How Does Sporting Smiles Work?

With Sporting Smiles, you can create your customized night guards from the comfort of your couch. Sound too good to be true? We’ll walk you through the process from beginning to end.

Creating Teeth Impressions At Home

While it may seem daunting to create your own teeth impressions at home, Sporting Smiles makes the process easy. In your impression kit, you’ll find one adjustable impression tray and some dental putty.

Before creating your impression, thoroughly brush your teeth and wash your hands. Then, check the size of your adjustable tray. You can easily push in the sides to adjust its width. If its too long, simply tear off the perforated section at the end.

Once you’re certain the tray fits correctly, thoroughly combine the white and blue dental putty and roll it into a long tube. Quickly place the putty into the adjustable tray and place into your mouth. Bite down into the putty and let it harden for four minutes.

After the putty has completely hardened, gently remove the tray from your mouth. If you aren’t sure whether the impressions worked well, you can email a photo of the putty to [email protected]. A representative will quickly respond and offer assistance.

Sporting Smiles Impression Kit

Accidentally mess up the impression? Not to worry. Sporting Smiles will mail you some replacement putty and help you troubleshoot the issue.

In our experience, creating impressions at home is simple and easy. Sporting Smiles mails each customer a thorough pamphlet explaining how to get the best teeth impressions possible. I even emailed a photo of my hardened putty to a representative and received confirmation within the same day.

It’s never comfortable getting teeth impressions done, so you may want to mentally prepare for it. In our experience, it was helpful to relax on a comfy pillow and listen to soothing music during the process.

Shipping The Teeth Impressions

After the putty has completely dried, ship your impressions to Sporting Smiles using their pre-paid return label. Once Sporting Smiles has received your impressions, the completed night guard should arrive on your doorstep within 10-15 business days.

Need additional products? Sporting Smiles keeps your impressions for a year, so you can easily order whitening trays, retainers, and sports mouth guards. Plus, all of Sporting Smiles’ high-quality products come with a 30-day perfect-fit warranty. If you aren’t happy with your product during this period, Sporting Smiles will remake your order or issue a full refund.

Types Of Sporting Smiles Night Guards

As you peruse their website, you’ll notice Sporting Smiles sells a wide variety of night guards. We’ve outlined the differences between the models below to help you decide which one is right for you.

Soft Grinding Guard

This soft night guard was designed for people who significantly clench their teeth and lightly grind them. Made with 3mm of EVA material, the Soft Grinding Guard feels especially soft and flexible. This night guard is available for both your top and bottom teeth.

Hard Grinding Guard

This super thin, custom-made night guard works well for people who moderately clench and grind their teeth. Unlike the soft grinding guard, this model only covers half of your tooth height. It’s also thinner, using only 1mm of EVA material.

Dual Laminate Guard

The Dual Laminate guard has a soft inner layer and a hard outer layer, so it should feel comfortable and offer the protection you need. It’s 3mm thick, and it should have a long lifespan.

The Dual Laminate Guard is available for both upper and lower teeth. For an additional $5, you can purchase the backcut version. This model is shaped slightly differently, and it’s meant to feel more comfortable and look less noticeable.

Flexible Super Hard Guard

If you really grind your teeth at night, opt for the flexible super hard night guard. This is the model we tried out, and it happens to be Sporting Smiles’ most popular option.

Made with 3mm of EVA material, this mouthguard feels both flexible and durable. It works best for people who often clench and grind their teeth at night. Like the Dual Laminate guard, this model comes in a backcut version.

Sporting Smiles Hard Flex

The Flexible Super Hard Night Guard is super convenient and provides excellent coverage. In our experience, this mouth guard feels especially comfortable. It fits snugly against your teeth, and it protects against grinding much better than your average over-the-counter mouth guard.

However, if you grind your teeth especially hard at night, you might need to replace your night guard often. Sporting Smiles’ products are not as thick as some of the night guards you’ll get from dentist offices, so it’s important to assess your needs before purchasing this online night guard.

Avoid Caffeine In The Evening

Caffeine can trigger stress and anxiety, especially if consumed before bedtime. If you’re prone to grinding your teeth, this stimulating substance could make the problem even worse. For the best results, cut off your caffeine intake at least five hours before going to bed.
