Opalescence 35% CP Mint - Gel Syringes Teeth Whitening - Refill Kit (2 Packs / 4 Syringes Total) Carbamide Peroxide Gel. Made by Ultradent. Tooth Whitening Refill Syringes 5197-2

This brand never disappoints! I finally finished with my Invisalign treatments and now have to wear retainers when I go to bed. So whenever I need a little whitening I use these gels and they work! Beware that if you do have sensitive teeth like me you might have to do less than 30 minutes. Taste of the gel is not very good but I can overlook it to get the results I want.

After completing my orthodontic treatment, the orthodontist “gave” me a Peroxide-based 20% ten-day treatment system. But I didn’t get the results I wanted. So I called my dentist to see what they had, and they had this exact same product, but they would create the liners too for $540! It was the same treatment, but I already had the liners. So for $30, this was a no brainer.After a few treatments, I can see the biggest difference. I may just use a few more, but let’s face it, I’m not going with the “Ross” look (from Friends). My teeth have been more sensitive throughout my two+ year orthodontist process, but I haven’t had any sensitivities since completing the process. The only caution that I would give (like the others) is it will bring the gums. So here’s what I’ve done:Apply a very small bead in the center-front of each tooth imprint of the dental trays/liners. The line seems to be too much. Add a coating of vasoline around your gums with either your finger or a q-tip. Then apply. If you do feel it burning your gums, simply pull off, and use a soft- white toothbrush on the area of the liners/trays to remove the gel from the are closest to your gums. Simple. I was able to tolerate it for the full 30 minutes. Would highly recommend, but definitely use a very small amount and use with caution! I’m so happy with my newly straightened, whitened teeth! In the words of Buddy the Elf, smiling’s my favorite! Now I can smile with confidence!

A much much much better deal than purchasing it from my dentist and this stuff is a rockstar! My teeth have never been whiter! I started out using this product with a lower dosage and then moved up to this, and I would suggest doing the same as it can be kind of harsh on your gums. Don’t let that stop you though this stuff is amazing.

These are Terrific, at 35% and a good buy. My sister is a dental hygenist and she told me about these online at Amazon. Better whitening and better price than at my dentist office that only offers 10% whitening @$40 for 2 :-(... I recommend.

Works well! It’s super strong and burnt my gums, it hurt and turned them white which was scary! I came up with the idea to put the gel on a q-tip, put it on my teeth and then I insert the retainer that way it never touches my gums, works perfectly!

I use these in a dental tray make by the dentist. My teeth are so white from this whitener. I use it as needed after my initial whitening use. Great buy and worth the money.

Second time buying this. Love it, works great. I would suggest to not leave it on for more than 30-45 minutes instead of 60. This strength one hour is pushing it. You'll still have great results. Do it for a week.

I have been using this product for years. Great does all they promised.
