Painful jaw clicking, or locking caused by temporomandibular joint disorders (TMD) can disrupt your daily life in ways that are hard to ignore. While many people find relief through physical therapy, lifestyle changes, or medication, some cases require additional support to manage ongoing symptoms.
Hyaluronic acid injections are one of several tools orofacial pain specialists may use to address persistent TMJ derangement disorders. By supplementing the joint’s natural lubrication, these injections can help reduce friction, improve movement, and support joint health over time. Though not a cure-all, they may be an important part of a comprehensive approach to managing TMD symptoms, particularly in cases of inflammation or osteoarthritis. Here’s a look at how this treatment works and when it may be helpful for those with TMD.
What Is Hyaluronic Acid, and How Does It Help the TMJ?
Hyaluronic acid (HA) is a naturally occurring substance in the body that plays a key role in lubricating joints and tissues. In the temporomandibular joint (TMJ), it helps maintain smooth movement by reducing friction. However, in cases of TMJ disorders, such as osteoarthritis or joint inflammation, the natural production of hyaluronic acid may decrease, leading to increased friction, pain, and restricted movement.
In these cases, hyaluronic acid injections can provide relief by replenishing the joint’s natural lubricating fluid, reducing friction, and improving overall joint function.
When Are Hyaluronic Acid Injections Used for TMJ?
Hyaluronic acid injections are generally considered when other conservative treatments, such as physical therapy or anti-inflammatory medications, have not provided sufficient relief. Some of the specific conditions where HA injections may be helpful include:
Painful Clicking or Locking Joints: If your TMJ painfully clicks, pops, or locks during movement, it could be due to insufficient lubrication or joint dysfunction. Hyaluronic Acid injections may help reduce friction and restore smoother movement.
Osteoarthritis of the TMJ: In osteoarthritis, the cartilage in the TMJ can break down over time, and the joint may lose its ability to produce adequate hyaluronic acid. By providing additional lubrication, HA injections can help reduce pain and protect the remaining cartilage.
Inflammation and Joint Degeneration: When the TMJ is inflamed, the body may produce hyaluronic acid with a lower molecular weight, which is less effective at lubricating the joint. Sodium hyaluronate, the form of HA used in injections, has a higher molecular weight, making it more effective at reducing friction and supporting the joint.
How Do Hyaluronic Acid Injections Work?
When hyaluronic acid is injected directly into the TMJ, it works by increasing the viscosity of the joint fluid, which helps to:
Reduce Friction: By restoring the joint’s natural lubrication, HA reduces the friction that can cause painful clicking, popping, or locking of the jaw.
Alleviate Pain: With less friction and better lubrication, many patients experience a decrease in pain and discomfort.
Improve Joint Function: The injection helps restore smoother movement, reducing the stiffness that often accompanies TMD.
Promote Cartilage Health: In cases of osteoarthritis, HA can help protect the cartilage from further wear and tear.
What to Expect with Hyaluronic Acid Injections
The procedure for receiving hyaluronic acid injections is relatively simple and minimally invasive:
Consultation and Assessment: An orofacial pain specialist will assess your condition and order necessary imaging to evaluate the TMJ. This ensures that injections are appropriate for your specific situation.
Injection Process: Hyaluronic acid is injected directly into the TMJ. The procedure is quick and typically takes just a few minutes.
Post-Treatment Care: After the injection, patients are often advised to perform jaw hinge exercises regularly. These exercises can help the joint integrate the hyaluronic acid and improve movement.
How Many Injections Are Needed?
Typically, a series of four injections is recommended, spaced about a month apart. These injections provide cumulative benefits, with each one helping to build on the effects of the previous. This approach can offer a more gradual and sustained improvement in joint function.
Considerations and Effectiveness
While hyaluronic acid injections can provide relief for some individuals with TMD, they may not be the right solution for everyone. It’s important to discuss the treatment with a board certified orofacial pain specialists who have advanced knowledge and expertise treating TMJ disorders to determine if it’s an appropriate option based on your symptoms and medical history.
In some cases, HA injections may be used in combination with other treatments, such as physical therapy, anti-inflammatory medications, and occlusal orthotics, to achieve the best results.
Conclusion
Hyaluronic acid injections are a treatment option for those dealing with TMJ pain, clicking, or locking. By replenishing joint lubrication and improving movement, these injections can provide significant relief for some patients, particularly when other treatments haven’t been effective. However, it’s important to consult with a board certified orofacial pain specialist to determine if hyaluronic acid injections are suitable for your specific condition.
