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”.

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!

    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.
