Product Description

Flag Design Custom Mouth Guard

You choose you flag! Represent where you’re from

This custom mouth guard is made with two thin layers of dentist approved durable material using top of the line mouth guard machines that combine the latest high heat & pressure technology. We understand the needs of an athlete. This thin design allows you to breath and communicate so you can concentrate on what matters. Recommended for medium to high contact sports. Here’s how it works: We mail out a dental impression kit to you (mixing putty & a plastic tray). You take your own dental impression following our easy instructions. Using the pre-paid mailer, send us your impression. Upon receipt of the impression we will fabricate your new custom-fit, custom-designed mouthguard within 5 business days. That’s it!

*Please note your mouth guard is custom made for you based on a dental impression of your teeth. As dental anatomy varies from person to person, final product may not appear exactly as seen in picture.

  • Leading Mouthguard Technology
  • Absorbs The Most Destructive Force
  • Thin Design For Ultimate Comfort
  • Guaranteed Customer Satisfaction

    Worth the wait of having a custom mouth guard made. I have a really huge mouth so I’ve always struggled finding a good fitting mouth piece. These guys have exceeded my expectations. My days of $10 mouth guards are over. I’ve spent so much money biting through & replacing the cheap ones I could’ve bought several of these by now!

    Scoured the internet for a Canadian flag design that wasn’t super cheesy. Was stoked to find this store. By far the best designs. Plus it’s not bulky like my others. It’s thin and lower profile than other types I’ve gotten (even custom ones I’ve had made in the past). A+++ You have a customer for life 😀

      Hi Ryan!

      Happy to help– As we have not added a variation to choose a specific flag, simply checkout as normal and type in the comments box that you would like the russian mouth guard.

      Let me know if I can be of any further assistance:)
