You can expect to pay upwards of $500 to get mouth guards made through your average dental office, but new technologies allow you to get similar products for less. When you suffer from bruxism (clenching and grinding), it could lead to symptoms of temporomandibular joint (TMJ) disorder, including tenderness or pain in the jaw, popping or clicking when you chew, a locking jaw, earaches, headaches, and more.

‘Custom TMJ mouth guards can help, but you have to choose the right products for your needs. High-end, custom brands like OTIS, Pro Teeth Guard, Sentinel, enCore, JS Dental Lab, DenTek, Brux, and SOVA are all great. With a little comparison shopping, you’ll have no trouble finding the perfect product for your specific needs.

Will a Mouth Guard Help TMJ?

There are several potential causes of TMJ disorders, but bruxism is among the most common, and many patients see improvement with a custom mouth guard.

How Does a TMJ Mouth Guard Work?

A custom TMJ mouth guard will conform to your teeth and bite, helping to cushion teeth and reposition the jaw to prevent harmful clenching and grinding.

How Can a Mouth Guard Help?

Reducing tension helps to ease the symptoms of TMJ so you can get a full night of rest, reduce pain, and regain function.

How Long Does it Take for a Mouth Guard to Work for TMJ?

Relief of symptoms will depend on the severity and causes of your TMJ. A mouth guard can stop clenching and grinding when you wear it, helping to temporarily alleviate symptoms caused by bruxism.

How to Clean a TMJ Mouth Guard

Like other oral appliances, your TMJ mouth guard is best cleaned by soaking it for up to 30 minutes a day in suitable, non-alcohol-based cleaners specifically designed for the purpose. These sanitizing solutions eliminate harmful bacteria that could lead to tooth decay and gum disease. After soaking, you can brush your mouth guard with a toothbrush (no toothpaste) to remove any residue, allow it to dry, and then store it in a protective case.

When do I replace my mouth guard?

With proper care, your custom mouth guard could last between five and ten years. You’ll want to replace it when you notice cracks, tears, fraying, or misshapen appearance due to wear and tear. Daily wear and rough treatment can reduce the usable life of your mouthguard. If your teeth move, you lose teeth, or your mouth guard no longer covers teeth, it’s time to replace.

Can a mouth guard cause cavities, tooth decay, or gum disease?

A mouth guard can harbor bacteria, but with proper oral hygiene and regular cleaning of oral appliances, it shouldn’t increase risk factors. Often, mouth guards reduce risks of tooth decay and gum disease by protecting teeth from harm.

Can a mouth guard damage teeth?

Custom mouth guards are designed to create added cushion between teeth, helping to prevent damage, especially for patients with bruxism. An ill-fitting mouth guard could potentially cause pain or damage due to slipping, which is why a custom fit is essential.

Can a mouth guard move teeth?

Custom mouth guards are fitted to your teeth, so if anything, these oral devices are more likely to prevent movement.

Can a mouth guard straighten teeth?

No, you will need orthodontic appliances designed for this purpose.

Can a mouth guard cause dry mouth, sore throat, or bad breath?

Because mouth guards add extra cushion between teeth during sleep, they can lead to open-mouth breathing, potentially causing dry mouth, sore throat, or bad breath symptoms. A mouth wash like Biotene that treats dry mouth can help.

Are mouth guards comfortable?

It may take time to get used to a mouth guard, but a custom-fitted appliance should be easy to adjust to and provide maximum comfort during wear.

    i have TMJ so what guard do I get? A soft one or a hard one? i can just use a top one i think


    1. The Teeth Blog Team

      Hello, Jan!

      Which mouth guard you choose (soft or hard) will depend on different factors: Do you only clench your teeth or have mild bruxism? Then you can choose a soft one. But if you grind your teeth (severe bruxism), you should choose a hard one. We recommend, before making the decision, consult your dentist.
      Hope this helps
