About J&S Dental Lab

The company has created 5 different guards and a set of accessories to help you feel better. These can meet varying demands from bruxism, TMJ-related pain, clenching, or teeth grinding.


The company uses its own professionally trained and skilled lab technicians in a highly specialized setting. Dental guards that you order are created with the same techniques and materials as the guards J&S creates for dental offices. Each guard is a custom creation and will be made specifically for your mouth.

J&S promises that it uses only FDA-approved and safe materials. The company also guarantees that your guard will fit comfortably.


Product Features

J&S has created 5 different products to help ease bruxism and the pain of teeth grinding. Read the following descriptions as well as our pros and cons sections to you can pick the right J&S option today.


0.12″ Soft Custom Night Guard For Light Grinding

Like its name says, this guard is designed for the lightest of grinding and is made with two layered sheets of material laminated into a single guard. This gives it more abrasion resistance. The guard will last between 6 months and 2 years based on your level of bruxism.



0.12″ Durable Custom Night Guard For Minor Grinding

This mouth guard provides you slightly more protection and uses the same laminate process but has a harder material to give you slightly more protection than the prior model or most athletic guards. The lifespan of this guard typically ranges from 1 to 3 years.






0.12″ Hard Custom Night Guard For Moderate Grinding

For this guard, J&S uses a dual-laminate process combining two strong materials into one with a vacuum sheet formation technique. This means your guard will be hard on the outside but soft and gentle for your teeth and gums on the inside. The outer surface is tough and gives you a longer wear while it stays comfortable as you sleep. The lifespan of this guard typically ranges from 1 to 3 years.



0.08″ Extra Durable Custom Night Guard For Severe Teeth Grinding/Bruxism

If you suffer a very extreme case of bruxism, this guard will still help prevent you doing damage to your teeth. It’s a tough acrylic material specifically developed for bruxism treatment and is still latex and BPA free. The material is also used by many dentists. This guard can last up to 5 years for users, with the minimum amount expected to be around 2 years.



0.04″ Custom Day Guard For Day Grinding

This day guard uses the same dual-laminate processes but both are made of hard acrylic to give you a very strong protection. It is designed for moderate to heavy grinding. For those with severe cases, it will last around 6 months. Some users have had it for up to 2 years, however. This is the only guard designed for specific day use and will allow you to speak easily with it in your mouth.


Quick Product Comparison

On its website, the company offers combos with day and night versions of these guards or additional packaging options, some of which give you a slight discount on your order or for repeat orders.


Your Impression Kit

Each impression kit will include the same basic set of materials to help you create your custom mouth guard.

  1. Prepaid return postage box
  2. 1 set of putty in 2 containers
  3. 3 different sizes of mouth trays for better fit: Adult male, adult female, child
  4. Detailed instruction for creating the guard.


Creating Impressions

You can create the mold for your guard in just one to two minutes according to J&S. The company will ship you instructions and provides this video to help you with your mold creation.

The steps are common for the industry and include:

  1. Take the putty out of both containers.
  2. Roll them together and thoroughly mix. Create a hotdog shape with the mixed putty.
  3. Place the putty into the outer edge of the tray and press it into the tray firmly.
  4. Put the whole tray in your mouth. Press it into your back teeth as well.
  5. Hold it for 5 minutes.
  6. Pull down lightly on the tray to let air in. Remove the tray by gently pulling down.

 Now you’re ready to ship it back to J&S in the prepaid box.




Is it different from the mouth guard I’d get at the dentist?

Since J&S uses dental technicians, you’ll be getting the same quality guard as most dentist customers just without the added costs needed to pay dental office staff.


How do you clean it?

It’s best to clean your guard each day by brushing it with toothpaste and rinsing it with warm water. You can also wash it with mild hand soap or soak it in mouthwash for 15 to 30 seconds.


What materials do you use?

Depending on your guard, it will either be made from a hard plastic called acrylic, a custom dual-laminate material, or a prefabricated dual-laminate material called ProFlav. All of these materials are approved for use in the dental industry and used by many other dental labs and offices.


What about processing and shipping?

Impression kits are shipped out within 2 business days and customers usually get them in between 3 and 6 days. Once you send back your impression, it will take roughly 5 to 8 business days for the device to be created and mailed back to you. The howl process takes between 2 and 3 weeks.


What’s the return and refund policy?

The company requests that you contact them directly for the refund and return options based on your mouth guard. Typically, they ask you some questions over the phone and then have you return the guard via the mail. Once they receive it, you will be notified and your refund will be processed. It can take between 3 and 5 days for the refund process to go through.


What if I’m not happy?
