Super easy to use! There trays fit perfectly and show results fast. Professional whitening at home with zero mess. My smile is so much brighter! 10/10 ⭐️⭐️⭐️

I love this tooth whitener as it gives me just what I’m looking for in whiteness - natural after 3 trays. It doesn’t cause me to have any sensitivity. A box lasts me a long time because I’m happy with the results after using it for a few days. The fit is great and it’s easy to use. The taste is good too - mint. The packaging is nice and easy to take on the go if needed. The price is right as well. I bought mine at my dentist office. I highly recommend and I’ve tried many. I’m almost 60 years old and I think my teeth look great. Thank you Opalescence!

These whitening trays give a slight whitening effect but nothing drastic. You won’t come out with a sparkling white smile like you see on tv, but your teeth will brighten a bit. The tray fits my teeth and adheres well if you follow instructions. When you place the green tray you have to suck on your teeth to tighten it and remove air like the instructions say. Then the green removes and the film with whitening agent stays. I did not notice sensitivity during of after use. I’m not sure I’d buy these again. I’ll save for the in office guaranteed treatment. Oh also says refrigerate but dentist did not have them in the fridge??
