Opalescence Go 15- Prefilled Teeth Whitening Trays – 15% Hydrogen Peroxide – (10 Treatments) Made by Ultradent Products. Teeth Whitening Kit -Mint – 5194-1

These whitening products are the only ones I will use.
Being using this whitening trays for over a year and is the only product that I will use. The trays are very easy to apply and when done they leave my teeth very bright as you have to use per instructions. Very satisfied with the results.

The best whitening tray
I enjoy drinking coffee, so I was very interested in teeth whitening. I was recommended this product by my dentist because it is effective. I had never used a whitening product before, so I didn’t have high expectations.One box contains 10 trays, and I used it consistently for 30 minutes every day. I was able to notice the change in the color of my teeth with just 10 trays.Pros1. Excellent performance. It is amazing that you can have white teeth in just 10 days with 10 trays.2. Very convenient to use. Each tray for the upper and lower teeth is individually packaged, so you can use one at a time.3. The wax inside the tray has a mint flavor, so you can use it without feeling uncomfortable.Cons1. It is more expensive than strip products. However, it is acceptable because it is more effective. If you subscribe, you can purchase it at a discount of about 10% compared to the regular price.If I have someone who is concerned about tooth discoloration, I will strongly recommend this product.

Not as strong, mild
These do not seem as strong as the Crest whitening strips. With those I tend to notice an increase in whiteness very rapidly, and it is quite drastic, but these have been kind of disappointing overall. The nice thing is that I had virtually no sensitivity with them. There is gel inside the trays that is all at the bottom so perhaps it doesnt fully cover the teeth. The flavor is great! Overall not worth it for the price since the crest strips have worked much better.

Works well – makes my teeth ache a little after
I have bought this product a few times because I believe it works better than crest whitening strips.The first time I got it was from the dentist and it actually bleached a couple parts of my gums which is normal and went away but the two times I’ve bought it from Amazon it didn’t do that. I don’t know if that has anything to do with the quality but either way it does work. I will say the dentist sold it to me for $400 for the same amount and strength as the $87 one on Amazon.It also does make my teeth have a dull ache for the next day or two after using it just once or twice so I can’t go the full 10 days in a row.Overall I like the product and use it to brighten my teeth back up when I feel like they’re getting dull.

Great product! Dentist sell this particular brand, at a higher cost unfortunately! I have had trouble with Amazon restocking this product. I recently purchased Crest 3D white strip, which don’t work quite as well! Please ensure Opalescence Go are alway in stock!

Good product. Does the job
