Many people struggle with tooth discoloration due to age, diet, or lifestyle habits. The problem is, with so many teeth whitening options on the market, it can be hard to know which one will actually work for you and give you the bright, white smile you deserve.

We understand that the process of finding the best teeth whitening solution can be overwhelming and confusing.

    I’m no stranger to teeth whitening products. I’ve whitened my teeth with the strips, at the mall kiosks and with the LED light that I got suckered into on Instagram. There’s a big difference between this teeth whitening system and the ones I mentioned above. I did a lot of research so I’ll share my experience to save you all some time.

    The whitening trays are reusable and there is plenty of gel to last for many months so you can whiten as your teeth get yellow again. Which they will. I love to keep my teeth nice and bright but they do get dull if I don’t keep it up, so it’s nice to have the trays and gel ready to go anytime I need a boost!

    You do have to be mindful when taking your teeth impressions because the trays need to cover all of the teeth in order to whiten the entire area. I had to redo my upper teeth impression the first time but the kit does contain an extra putty pack to try again and I believe they will send you a free redo kit in addition to that if you need it.

    I sent my impressions off on a Thursday and received my order at the end of the following week. Pretty fast for custom work! The gel works quickly and I’m very impressed with the results. I wouldn’t hesitate to recommend this product and company. Happy customer!!

    Whitening trays fit well and is comfortable. My teeth are definitely WHITE! Great customer service. Would reorder again.

    Once upon a time I paid $400 for this same set at my dental office. I’m amazed at the dental office markup. Thank you for offering high quality products at an affordable price. By the way, to anyone considering this, it’s by far the best teeth whitening gel in existence. Great for sensitive teeth like mine and it gets my teeth so white. I also love that I can whiten anytime I need (months apart) because it’s not a one and done system. A++

    I’ve known for years that Zoom whitening gel is the best on the market. I was surprised to find it here for wayyy less than the dental office. Well worth the investment. The results are quick and stunning. Thanks for making this affordable to the general public!

  • Betsy R.

    My teeth weren’t too bad but some yellowing from coffee stains. I’m a former dental assistant and know that getting the gel on your gums can be irritating so be careful. The instructions say to have it on for 2-4 hours. I kept it on for about 45 minutes each session and it takes about 5 days to see optimal results. Only 1/2 of the one tube out of 3 were used so plenty of gel leftover for future whitening. Highly recommend!!

    New customer here! Lovely website, fantastic & friendly staff. My experience is that this small company offers a great teeth whitening solution at a price that was way lower than my dental office. I was dreading taking my own teeth impressions but this was a great, pain free experience! My teeth are so much whiter than they were and I didn’t get any tooth sensitivity. Happy camper!

  • Heather Z.

    All the other bleaching trays I’ve tried have made my teeth hurt terribly. I love that the gel is for sensitive teeth. I reached my optimal color on day 5 with no sensitivity. I have plenty of gel leftover to re-whiten when my teeth start to color again. Happy with the service and product *****

  • Khloe M.

    I know first hand that this is a good deal because my dentist office has this exact same at-home teeth whitening system and it is being sold for $500!
    I looked online to see if I might get lucky and there it was.
    This gel is a very good teeth whitening gel and I love that you can reuse it unlike the whitening strips.
    Excellent product, fast delivery, and free shipping. Can’t beat it!

    I don’t write reviews very often but my hunt for a teeth whitening product that doesn’t make my teeth feel like all the nerve endings are firing at the same time has ended! I don’t leave the gel on very long because I have super sensitive teeth but it still has whitened my teeth very well. I still have plenty of gel left over to re-whiten when they start to yellow again too. The professional quality trays fit snug on my teeth. I’m very pleased with the whole experience.
