What is TMJ?
This is a joint on either side of your jaw that acts like a hinge that connects your jawbone to your skull. TMJ disorder, often just called TMJ, causes pain in the jaw joint and in the jaw muscles.
TMJ disorder can be caused by genetics, injuries, or arthritis. In some cases, people who grind their teeth or clench their jaws may also develop TMJ disorder.
While the pain and discomfort caused by TMJ is no fun, the good news is that it's typically easy to treat with home care and only requires surgery in extreme cases.
How do you know if you have TMJ?
The only way to be sure if you suffer from TMJ disorder is by visiting the dentist. They can diagnose you, or refer you to a TMJ specialist, who can discuss causes and treatment options with you.
However, you may want to speak with your dentist about TMJ disorder if you experience the following symptoms:
- Jaw pain or tenderness
- Pain in your temporomandibular joints
- Ear aches
- Painful chewing
- Facial aches
- Jaw locking, clicking, or grating
- Limited jaw movement
Do mouthguards help TMJ?
If you have TMJ, your dentist will most likely recommend some lifestyle changes, including mouthguard wearing, eating softer foods, icing the joint to reduce inflammation, and taking pain meds. It's only in more severe cases that surgery is recommended.
Mouth guards are a treatment method that your dentist may prescribe to help ease your TMJ because a mouth guard can ease some of the most irritating TMJ symptoms.
That's because mouth guards, or night guards, can help you stop grinding your teeth or clenching your jaw when you sleep, which will ease a lot of the pain you experience. Some mouth guards are specially designed to stabilize your teeth, or even reposition your jaw by making your muscles relax, although this type should only be used if prescribed by a dentist.
Types of night guards for TMJ
There are many different types of mouthguards on the market, some of which will be more useful when it comes to treating TMJ.
Over-the-counter mouthguard for TMJ
These are mouth guards that you can buy online or at the drugstore, and they typically aren't the best solution. There are three main types of OTC night guards:
- Adjustable: These are made of a material that becomes flexible when placed in warm water. This means that you can readjust them as needed.
- Boil-and-bite: These mouth guards are boiled in hot water, and then you set them by biting down and letting them cool and form around your teeth. Once they have cooled, they are no longer moldable.
- One-size-fits-all: This is the cheapest and arguably least effective mouth guard you can buy. They can't be adjusted, so if you purchase one, you'll just have to hope that it's a good fit. If you feel pain after wearing this mouth guard, you should stop using it immediately.
Custom mouthguard for TMJ
Custom mouth guards generally work much better to ease the symptoms of TMJ and other problems like tooth grinding and bruxism because they are tailored to your specific teeth and mouth.
These can be ordered online for convenience. Typically, you first order an impression kit so you can make molds of your teeth at home.
You then send the molds back to the company, and they'll have your custom mouth guards made in a dental lab. Once they send them back to you, you can start wearing them to ease TMJ.
These companies will also keep the molds of your teeth on file so that if you need to order a replacement mouth guard you don't have to retake your tooth impressions.
One reputable company that offers custom mouth guards for TMJ is Smile Brilliant. You can choose from different packages depending on your needs.
Prescription mouth guards for TMJ
If you go to the dentist with a more severe case of TMJ, they might prescribe you a mouth guard depending on the conditions and symptoms you have. There are two main types of mouth guards from the dentist for TMJ:
- Stabilization splints: These mouth guards cover all of your teeth and are designed to prevent clenching and bruxism. They can be either soft or hard, depending on your needs, and ease TMJ pain by helping jaw muscles to stop overextending or overworking. NTI night guard is one prescription brand that may ease pain.
- Repositioning splints: These guards actually pull your lower jaw forward, and may need to be worn all day and all night initially. Once your TMJ pain begins to go away, your dentist will come up with a treatment plan for long-term use, that most likely will not require wear throughout the day.
TMJ disorder can cause pain and discomfort in your jaw and face and should be addressed so that it doesn't get worse. This is a treatable condition that your dentist can help you handle with care at home.
One of the aspects of treatment is often wearing a mouth guard to help stop the pain from tooth grinding and to help your TMJ from getting worse.
You can purchase a mouth guard over the counter, you can order custom mouth guards online, or, in more severe cases, you may need to get a prescription mouthguard from the dentist.
You'll see a different range of mouth guard costs, depending on the kind you get, and you should always make sure to take good care of your mouth guard to prevent bacteria build-up and to make them last longer.
