Lady with jaw pain


The pain caused by temporomandibular joint (TMJ) disorders can bring great difficulty and discomfort to your everyday life.

From intense headaches to distracting tinnitus, the symptoms of temporomandibular disorders are often overwhelming.

Dr. Goodman can make you a nightguard to help with clenching and grinding while sleeping at night. 

Many patients understandably confuse TMJ and TMD. However, they're not interchangeable. Here's what they mean.

​The Consequences of TMD

TMJ problems like clenching and grinding can inflame or tighten your jaw muscles, leading to jaw and dental pain.

Temporomandibular joint problems can have far-reaching consequences, leading to the degeneration of your jaw joints.

TMD can even lead to cracks, chips, and widespread erosion in your teeth.

The symptoms of TMJ disorders can disrupt your daily life to an unbearable degree. 

A Closer Look at the TMJ

Although the exact causes of TMJ disorder are still being researched, TMD is generally related to factors like these.

Why Is TMD So Painful?

TMD results from the effects of strain, stress, and trauma to the temporomandibular joint.

When this jaw joint is strained, the jaw clenches and causes teeth grinding, muscle soreness, and inflammation. This leads to the blockage of circulation, build-up of lactic acid, toxins, and adhesions over time.

Those who have TMJ syndrome generally experience tenderness, weakness, soreness and mild to severe pain affecting daily life, especially sleep. They may experience jaw pain, dental pain, headaches, or a combination of all three.

TMD Has Lasting Effects

When the TMJ is strained, TMD generally progresses to grinding and results in heavy wear, sensitivity, soreness, chips, cracks, and breaking of the teeth.

While you may be able to temporarily decrease your temporomandibular joint discomfort with anti-inflammatory medication, you will likely need a long-term solution.

Dr. Goodman Can Alleviate Your TMD Symptoms With a Non-Invasive Option

The idea of TMJ surgery may seem daunting, but there is a non-invasive, non-surgical alternative: a custom NTI (nociceptive trigeminal inhibition tension suppression system) device.

The NTI device is a small, acrylic, clear mouth guard worn at night that fits between your front top and bottom teeth.

This TMJ treatment prevents the posterior teeth from contacting each other. The NTI device is designed to be worn long term to suppress and eliminate the reflex to clench and grind.

It can take just 10 to 15 minutes to create this strong mouth guard at our Kansas City office. Visit us to learn more about reducing TMJ grinding.

How Dr. Goodman Can Treat Your TMD

Our dentist, Dr. Goodman, can diagnose your temporomandibular disorder using X-rays and a description of your symptoms. Then, he can begin your TMD treatment with a custom mouth guard called an NTI device, made in minutes at his Kansas City practice.

Think of temporomandibular joint treatment as an investment in your future health.

Protect Your Teeth From the Effects of Temporomandibular Disorders

As a dentist, Dr. Goodman has seen the dramatic impact TMD can have on your teeth.

If left untreated, TMJ problems like bruxism (teeth grinding) can gradually wear down your enamel. TMJ disorders can also lead to broken teeth, which may be more susceptible to infections. In turn, that problem could require root canal therapy.

Unfortunately, the treatment costs for temporomandibular disorders can really add up. In fact, they may even lead to the need for tooth restoration or replacement if allowed to progress.

However, you do have options to treat your TMJ disorder. By acting proactively now, you may be able to prevent these serious problems with your custom NTI device.

A Common TMD Predicament: How Do I Know if I Grind My Teeth at Night?

You may think that you do not have a temporomandibular joint condition because you have never caught yourself grinding your teeth during the day.

For those with a temporomandibular disorder, though, this is common. Many people with bruxism grind their teeth in their sleep — which means they don't even know that they have a TMD.

If you wake up with tender, sore jaws or you experience increasing jaw joint pain during the day, you may have a TMD.

Dr. Goodman can help you pursue a diagnosis with X-rays and examine your teeth and jaw at our dental practice. They may be able to reveal evidence of your temporomandibular disorder.

What If My NTI Device Doesn't Resolve All My TMD Symptoms?

In the event that your NTI device does not fully treat your TMJ problems, you still have hope.

Dr. Goodman can talk with you about your case and your TMJ symptoms.

If more invasive TMJ disorder treatment is needed beyond the NTI device, then Dr. Goodman will refer you out to a specialist.

I Already Wear a Nightly Retainer — How Will That Impact My Treatment?

Wearing your retainer each night is crucial for your teeth to remain straight after braces. If you faithfully wear your retainer, then you already understand the importance of consistency, which can be incredibly beneficial for TMD treatment.

There's no need to stress if you need to also wear a NTI device. Simply alternate them, wearing your retainer one night and your NTI device the next. Your dentist, Dr. Goodman, can explain the benefits to you at your next dental visit.
