Works well with Essix/Clear retainers
Edit/Edit – It took me almost a month of almost nightly whitening to get to my desired shade, so in total of 6 syringes of 10% carbamide. I’m too lazy to share before/after photos. I’ll stick with buying this product for all maintenance whitenings going forward. I’m going to finish off the last two tubes to see how close to optic piano-key white I can get with 8 syringes.Edit: After an initial 5 nights of whitening my teeth were pretty white, but part of this was due to the teeth being dehydrated (and thus more sensitive). When you take a break for 1-2 days the teeth yellow a bit as the teeth rehydrate. So I started on another regimen, and am now on the 5th night of the second round, with 0.33 in 1 tube out of a total of 4 syringes used over 14 calendar days. Now I want to keep going to see if I can make my teeth look like piano keys.These work very well in your clear retainers. No need to purchase a separate custom whitening tray just for this. Check out the YT videos on how much to actually apply to each tooth– it’s just a small bead needed to the front of each tooth. I don’t express a whole line of gel across the arch, this would be too much product.Also be aware that this is a perishable product. When I received the package, it had a remaining shelf life of 6 months. After, the gel loses efficacy. It doesn’t drop to zero after this date, but just something to note. Amazon comped me an additional 8 syringes at no charge when I asked about the short shelf life.Start with buying 2 packs / 4 tubes of 10% Opalescence carbamide. I bought 4 packs / 8 tubes and there’s no way I can get through all this stuff. I used only 1.75 tubes doing upper and lower arches for 6 nights and got to a very nice white shade, and any more my teeth would start to look like piano keys. I would’ve had to start from a much darker yellow shade in order to actually use up 4 tubes and go through two whole weeks of nightly whitening. And perhaps my teeth are more sensitive than others– Definitely glad I started with 10% carbamide and not anything higher. By the 4th or 5th night I was starting to notice increased sensitivity, despite me having brushed with Sensodyne multiple times a day, every day for over a month prior. I also had braces removed a week ago, and experienced zero sensitivity during that procedure, for reference.

Worth the splurge over the cheaper competitor.
I wasted a lot of money on a cheaper brand you can find on here (rhymes with MyShmile) for it to only whiten my teeth by a hair. This was even with their 35% gel and over week of treatments. It probably whitened by half a shade if at all. I should have just splurged on the Opalescent to begin with, because it would have saved me a lot of time and money. I’m an idiot for not taking a before, but it actually got my teeth noticeable whiter (beyond a doubt) on day 7.One thing I love is that if you have natural vampire fangs like me, whitening them makes them look a little more sharp and pointy. That was a pleasant surprise I wasn’t expecting. I think it’s because the white contrasts with your skin and the shadows in your mouth.Before you buy this, please be aware that you can severely burn your mouth and gums if you aren’t careful with this stuff. Your enamel is strong enough to withstand it, but your flesh isn’t. If you don’t have the custom trays like me, I reccomend using a cheek retractor while painting each individual tooth with the syringe. This will also help to keep saliva away from the teeth/gel as it can deactivate the peroxide somewhat and won’t be as effective. If the gel makes you drool like me and you want to further protect from saliva, tuck some cotton balls under your tongue and beside your back molars to absorb the moisture. Also tuck a towel under your chin like a bib. It’s a learning curve to apply without the tray, but you get used to it.

Easy & Efficient
My teeth have always been dark & I drink coffee & red wine. Whitening at the dentist is very expensive. I use Opalescence 10%, leave it on for 3-4 hours, every month or so. My teeth are slightly sensitive for a few hours. After whitening, my teeth are a natural white, not neon white. I recommend this product.

It Works
I really like this whitening gel, it does work and is what my Dentist uses for touch ups after a whitening treatment for maintenance. That was back in 2002 and my teeth are as white as they were back then. I whiten in the evening right before bed and I leave in for 30 minutes with no sensitivity. I have also done it twice a day (am and pm). I’ll always have this whitening gel on hand.

Take it easy with these!
I have used countless whitening products from Amazon but first time with these. I applied the 35% at one syringe for top and one bottom. Man have I never felt this amount of gum pain from whitening products. I kept it going for probably 30mins with a mantra of “OK so it seems pretty legit just trust its working”. My gums around my teeth per practically white themselves!This might be a superior product but be careful how you apply it. I think next time Ill use less and apply straight to teeth and not as much into the mold.

work great
I have slightly darkened teeth from Tetracycline as a child. This teeth whitening gel is amazing. My teeth have never been so white. I also bought the trays that can conform to my teeth to keep the gel in place.

Must try!
My forever favorite #1 teeth whitening brand. I’ve yet to find another brand that gives you these same results. I’ve been using Opalescenes for 21 years and I get so many compliments on my teeth.

The package didnât include all the items described. The return cost was four times higher than what they covered.

Worked very well for me

The product works as advertised. I was recommended this product by my dentist and discovered that it was much cheaper on Amazon than other platforms. It was also more than 4 times cheaper than from my dental clinic.
