35%, 4 Syringes : Opalescence Teeth Whitening Gel Mint with 3 GreenDot Teeth Trays (35, 4 Syringes)

This is not a scam. This is not a fake product. This is REAL teeth whitener. It’s stronger than the Crest 3D White drugstore bullshit strips, so yeah, it’s gonna burn a little. It’s strong. Isn’t that why you’re looking it up? You want something that works better than the wimpy little cellophane strips from Crest, don’t you? THIS IS IT, people. It’s peroxide, so yes, it will cause your gums to whiten for a little while (pigmentation comes back, of course). That’s what peroxide does. It bleaches. Yeah, it’ll burn. These are strong chemicals. This is not your grandma’s homemade, all natural, vegan white strips. This is the stuff dentists use (I know this because I’ve gotten this from a dentist before).So go ahead and listen to all the rest of the idiots who say this product is harmful, a scam, what have you... but it works, it’s reasonably priced, and it’s not for wimps. Buy it if you want white teeth. Don’t buy it if you’re over-sensitive.

I never write reviews...but this product is horrible! Do NOT buy this product. I used it for about 15 minutes and my gums started burning. I immediately washed the product off and my gums were sore and red. I went to my dentist the next day and he said I had extensive gum trauma/damage. Two days later, they are purple and have white spots. They are trying to heal, but I can barley eat. They hurt so bad. Do yourself a favor and try something else! It's not worth the pain, trust me.

I bought this product for myself. I am a former smoker. I also drink coffee and tea daily. I was amazed how fast it worked! After 4 treatments of 30 minutes each, my teeth were noticeably whiter. I didn’t have any problems with stinging or sensitivity. I do use this product sparingly though and am careful not to let it set on my gums!

If you have access to such option from your dentist, I highly recommend you get a tray made by a professional. I chose to purchase this option for Opalescence because it came with the three trays. I figured I was going to mess up at least once, but this type of tray was just not cooperative for me. It often ended up getting hot enough to the surface, but not hot enough through the core, so it never formed around my teeth like some instructional videos have shown.Another review mentioned the burn, and it's absolutely worth repeating. It's also why I highly recommend professionally made trays, since a properly fitting tray will make it easier to avoid the gel touching your gum and only stay at your teeth level.As for the whitener itself, it's OK at best. It was honestly all in all a lot of hassle for minimal result. YMMV with something like this since everyone's teeth is different, but I feel like I could have gotten similar result with a different whitening solution without as nearly as much hassle.

Amazing! I wasnt expecting much when I got these but was shocked by ho well it worked. Took five or six uses to get highly visible results. TIP: line your gum line with vaseline or else it by hurt your gums. But even if your gums d get effected the bun gradually goes away and you get used to it by the third or fourth use. Your gums may look white but they will go back to normal within 20 minutes. Ways the saying "pain is beauty"? Well its true but this will give you visibly whiter teeth if you want it offer through it nd hou will get used to it
