TMJ Disorders in Pets: What You Need to Know

Featuring Insights from Dr. Jin Jung, DVM

Ever seen your cat or dog with their mouth slightly open, unable to close it properly?

It might be more than just a silly face — it could be a temporomandibular joint (TMJ) disorder. While often overlooked, TMJ problems in pets can cause serious discomfort and require immediate attention.

Thanks to the research of Dr. Jin Jung, DVM, a veterinary dentist and oral surgeon in New York City, we now have a much clearer picture of how TMJ luxation (jaw dislocation) affects our pets — especially cats.

What Is TMJ Luxation?

TMJ luxation happens when the jaw joint gets dislocated, making it difficult or even impossible for the animal to close its mouth properly. 😬

Dr. Jung’s study, published in Frontiers in Veterinary Science, reviewed 21 cases of TMJ luxation in cats between 2000 and 2018 — one of the most comprehensive studies of its kind. 📘🐾

What Causes TMJ Luxation in Pets?

The main causes identified in the study were:

• 🐕 38% – Altercations with dogs

• 🚗 19% – Hit-by-car accidents

• 🪜 19% – Falls from heights

• ❓ 19% – Unknown causes

This breakdown shows how everyday incidents can lead to serious jaw trauma in cats even if the injury seems minor at first. 🐾

🚩 Clinical Signs to Watch For

Look out for these symptoms:

• 😾 Inability to fully close the mouth

• 💦 Excessive drooling

• 🌀 Jaw deviating toward the opposite side of the injury

But don’t jump to conclusions — these signs may also be seen in:

• 🦷 Tooth luxation

• 🧱 Maxillofacial fractures

• 🧬 Oral tumors

• 😮‍💨 Open-mouth jaw locking

That's why advanced imaging like dental radiographs or CT scans is essential to properly diagnose TMJ luxation.

🛠️ How Is It Treated?

According to Dr. Jung's findings:

 94.7% of cases saw successful jaw reduction!⏰ The sooner the jaw is repositioned, the better the outcome.

However, some cats did experience complications:

• 😬 24% – Developed permanent malocclusion (misaligned bite)

• 📉 5% – Had reduced jaw mobility

Fortunately, early intervention and proper care led to a very good prognosis overall. 🐱

Why This Matters for Pet Owners and Vets

Dr. Jung's research sends an important message: Any pet with head trauma should be fully evaluated for jaw injuries.

This includes:

• 🧑‍⚕️ Thorough oral and facial exam

• 🖼️ Dental radiography or CT imaging

• 📅 Prompt treatment planning

Ignoring or missing a TMJ luxation can lead to chronic issues — but catching it early can prevent long-term discomfort. 🩺🐾

💬 Final Thoughts

TMJ luxation is a serious but treatable condition. With fast action and expert care, our pets can recover and return to their purring, tail-wagging selves in no time! 😸🐶

Thanks to Dr. Jin Jung’s pioneering study, we now have a better understanding of TMJ disorders in cats and how to tackle them with confidence.

✨ Happy pets, healthy jaws! 🦷💛
