Woman waking up happy with a night guard

The best custom night guards for teeth grinding

We all have our different stories. Maybe you've dealt with teeth grinding your entire life but haven't found the solution to it yet. Perhaps you've recently started grinding your teeth due to stress in your life. Maybe you've woken up with intense jaw pain or consistent morning headaches and you've done your research and discovered that you likely grind your teeth at night. Whatever the case, you've come to the right place for your solution. With over a decade of crafting custom night guards for teeth grinding, Sporting Smiles offers a variety of both day and night teeth grinding guards to prevent further damage and to restore the peaceful nights and mornings that you seek. Stopping teeth grinding starts here!

This unique hard flexible dental night teeth guard is constructed using a new advanced material that is flexible, but extremely dense. The flexibility of this teeth grinding mouth guard makes it work well for teeth clenching and the density can hold up to the most severe teeth grinding. This is the only night guard that our consulting dentist prescribes in his practice. The hard flexible night guard can be created for either the upper or lower teeth but will provide the same level of protection.

100% Satisfaction Guaranteed.

This is the same product you would get from a dentist\orthodontics without the cost and the need for a dental visit.

Frequently Asked Questions:

Is it hard to make the impressions at home? - We’ve helped thousands of people successfully make their at-home impressions using our kit. Because everyone’s mouth is different, it’s important to have an impression tray that adjusts. In 2011, we patented our adjustable tray to make it even easier to get a perfect impression. We include an extra set of impression material, just in case. You’ll want to watch the video and make sure you’ve got everything prepared properly. But in our experience, making the impression at home is much easier than scheduling an appointment, driving across town, sitting in a waiting room, and spending hundreds of extra dollars to have your orthodontist do this for you.

How Long Does It Take to get my custom teeth grinding guard? - As soon as your impression is received, it will take approximately 10 business days before your new appliance is completed and shipped. International shipping can be a lengthy process. Please be patient when ordering internationally. (We ship same day orders Monday through Friday with orders placed before 3 PM CST) During holiday sales, we experience a massive influx of orders. While we will do our best to complete your order as quickly as possible, processing times are subject to change with orders from holiday sales. Please be patient with our team during these times. 

What if I mess up my impression? If the impression material hardens or the impression doesn't come out well, we will send you out a replacement putty free of charge, the tray is reusable. If the kit is sent in and the impression(s) were bad it would be a 15 dollar charge to cover shipping you another impression kit.

Are there other names for teeth-grinding guards? Yes! It might depend on where you live or how old your dentist is but the terminology that revolves around teeth grinding guards can be confusing so we'll make it easy for you. Teeth Grinding Guards, Night Time Guards, Day Time Guards, Bite Guards, Occlusal Splint, Bit Splint, Sleep Guard, Bruxism Guards are all the same thing! They are just different terms used for guards to prevent teeth grinding.

What are the symptoms of teeth grinding? You may be grinding your teeth or clenching your jaw at night without even knowing it. Symptoms of teeth grinding include:

1. Waking up with jaw pain 

2. A noticeable shift in your teeth

3. You suffer from stress, anxiety, or depression

4. Your teeth are sore or hurt 

5. You've recently had teeth removed

If you sleep with a partner, they may be able to spot other symptoms of teeth-grinding including hearing you snore often, hearing a grinding or clicking noise coming from your mouth at night, and witnessing you tossing and turning in bed. 

Are your products BPA Free? - Yes! All our products (retainers, whitening trays, night mouth guards, and athletic mouthguards) are BPA, BPS, DEHP, and latex-free.

Does Sporting Smiles accept HSA or Flex payment options? Yes! You can use your HSA card and if any special invoicing is required Sporting Smiles will work with your insurance company to complete the transaction. Teeth-grinding guards are an excellent choice to spend your HSA account on. Teeth-grinding is a serious oral health issue and without proper care or a solution can lead to expensive surgery or permanent facial reconstruction as the jaw bone shifts. 

Can I add whitening trays to my night guard order?

Yes, but UPPER AND LOWER IMPRESSIONS ARE REQUIRED!

You will receive enough supplies to make an impression of your upper and lower teeth even though you ONLY ordered 1 upper or 1 lower for your Night Guard as you WHITEN your upper and lower teeth. 

Whitening Trays are made with different materials than the night guard. Whitening Bleach can not be used on night guards, only custom whitening trays.

Why is Sporting Smiles so much cheaper than my dentist? - To purchase a typical retainer in the past, your dentist would have to take an impression at his office and send it out to a dental laboratory for construction. This requires using valuable office time which needs to be incorporated into the cost of the guard. Because we operate our laboratory and are using a self-impression method we can dramatically reduce the cost of your retainer.

I Have a Small Mouth, Do You Have Smaller Impression Trays? - Our patented impression trays fit over 95% of our customers because they are adjustable and are designed to fit any mouth, large or small. In some rare cases, if you know you have a small mouth we do offer smaller trays. If you are in this percentile for small mouths, please contact our customer service before ordering so we can put a note on your order to send small trays.
