Day White ACP 14% Hydrogen Peroxide (Replaces 38% Carbamide Peroxide) 6-Pack Professional Tooth Whitening Gel + 1 Pack Sensitivity Relief Gel - DayWhite

During my last cleaning the dentist said some of my teeth were yellowing and not matching the porcelain cap I have on one of my front teeth, and suggested I do whitening. I have trays that my dentist made for me 10 or so years ago but no longer had the whitening goo. I read a lot of reviews and realize this was a more expensive product compared to others on Amazon, but I previously worked for Philips and know the amount of testing and quality/regulatory they go through for "medical" type products. I am not so sure all of the "no name" products out there (that are much cheaper) have the same level of rigor in meeting FDA regulatory requirements, so I went with this "name brand" since the chemical was going into my own mouth. I have now used three of the six syringes and get about 4 treatments per syringe. I leave them in for about 15 minutes while I am in the shower and drying off before removing the trays and brushing my teeth again. My wife noticed my teeth were visibly whiter (and even said so without prompting) and they now match the color of the porcelain cap I had done about 25 years ago. I am very happy with this product and would buy it again.

My teeth are nice and bright!

I first tired this product at my dentist and wanted more. It works nicely

Works but was a little pricey.

I dont usually leave reviews but i was so satisfied with the results i had to post especially with all the uncertainty when it comes to teeth whitening products. This product mentions 30 minutes of use but I was leaving it on for 1-2 hours. With morning and night sessions for about 2 weeks every day. I think I did an aggressive treatment the initial first day where I used this product for multiple 30 minutes 4/5 times in a day. At first I didn’t think it was working but the results take time of a dedicated routine. Create a teeth mold and ensure you dont get any on the gums or it will burn. There is some teeth sensitivity especially leaving it on for hours but it subsides after a day or so and the results are insane. Check out the shade difference between the top and bottom set of teeth as I was only treating the top set of visible teeth but now I’m thinking they look too contrasting and need to start whitening the bottoms!

Not enough research on safety of higher % s of bleaching agents

I use with a customized tray. They work really well, an almost instant white

I’ve ordered this product twice now! I like the daytime (vs nighttime) version best. I started using this after I completed a zoom treatment from my dentist. I use it about every other week to keep any yellowing or staining of my teeth minimized. I do get compliments from friends at how white my teeth are for age 77! You do need to be mindful of the age of the product being advertised. You can get this info from sellers description or sending a question to seller email.
