GLO ScienceBrilliant 3 Pack Teeth Whitening Gel Treatment Kit for Fast, Safe & Effective Teeth Whitening Without Sensitivity, Pain – Free, Long Lasting Results. Clinically Proven.

This is the product my dentist recommended for the teeth whitening system I purchased. Purchasing it through Amazon is cheaper than buying it from the dentist.:)

I found this product very messy to use. It didn't seem to enhance the whiteness of my teeth.

This product is an improvement to other whiteners I've used. The gel is a bit thicker than most gel whiteners, making it easier to apply to specific areas. A small issue with the cap: Would be advisable to direct customers to pull lid straight off, without turning the lid. I inadvertently turned the cap & this caused the top brush area to break. Do not hesitate to try this gel - it does work - it's the real deal.

I have the mouthpiece that lights up from this brand so I love these for when I need refills. Amazing price. They are cheaper here than in “beauty” stores. One thing though, make sure you take the tube apart when you think it’s empty. There is a lot more product you can get out. I have very VERY sensitive teeth and all other whitening products cause pain and sensitivity to even air, but I’ve never felt any pain or sensitivity with these. As long as they make these, I will buy them. 10 vials will last you a long time. When I use these I can usually get several shades whiter after about 5-6 days.

I'm so glad that the GLO Science teeth whitening device has refills so I can maintain my newly brightened smile! 5 treatments was enough to do the trick and get my teeth noticeably whiter, but I know that inevitably they'll lose their luster (probably due to my coffee habit). These refills are perfect for following up and maintaining the work I've already put it. They're convenient refills, shipping is quick, and I have them on hand for when I need them. I also want my husband to try the GLO device since his teeth tend to get stained easily, and of course GLO is washable and reusable. I bought this refill pack more for his benefit than mine, I just keep forgetting to remind him to use it (lol our memories make quite the pair). Looking forward to seeing his results now that I've seen how well it worked on my teeth. The teeth whitening gel doesn't taste as bad as a lot of the teeth strips I've tried, and it sticks to my teeth well. It really helps make the overall process as simple and user-friendly as possible. I'd highly recommend this, I just wish it had a subscribe and save option, because I will probably want to get a refill pack every 4-6 months for either myself or my husband.
