  • 35% tooth whitening gel

    I've used this product for about three weeks now, 2-3 times per week. I am very pleased with it's whitening properties - much better than the 7% gel I received from my dentist. I have custom fit trays that my dentist made for me, and so far have not experienced any gum or tooth sensitivity. I've only been leaving the gel on for 15-20 minutes at a time, and taking a couple of days between applications.The instructions that accompany the product are very basic, but it seems with some common sense most anyone would be able to figure it out. Overstock's delivery of the product was, as usual, very quick. I paid over $60.00 for whitening gel from my dentist, which was only a 7% strength and came in four TINY tubes, so this is definitely good value for the money.

  • Whitener

    I had purchased a whitening kit previously and could not find my gel refill. This was something I researched to make sure I could find a gel that would work in a timely manner like my previous gel. This gel did exactly that. Within 3 days I could significantly tell a difference in shading. My teeth were not severe. However, the daily coffee and other foods do take their toll on the whiteness level. This took the dullness and the staining of all of that away. I used one tube within a week, using the product nightly. Then I took one week off to cut down on any sensitivity. I did this as a precaution, because I did not experience any irritation. I'm a skeptic so it meant something to me for this to work well enough to write about it. It does a great job, expecially for the price. It is worth it.


    I would recommend this product to everyone. I paid my dentist 150.00 for the same product. I saw results in one day. I ordered for myself, everyone at work started asking me about my teeth, so I ordered two more for people at work. You can keep it in the fridg. for up to 3yrs. So I will be about to do touch up whenever I like.

  • Great!

    Having retired from being a dental assistant, I knew what to look for in this product. And it was all positive! It did not come with trays, which can be expensive if you don't already have a set (I did). But I found the process of filling the trays easy. All that is needed is a steady and controlled hand. When placing the tray into the mouth, I found using a Q-tip to remove the excess along the gum line worked fine. The solution is very strong so it is important to remove any extra or you will devintely have burning gums. I saw an immediate imporvement after 2 sessions of 1/2 hour each. I don't remember the directions saying anything about not eating or drinking anything for a while after using solution, but it's a good idea not to. Particularly coffee, tea or red wine. This product is definitely worth the money and it gives the results you're looking for.

  • Strong product

    Have not used yet, but good value for price. Plan on using in next few weeks.

  • Works great!

    I like that I can use this for a short amount of time and see good results. It's strong so I just don't overfill my trays in order to lessen the irritation, which I personally tend to get, when whitener gets on my gums. I have had no problems with this and can definitely see a difference after each use. Worth the price and wish I had been using this all along instead of the more expensive, yet less potent, whitener from my dentist.

  • Teeth whitening gel review

    I can't use the product if that happens to touch my gums at all it burns inside my mouth so bad I can't keep my whitening trays in my mouth too intense and Use a lot of different teeth whiteners but this is ridiculous . I should have realized something was up with this product when there was a big warnings disclaimer on how to protect to protect your gums well it's kind of impossible sometimes.

  • Great product

    I took a chance and purchased this.Brightened my teeth immediately. Not for sensitive gums. Irritated my gums the first time but after that no problems. I hope it will be around when I run out! Quite a bit of whitener for the price. I am very happy with it.

Thank you for contacting us brody123. If you haven't whitened before I'd start with about an hour, and a few days between sessions. Please let us know if you have any further questions. overstockcustomercare1 on Sep 30, 2013

No!! m2thap on Jun 11, 2013
Mine did NOT come with instructions, but there's not much to it. If you haven't whitened before I'd start with about an hour, and a few days between sessions. After you know what to expect it's easy to keep in longer or use more often, totally up to you. mountainlora on Jul 27, 2013
I did not get instructions, but this product is for people who already have had teeth whitening products and have their own trays, thus know how to use it. marynassar64 on Oct 3, 2013
