Best Bang For Your Buck

Not only does the powerful ZOOM! whitening gel give stellar first time results, the Sentinel upper & lower custom made reusable teeth whitening trays are the solution you’ve been looking for to keep your teeth consistently white.

When we compare custom fit trays that are made specifically for you to other forms of teeth whitening (white strips, white lightening, mall kiosks, etc) one can quickly see the short term and long term advantages of using the custom fit trays.

Comfortable Custom Fit

You cannot get a more comfortable fit than thin clear trays that are made specific to your exact dental anatomy. Many wear these trays while they’re at work interacting with clients & co-workers because they’re so unobtrusive & unnoticeable.

Reusable Trays

Unlike most teeth whitening methods that are only good for one treatment, your custom trays can be used and reused for years. When you run out of gel, simply order more! Your teeth will stay white year after year. The Sentinel Teeth Whitening System truly does give you the biggest “bang for your buck”.

Manufactured by Discus Dental, the maker of the venerated ZOOM! one-hour tooth whitening system.

Taking your own dental impression is EASY

What you get in your kit:

  • upper and lower plastic trays + plenty of dental impression putty
  • written instructions
  • prepaid envelope to mail impressions back to us.

You need to have a timer, clean hands, & good solid teeth. No braces. Seriously, putty & braces do not mix.

We will give you a link to a video, pictures & written instructions to show how to take your teeth impressions and make sure you get a perfect mold of your teeth.

Here’s how it works:

We mail out an impression kit to you (mixing putty & a tray). You take your own impression & using the prepaid envelope, mail it back to us. Upon receipt of your impression, we will fabricate your new custom fit teeth whitening kit within 3-5 business days. That’s it! You’re on your way to a brighter smile!

Product Reviews

  • Gloria Robbins

    I’ve been using this same pack of gel I got 9 months ago and I still have 2 syringes left! I whiten periodically whenever my teeth need a boost. I love this because I used to spend so much money on Crest whitening strips. I have everything I need to keep my teeth white any time I want. This really is the best bang for my buck!

  • Vi Henderson

    Wanted these EXACT trays and whitening when I saw them advertised at my dentist for $500! I looked online and got the same product for $300 LESS! The power of the internet!
    Yes, it takes a bit of time to make the impressions and get the final delivery but worth the savings! My teeth have gone from yellow to a nice white. I do have some tetracycline stains that won’t come out but I’ll live with it. Much improved smile! Thank you!

  • Brenna Godwin

    You can’t go wrong with this!!

    This teeth whitening system is the real deal. I’ve been using other types of whitening for years and much of it is expensive junk. I whiten my teeth about every 6 months and this is perfect. The trays fit like a glove. It took about 5 days to see optimal results for me using the zoom gel nightly for a couple of hours. Plenty of gel left over for future whitening! 5 stars!!

    Same exact thing at the front counter of my dental office. Saved several hundred dollars and it works beautifully! I actually had to take two dental impressions because you have to get your teeth all the way in. But there was an extra set of putty for a retry. Nailed it the 2nd time. Beautiful fit. Thank you Sentinel team. -Julie

  • Michelle

    I got this for my mom as a Mothers Day gift to use for her high school reunion.It worked so well that I got one myself. Great buy!

  • Jeff Cohen

    I bought a dental guard from Sentinel and was so pleased with the service and fit of my sleep guard that I decided to try out the teeth whitening. I’ve always had little to no success with other whitening products so I was skeptical. I would recommend this whitening regimen to anyone. Worked absolute wonders on my coffee and tea stained teeth Happy camper!!

    Works quicker than I expected with fantastic results A++++

  • Robert F

    Easy to use teeth whitening! I pop them in and watch tv. I had whiter teeth in 2 days.

  • P. Cooper

    Thank you so much Sentinel! The peace of mind from being able to smile without holding back is worth so much more!

    Just wanted to pop in and tell your team thank you for the outstanding customer service. I had a small issue with the fit of my tray for my top teeth and you all were so professional and prompt in getting my replacement to me. Excellent work. Thank you! -Jane

  • Heather R

    This is one of the best teeth whitening products I’ve used. I’ve tried everything including one of those mall kiosk “teeth bleaching” set ups which didn’t work at all. This actually does. Love it!

  • Shelby Seattle, WA

    Wonderful results! My dentist doesn’t offer deals like this! Lucky to have found you Sentinel!
