The Connection Between the Jaw and Pelvic Floor: A Surprising Link
When most people think of pelvic floor physical therapy, they often focus on the muscles in the pelvic region—those that support the bladder, bowels, and reproductive organs. However, it is important to look outside of the pelvis. One often overlooked relationship is that between the jaw and the pelvic floor. While these two areas may seem unrelated, they share an intricate connection through the body’s fascial system, nervous system, and overall muscle patterns. Understanding and investigating this connection can be a game-changer for anyone dealing with pelvic floor dysfunction.
Embryonic Development: A Shared Beginning
Both the jaw and the pelvic floor begin their development from the same embryonic tissue around the same time in gestation. This early connection sets the stage for the intimate relationship between these two areas of the body. Because they share developmental origins, they are naturally linked in structure and function, even into adulthood.
The Fascial System: A Web of Connection
The human body is connected by a complex network of fascia. Fascia is a dense connective tissue that surrounds muscles, organs, and other structures such as blood vessels and nerves. Think of fascia like a web that holds everything together. The fascial system forms a continuous connection from the head to the toes, which means that tension in one area of the body can influence other areas. After all, everything is connected!
The jaw, specifically the muscles around the temporomandibular joint (TMJ), and the pelvic floor are both part of this interconnected network. If tension or dysfunction occurs in the jaw, it can lead to tension in other areas of the body, including the pelvic floor. In fact, tightness in the jaw can often lead to muscle tightness in the pelvic floor and even contribute to issues like pelvic pain, urinary dysfunction, and constipation.
The Nervous System: A Shared Pathway
Both the jaw and the pelvic floor are innervated by branches of the same nervous system—the somatic nervous system—which controls voluntary muscle movement. The trigeminal nerve, which is responsible for sensations in the face and motor functions like chewing, shares a neural pathway with the pelvic floor through the sacral region of the spine.
When stress or tension builds up in the jaw, the body may respond by tightening other areas, including the pelvic floor. This is often seen in individuals with clenching or grinding habits, where the jaw muscles become overactive. Over time, this muscle tension may radiate down to the pelvis, contributing to tightness, discomfort, and dysfunction.
The Vagus Nerve: A Pathway of Influence
The vagus nerve, a cranial nerve, plays a critical role in regulating many bodily functions, including heart rate, digestion, and breathing. It runs from the jaw, through the sternocleidomastoid muscles in the neck, and travels down to the diaphragm and pelvic floor. Because the vagus nerve connects the jaw to the pelvic floor, issues in the jaw—such as tension or TMJ dysfunction—can impact the function of the pelvic floor, leading to symptoms like pelvic pain or incontinence.
The Dural Tube: The Connection from Brain to Tailbone
The dural tube, or dura mater, is a tough, protective membrane that surrounds the spinal cord, extending from the brain down to the tailbone. It acts like a casing for the nervous system. When there is tension in this structure—due to stress, poor posture, or injury—it can have a direct impact on the pelvic floor. The dural tube's role in transferring tension down the body means that stress in the jaw and neck area can cascade down to the pelvic floor, creating discomfort or dysfunction.
Stress: A Key Contributor to Tension
Stress is one of the most common contributors to jaw and pelvic floor dysfunction. Many people unknowingly clench their jaws or grind their teeth under stress, which leads to tension in the facial muscles, jaw, and the deep fascial line connecting the jaw to the pelvic floor. This tension can lead to pelvic floor overactivity, causing symptoms like pelvic pain, urinary urgency, or constipation. Since both areas are responsive to stress, it’s important to address the underlying causes of tension to restore balance.
How Do I Know If I Have Tension in My Jaw?
TMJ dysfunction can cause a range of symptoms, many of which might go unnoticed or be mistaken for other issues. Common signs of TMJ dysfunction include:
Jaw pain or tenderness, especially when chewing, talking, or yawning
Clicking or popping sounds when moving the jaw
Limited jaw movement, such as difficulty opening or closing your mouth fully
Headaches or earaches, often felt on the same side as the jaw discomfort
Teeth grinding or clenching, particularly at night
Neck and shoulder pain, as tension can spread from the jaw area
How Jaw Tension Impacts Pelvic Floor Health
Muscle Tightness and Dysfunction: If you experience jaw clenching, teeth grinding, or TMJ dysfunction, it can create a cascade effect of tightness and overactive muscles throughout the body, including the pelvic floor. This tension can lead to pelvic pain, discomfort during intercourse, urinary urgency, and even difficulty relaxing the pelvic floor muscles when needed.
Breathing Patterns: Proper breathing is essential for pelvic floor health. When you breathe, your diaphragm moves downward, which helps engage the pelvic floor muscles in a balanced way. However, jaw tension can interfere with proper breathing mechanics, leading to shallow or chest-based breathing. This, in turn, can affect how the pelvic floor muscles function and contribute to pelvic floor dysfunction.
Postural Changes: Jaw tension can lead to postural imbalances, which may affect the alignment and function of the pelvic floor. For example, a person who habitually clenches their jaw may develop forward head posture or rounded shoulders. These postural shifts can alter the alignment of the pelvis, placing more strain on the pelvic floor muscles and contributing to dysfunction.
How Pelvic Floor Physical Therapy Can Help
As pelvic floor physical therapists, we recognize the importance of a holistic approach when treating pelvic floor dysfunction. TMJ dysfunction, jaw clenching, or teeth grinding may have ripple effects on pelvic floor health, and addressing both areas simultaneously can provide relief. Treatment may involve manual techniques that target the jaw, neck, and pelvic floor muscles, as well as postural exercises, relaxation techniques and stress management strategies.
Incorporating breathwork and relaxation exercises can also be helpful in reducing tension in both areas. The vagus nerve, which connects the jaw and pelvic floor, can be stimulated to help relax both regions. By treating the body as a whole system, physical therapists can help alleviate symptoms and restore optimal function in both the jaw and pelvic floor.
Conclusion
The connection between the jaw and pelvic floor is a prime example of how our bodies function as a unified system. By understanding the link between these two areas, you can take a more holistic approach to pelvic floor health and tackle the root causes of dysfunction. If you're dealing with pelvic floor issues and suspect jaw tension may be contributing, consider working with a pelvic floor physical therapist who can help you address the full-body connection and guide you toward lasting relief.
