The tray that's included in this kit is terrible. I threw it out. It doesn't fit your teeth well so the gel really touch come into contact with the surfaces of your teeth rendering this tray thing useless. Instead, buy the gel and rinse and then buy one of those sport mouth guards that mold to your teeth with warm water. Follow the directions to form the mouth guard to your teeth and you'll have yourself a solid teeth whitening solution for a FRACTION of what a dentist will charge you.

Long story short - I use it 2-4x / week 15 minutes each time. Going on three weeks. Seeing results.I’ve used all kinds of whitening tooth pastes, charcoal, power tooth brush, crest strips and even professional dentist kits ($$$$)... a friend at work with porcelain white teeth said she uses this 2-3x a week for 10-15 min (like when she takes a shower) and I started using it and I’m on week 3 and notice a difference! I joke that my teeth are “like shale”... every time I visit the dentist there’s something I have to fix (cavity, chip, gums... I brush 2x a day and floss just got bad teeth, and only 30 years old) any ways, no noticeable sensitivity after 3 weeks of 3-4x / week 10-15min each time. Cheap, easy to use, noticeable difference, no side effects.Charcoal tooth pasted left dark spots around my fillings (I have two front teeth fillings), whitening toothpastes didn’t give me clean enough mouth feel, and strips left me with sensitivity... and dentist kits were $$$$ an I can’t say they were better than this stuff, if you have the patience!

It does take a while to start noticing a big difference but what do you expect when you let your teeth go for a long time. After a week there were noticeable difference and then after 2 weeks. White Read more

The tray is awful. It's like jelly so it's not moldable. When you bite down, it doesn't even touch the front of your teeth to do the job. I'm waiting for my new sports tray to come in that you mold to your teeth for better results, but I'm already 4 days in and am noticing a difference trying to make it work in the meantime. To avoid the issues where the tray lacks, use a q-tip and rub the gel on each individual tooth, then put some in the tray, and bite down for the allotted time. Read more

Can you tell which is the before and after?! Yeah, neither can I. I have been leaving this stuff on for 10 minutes at a time and it has done absolutely nothing!! I’ll be getting my money back on this! Read more

Better than most everything on the market , for a fraction of the price, Use it in unison with my “my smile light tray”and it worked immediately and visibly whiter after only one use, compared to the “my smile whitening solution ” which I have used for weeks about 3 times a week ...and saw barely any results ....

Follow the directions, and the results are undeniable. I thought my mother had her teeth whitened professionally, that’s what led me to the purchase. Read more

Use for five days in a row every 4 months for the whitest teeth. Great value! Read more

The tray it comes with is terrible, does not fit on my teeth. The tray is very lose and does not do much. I used my own mouth guard with the solution. The whitening product isn't bad, don't expect a dental office white but it does work. Only made my teeth about 1-2 shades whiter, the solution isn't strong enough even after leaving on for 20+ minutes at a time over 2 weeks. Read more

I've bought this product from stores for years and thought it worked great. I'd receive nice compliments about my smile. Something has changed in the formulation because my last two purchases of this product have not been gel-like but instead very runny. This defeats the product because now it won't stay in the tooth tray but just runs right out and into the sink. 90% of the purchase ends up wasted. Read more

Even within 2 applications, I've had noticeable whitening and minimal sensitivity that only lasted a couple hours. Product is a little messy, don't squeeze too much out.Also the seller was great for customer service. Read more
