus for me. I’m really excited to keep going and see how much more my smile improves with the next round.

Work great. If your teeth are sensitive, the 10% are easier to tolerate.

I've used these whitening trays for years, and they used to work consistently and reliability. Over the past couple years, I've gotten more and more bad trays - where the inner piece won't release from the tray itself. I've gotten to the point where, if that happens, I just leave the green tray in place as well. Not very comfortable, but, short of having to go through the hassle of returning the product, then waiting for a new one, it just seems easier. The manufacturer has a lot of QC to work on! But they do whiten nicely. UPDATE: I've now finished the set of 10 trays. Of the 10 sets, only ONE set actually released as they were designed to do. Therefore, in order to have the inner trays remain in their proper place, I had to leave the green trays in the entire time. Not very comfortable. The whitening system still worked, but they need to fix this defect whereby the inner white tray rarely releases from the green. Interestingly, before inserting the trays, I'd test to see if the white tray readily lifts from the green. It does. So I'm at a loss why these no longer perform as they had for years and years.

Mia dientes aclararon como 5 tonos, te deja un blanco muy natural, pedí el que viene al 10% porque mis diente son muy sensibles y me funcionó me perfecto

I was recommended this product by a coworker who use to a hygienist. She swore by this brand. And did her whole family use it. So I have it a try. I will say that I feel too it whitened my teeth a bit (forgot to take before and after), however I feel you need me than the 10 treatments. They were really easy to use and I usually did it first thing in the morning before brushing my teeth for 30 mins. The instructions on my I think were backwards, starting 10 for better whitening and 15 or more for less whitening. Must've been a misprint. Either way keep them on for at least 10 mins and before brushing b/c you'll have to brush the stiff of again anyway, so might as well do it before. I gave this 3 stars b/c 2 of my trays sets were damaged. One where I had to totally throw it away and 2nd (in photo) where it didn't fit properly. So I was a bit disappoint that of of 10 only 8 worked the best. I would suggest getting tests that cut your teeth individually, and they just by the tubs of the whitening gel. The coworker who recommend this product also said they is probably the best way b/c then the get is set right where it needs to be for best whitening results. I don't think this is a bad product and would recommend it, however for the price ALL the trays need to work.

This is great

I am a dental hygienist and I am always recommending Opalescence Go to patients. The only downside is the sensitivity, I always recommend using a toothpaste for sensitivity 2 weeks before and after the treatments.

good for quick touchup
