Opalescence GO 15 Teeth Whitening Trays Bundle 15% Hydrogen Peroxide 5194-T | Gel Prefilled Trays - Includes 2Chill Toothbrush Made by Ultradent Products USA. Teeth Whitening Kit -Mint - (10 Treatments)

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

Love... whitens my teeth, easy to use and reasonable price.

Stuck between a 3-4 because this works really quickly. My teeth are AT LEAST a shade or two whiter. I used them a few times, no problem. The following use a few weeks later, it really hurt my gums. I don’t recall getting any gel off the teeth strips, but they were extremely sore in some places following taking them off. I still will use them because they work so well, but I will try to find a barrier (or something) to put by my gums next time. Just like what my dentist gave my when I got the trays and syringes you keep in the fridge. That powerful!

My dental hygienist recommended this brand for teeth whiting. Made for sensitive teeth and so much better than the strips found in the grocery store. Comes w 7or 10 trays with teeth-whiting gel already in them. Highly recommend

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

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.

**Whitening Material Never Releases from the Tray**⭐⭐☆☆☆ **2 out of 5 stars**I really wanted to like this product because of all the positive reviews, but it simply didn't work for me.The biggest problem is that the whitening material never releases from the tray. I place the tray over my upper or lower teeth, bite down firmly, and even press against it with my fingers to make sure it's fully seated. When I remove the tray, the entire whitening material is still attached inside the tray instead of transferring to my teeth. As I try to remove it, it folds over on itself, sticks together, and is no longer usable.I also found the trays uncomfortable because they triggered my gag reflex.After using the product consistently for two weeks, I saw no noticeable whitening. I've had much better results with Crest Whitestrips, which are much easier to use and actually stay on my teeth.Unfortunately, this product was a complete disappointment for me, and I won't be purchasing it again.
