If you have TMJ pain, jaw clicking, headaches, or you’re grinding your teeth at night, it can be tempting to jump online and order a night guard. They’re inexpensive, convenient, and promise to “protect your teeth.”
But here’s the problem: your jaw is part of a biological system, not an isolated body part. Putting a piece of plastic between your teeth without understanding what is driving the problem is treating the symptom, not necessarily the cause.
Bruxism and TMJ dysfunction can have MANY contributing factors. Your bite and occlusion matter, but so do your airway, nasal breathing, tongue posture, cervical spine, muscular tension, nervous system, sleep quality, stress physiology, and even the structural relationship between your jaw and skull.
If you simply cover the teeth without evaluating these factors, you may be protecting the enamel while completely missing the reason your jaw is working overtime in the first place.
Also… not all night guards are created equal. The thickness, material, design, where the contacts are placed, and whether the appliance is designed for your specific bite can all influence how your jaw muscles and joints function. Your teeth aren’t just chewing tools, they are part of a sensory system that provides your brain with constant information about where your jaw is in space. Changing that input can change how the entire system responds.
