By Dr. Javier Cutino, DMD · April 29, 2026 · 7 min read
Sudden jaw pain or a jaw that will not open fully can be alarming and confusing. Here is how to tell whether it is a TMJ flare-up, a dental infection, or something else, and when to see an emergency dentist in Coral Gables.

Understanding the Jaw Joint and Why It Flares Up
The temporomandibular joint, commonly called the TMJ, connects the lower jaw to the skull and allows chewing, speaking, and yawning. Because it is a complex joint involving cartilage, muscle, and ligaments, it can become inflamed or irritated from a range of causes, including teeth grinding, jaw clenching, stress, misaligned bites, and even prolonged wide-mouth activities like a long dental procedure.
A TMJ flare-up can happen suddenly, sometimes overnight, leaving a person waking up with a jaw that clicks, pops, or aches when chewing. For many patients in Miami, stress and clenching are significant contributing factors, and flare-ups often coincide with periods of poor sleep or high tension.
Understanding what triggers these episodes helps patients recognize whether their current pain is a familiar TMJ pattern or something new and potentially more serious, like an infection or injury.
TMJ Flare-Up or Dental Emergency: How to Tell the Difference
TMJ pain typically centers around the jaw joint itself, near the ears, and often comes with clicking, popping, or a feeling of the jaw catching when opening wide. Pain frequently worsens with chewing tough foods and may radiate to the temples or neck.
A dental infection, by contrast, usually centers on a specific tooth or area of the gums, often accompanied by swelling, sensitivity to temperature, or a visible abscess. If jaw pain is paired with facial swelling, fever, or pain that seems to come from one particular tooth rather than the joint area, it is more likely a dental infection requiring urgent treatment rather than a TMJ issue.
When in doubt, an emergency dentist in Coral Gables can examine both the teeth and the jaw joint to pinpoint the true source, since treating the wrong cause delays relief and can allow an underlying infection to worsen.
What Lockjaw Really Means and Why It Needs Attention
The term lockjaw is often used loosely to describe any jaw that will not open or close fully, but true lockjaw refers to a jaw muscle spasm that severely restricts movement, sometimes related to TMJ disorders, muscle strain, or in rare cases a serious infection affecting the jaw muscles. A jaw that suddenly gets stuck open or closed and will not release on its own should be treated as an urgent situation.
Patients experiencing a jaw that is genuinely locked, meaning it cannot move at all rather than simply being painful to move, should seek same-day evaluation. In many cases, gentle manipulation and muscle relaxation techniques from a dentist can resolve an acute locked jaw, but the underlying cause still needs to be addressed to prevent recurrence.
Because the jaw muscles and dental structures are closely connected, a dentist familiar with TMJ disorders is often the right first call for sudden jaw locking, rather than waiting to see if it resolves on its own over several days.
Home Steps to Ease a Jaw Pain Flare-Up
While waiting for a same-day appointment, a few simple measures can reduce discomfort without masking symptoms that a dentist needs to evaluate.
- Apply a warm compress to the jaw muscles for fifteen minutes to ease tension, or a cold pack if there is visible swelling.
- Stick to soft foods like eggs, soup, and smoothies to avoid overworking the jaw joint.
- Avoid wide yawns, chewing gum, and biting into hard or chewy foods until the flare-up subsides.
- Practice gentle jaw stretches only if they do not increase pain, and stop immediately if the jaw feels like it is catching.
- Consider an over-the-counter anti-inflammatory as directed on the label to reduce swelling and discomfort.
When TMJ Pain Signals a Larger Problem
Occasional mild jaw clicking is common and not always a cause for concern, but certain patterns suggest the issue needs professional evaluation rather than home management alone. Frequent locking episodes, pain that persists for more than a week, or jaw pain paired with headaches, ear pain, or difficulty fully opening the mouth all warrant a dental visit.
Chronic teeth grinding, often worse during stressful periods, is one of the most common underlying causes of recurring TMJ flare-ups seen in patients throughout Coral Gables, Brickell, and Downtown Miami. A custom nightguard is frequently recommended to protect the teeth and reduce strain on the jaw joint overnight.
Left unaddressed, chronic TMJ strain can also contribute to worn or fractured teeth over time, which is another reason why recurring jaw pain deserves a proper dental evaluation rather than repeated at-home management.
How an Emergency Dentist Treats Jaw Pain and Lockjaw
During an emergency visit for jaw pain, the dentist will examine the range of motion in the jaw, check for clicking or popping, palpate the jaw muscles, and take X-rays if a dental cause is suspected. Treatment may include gentle manual techniques to release a locked jaw, recommendations for a soft food diet, muscle relaxants, or anti-inflammatory medication for acute flare-ups.
For recurring issues, the dentist may discuss longer-term solutions such as a custom nightguard, bite adjustment, or referral for further evaluation if the joint itself shows signs of structural damage. The goal of the emergency visit is both immediate relief and identifying whether ongoing management is needed to prevent future flare-ups.

Frequently Asked Questions
What is the difference between TMJ pain and a toothache?
TMJ pain centers around the jaw joint near the ears and often includes clicking or popping, while a toothache is usually localized to a specific tooth, sometimes with swelling.
Is lockjaw a dental emergency?
Yes, a jaw that is genuinely stuck open or closed should be evaluated the same day, since a dentist can often relieve the spasm and identify the underlying cause.
Can stress cause jaw pain?
Yes, stress commonly leads to teeth grinding and jaw clenching, which are major contributors to TMJ flare-ups.
What can I do at home before seeing a dentist for jaw pain?
Apply warm or cold compresses, eat soft foods, avoid wide yawning or chewing gum, and use an over-the-counter anti-inflammatory as directed.
Does a nightguard help with recurring jaw pain?
A custom nightguard can reduce nighttime grinding and clenching, easing strain on the jaw joint and helping prevent recurring flare-ups.
