Opalescence is the best teeth whitening product I have found. I would buy this directly from my dentist up until he retired. You get the best results from custom made trays, however, using generic whitening strips with the Opalescence gel gives good results as well. Badly stained teeth may need daily whitening to begin, but once a week will keep them maintained. The only downside is that it's a little pricey. I recommend this product. Read more

The product works! The sellers are aware it will make your gum and teeth sensitive. in the box there is instructions of how to lower teeth sensitivity when applying the gel. I had the gel on for 2-4 hours and I can see results already. I suggest this but know it will make your teeth tingle. tray is not included. I used my retainer as a tray Read more

I do notice that my teeth are whiter. My teeth didn't start out extremely yellow so I didn't see much of a difference. I am hoping that with time it will give me that bright white look. So far it hasn't and I used a whole tube. It also did not make my teeth sensitive which I really appreciated. Read more

One full syringe fills both of my trays. Due to strength and sensitivity, I can only tolerate 2 hours at a time. This means I have to use more, more frequently. It does whiten well. Read more

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! Read more

I’ve used tons of whitening products, but this is BY FAR the best. It noticeably whitens my teeth in just half an hour - and get me to my desired whiteness in just a few uses. Be aware: this gel is super strong, so you don’t want to leave it on too long (it will make your teeth sensitive) & try no to get too much on your gums (it burns and can leave them temporarily bleached). With all that said, this is definitely the most effective whitening gel out there. It is used in dentists offices. Read more
