How Powerful Is the Human Jaw?

You use your jaw to speak, chew, and smile. Did you know jaw muscles can contract with a force of 55 to 200 pounds of pressure? The impressive 200 pounds go for the back molars as force tapers off toward the front of the jaw.

Research has shown that those who suffer from bruxism, or chronic teeth grinding, can abnormally grow their jaw muscles from repetitive clenching at night. If you suffer from bruxism, the power in your jaw may be more than the typical numbers.

Your Jaw & Teeth

While the human jaw may be able to withstand a lot of pressure, the teeth that sit upon it are fragile. Despite tooth enamel being one of the hardest substances in the human body, it is delicate.

Healthy teeth can be chipped, cracked, or broken when the full force of the human jaw comes down. Additionally, teeth that are weakened from past cavities, infection, or other oral health problems are more at risk from the force of the grinding bite.

Caring for Your Jaw

The jaw can develop problems due to overuse and poor habits. One common problem is TMJ disorder, which can result in pain and dysfunction.

If you experience frequent pain or discomfort in your jaw, you might be suffering from TMJ disorder. A nightguard or other type of treatment may be necessary. Until you can get a protective guard, we recommend you: eat soft foods, regularly massage your jaw muscles, engage in relaxing activities to reduce overall anxiety, and avoid chewing gum.
