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

My daughter bought this product (Opalescence Go 15% Hydrogen Peroxide) from a dentist who probably charged her double what I paid on Amazon. I bought these during July's Amazon Prime sale and I plan to use them to prepare for my 40th high school reunion soon. When I tried these (daughter gave me like 4 trays when she lived with us) I was AMAZED at how well they worked. My teeth whitened after using just ONCE and it was super easy and convenient. I also bought the other version of Opalescence and will use those intermittenly as well. My teeth can be sensitive from time to time but I have not had issues using this product at all. Good stuff, highly recommend!

I was skeptical about this product but it came highly recommended from a few friends. My teeth were pretty stained from years of coffee and tea drinking. My teeth are sensitive so I had to space the treatments out longer than the 10 days. But there is forsure definitely a noticeable difference! I will be buying again to see if I can get them whiter. 10 out of 10 would recommended.

Ive used these every 3 days since I got them. I’ve went through half the box and my teeth are tremendously whiter

I used this product one time so far, and even that limited amount brightened my teeth. I’m impressed.

Love this product, noticeable different in my teeth! Had made a huge difference in my smile! Only recommendation, don't leave on longer than recommended time, otherwise you will have sore gums for a few days. Follow instructions.

I know your second guessing because of the price because so was I, but I went ahead and purchased it and I’m glad I did. It works! You will notice a slight difference after even the first use but you will notice a huge difference if you stay consistent and use it the proper way and avoid foods and drinks that will stain your teeth. THAT IS THE KEY.

I think I received an out of date product, even though it shows an expiration date of 12/31/2025. The whitening gel does not lift off the trays when inserted like it's supposed to do. I always get one free set of trays from my dentist of the same product , and it easily applies as it should.I didn't use these every day, but every few weeks when I felt like my teeth weren't looking bright. Results were okay.

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.
