Opalescence New Opal Go - (7 Treatments) Gentle Prefilled Teeth Whitening Trays w/Sensivity Toothpaste 4.7 Oz - Hydrogen Peroxide - Cool Mint - Made by Ultradent. 5761-5526-1

I just finished the 7-day Opal Gentle Mint whitening tray kit (which comes with a toothpaste), and I’m genuinely impressed! I have really sensitive teeth, so I was a little nervous to try something new—especially after painful experiences with Crest whitening products that left my teeth hurting for days. After reading another review, I decided to brush with the included sensitive toothpaste before and after each tray application—and it made a huge difference. I only experienced very minor sensitivity throughout the whole week. The whitening results weren’t drastically dramatic after 7 days, but honestly, I prefer a gradual change that doesn’t come with pain. I’d much rather take it slow than damage my enamel or suffer through days of discomfort. I already ordered another box and plan to use these once a month to maintain the momentum and gently work toward my ideal shade of white. Highly recommend for anyone with sensitivity who still wants to brighten their smile!

I'd rather use these, my wife paid the Big buck for forms and the product, (from the same co) is overall more expensive. These clean my teeth just fine and the treatment is a short duration(not over night) which suits me just fine.

Was so excited to try this but got it last night and tried the first tray and nothing happened. Crest whitening strips work immediately for me so I expected this brand with a great reputation to work even better but am extremely disappointed to report that they don’t work at all! I doubt I can return them with one tray missing but will try calling their customer service to see since there’s really no point using the rest.

I bought these because the hygienist at my dentist office said that these would be good. Well I like the toothpaste and the little trays that they came with didn’t seem to stay together all that well and I never ever seem to notice a difference in whitening . Crest advance white strips work best.

These whitening trays worked well and I had zero sensitivity issues with them. Would both recommend and purchase again. Also like the toothpaste.
