FAQs
I'm getting new crowns soon. Should i wait to purchase a custom guard?

We highly recommend that you wait! After having new crowns put on, your teeth need time to “settle”—and then your dentist can make any additional adjustments before you fit yourself for a custom night guard.

Do your night guards work with dentures?

Yes, you can wear our custom guards to protect dentures, implants, and natural teeth from grinding and clenching while you sleep.

Do you accept insurance?

Currently, J&S Dental Lab does not work directly with any insurance companies. However, our night guards can help improve your overall health, reducing issues that may lead to mounting dental bills down the line and impede uninterrupted sleep. So, they are great investments!

Can i use your products with my retainer?

Of course! Our custom guards work with both removable and bonded/permanent retainers. Simply send an image of your retainer to support@jsdentallab.com and provide your order number, so we can ensure the proper fit. We also recommend consulting your dentist initially to see if wearing a night guard is right for you.

Do your night guards help treat sleep apnea?

Our guards are not meant to treat sleep apnea. We design them to protect your teeth from the effects of nighttime grinding and clenching (bruxism).

Do you have a return/exchange/refund policy?

Absolutely. We offer free adjustments for a full year after your purchase. If adjustments don’t work, you can return your guard for a complete refund or exchange it for a different night guard.

What materials do you use to make your night guards?

We make all of our night guards with premium dental use materials from the U.S. and Germany. They are latex, BPA, and Phthalate free.

Should i get a night guard for the upper or lower part of my mouth?

It’s up to you! For the best experience and results, choose a top or bottom guard based on which part of your mouth has the best teeth alignment. Ideally, you want to choose an area with no missing teeth and well-aligned.  And if you have a loose tooth, have it stabilized first before wearing a night guard to protect it from being further traumatized from grinding and clenching.

Do your night guards last longer than over-the-counter guards?

Yes! You can expect your custom guard to last between one to five years—sometimes even longer. Durability depends on how severe your grinding and/or clenching is, and how well you maintain your guard.

If your guard stops working sooner than expected, we’ll give you a partial refund, a friendly discount on a new guard, or a completely free replacement!

Will you send a new impression kit if mine doesn't work the first time?

Certainly. If your impression doesn’t come out right—or if the three tray sizes don’t fit your bite—just let us know and we’ll send another kit free of charge (with smaller or larger trays, if necessary). We also have tray sizes for children!

I have an existing teeth mold from a non- J&S impression kit. Can you use that to create my custom guard?

Sure! Even better—your existing mold makes you eligible for our repurchase discount, as long as the mold is still accurate and in usable condition.

Are 3D guards different from your standard night guards?

Yes, 3D guards use more comprehensive data collection to combat teeth occlusion—including overbites, underbites, crossbites, and other alignment issues.

How soon will i have my custom guard?

Very soon! Typically, you’ll receive your custom night or day guard within 7 to 10 days of mailing us your finished teeth impression.

Can i use your guard as a teeth bleaching tray?

Yes, but we don’t recommend it. For the best teeth bleaching results, use a custom-made bleaching tray. Our night guards feature a different design than trays made specifically for bleaching.
