Opalescence Go 15 - Prefilled Teeth Whitening Trays - 15% Hydrogen Peroxide - (10 Treatments) Made by Ultradent Products. Teeth Whitening Kit -Mint - Includes 2Chill Toothbrush 5194-1T

This kit it worth the money, I saw a dental hygienist suggest these on TikTok and her teeth were super white. I’d been using the crest 3d whitening strips and those work but I feel like you need to use those pretty often and they make your teeth sensitive. I will say these do make your gums and teeth sensitive BUT after the second application (I waited about 2 weeks before the second application) my teeth were noticeably whiter and the sensitivity went away after a few days. With whitening strips is just about impossible to get away from gum irritation and teeth sensitivity but if the whitening is super affective then the option where you use them less frequently is best overall. This kit is high quality, the treys for application confused me at first but I get it they make sure you put them in the right spot and they stick very well. The tooth paste for after is nice and makes sense. If you want genuinely whiter teeth and you don’t want to have to use several application this is the right kit. Worth the money for sure

After reviewing other comments I was worried that this would hurt my gums, or cause uneven whitening. Alas, it worked well! Easy to use, gentle whitening that looks natural and seems to last for a good while. Recommend

The Opalescence Go 15% Mint prefilled teeth whitening trays are incredibly convenient and easy to use, and they delivered great results for me. Super Convenient: The prefilled trays are a huge plus—no syringes, no mess, and no guessing how much gel to use. I just open a pack, pop them in, and go. They fit comfortably and stay in place, which makes whitening at home simple and stress-free. Comfort & Taste: The mint flavor is mild and pleasant, and the trays are comfortable to wear during the treatment time. I didn’t experience much sensitivity, which is always a concern with whitening products. Noticeable Results: After a few uses, I could already see my teeth looking brighter and cleaner. It’s a great option for quick touch-ups or maintaining a white smile between dental visits. The Only Downside – Price: The only reason I’m giving 4 stars instead of 5 is the cost. They work well, but they are more expensive than many over-the-counter whitening options. That said, you are definitely paying for convenience and quality. Overall Impression: If you’re looking for an easy, no-fuss way to whiten your teeth at home, these trays are fantastic. While a bit pricey, the convenience and results make them worth it for many people.

I found this product to work and to do so without hurting my teeth. I tried a competitor's product that uses a lesser percentage of hydrogen peroxide but you use those strips for 45 minutes each. I've tried them on two separate occasions. Both times, my teeth hurt quite a lot for many hours. The Opalescence product, however, whitened my teeth using a higher percentage of HP, did so in a more convenient 20-minute time frame, and did not leave my teeth and gums hurting. Would recommend.

This is an excellent product. One suggestion. Don’t start using this product until you’ve had a thorough dental appointment with a good descaling. This will help maximize the best penetration of the Hydrogen Peroxide gel. I saw a nice improvement in the whitening of my teeth. Caution: Everyone will get different improvement results. Keep expectations reasonable. To maintain the whitening I would recommend twice daily use of Colgate Optic White Pro series with 5% hydrogen peroxide. NOTE: Most toothpastes that claim they’re whitening toothpastes, are not. Most “whitening“ toothpastes only contain sodium fluoride which protects the enamel. Hydrogen peroxide is a whitening/bleaching agent. Colgate Optic White Pro series contains both.

If you were thinking about teeth whitening, this is for you! Extremely easy to use. Very comfortable, I wore them for over an hour with no discomfort to my teeth or gums. I noticed that my teeth were brighter after the first use! The flavor is not overpowering or strong. My dental hygienist recommended this, and it is worth the price!

These are easy to use which is great, but they did not whiten as much as I was hoping they would.

Absolutely love these whitening trays. I just wish they were around the 25 dollar mark . They are easy to use, and work really well especially for sensitive gums and teeth, I love that it came with the sensitive gel toothpaste. The only reason I’m giving it a 4/5 is because they are expensive for the number of them you get.
