“Lockjaw” usually means a condition where the jaw becomes stiff, painful, or hard to move. In everyday English, people also use it to describe a face or jaw that feels tight and won’t open normally.
People often use “lockjaw” when talking about a medical problem, especially tetanus, but it can also be used more loosely to describe jaw pain or tightness after an injury, dental issue, or muscle spasm.
Meaning & Usage
In medical language, lockjaw most often refers to tetanus, a serious illness that can cause the jaw muscles to tighten. In casual speech, someone might say they have lockjaw if their jaw feels stuck or painful.
Examples
“He could barely open his mouth because of lockjaw.”
“After the dental work, she had a bit of lockjaw for a day.”
Is lockjaw always tetanus?
No. It can refer to tetanus, but people also use it more generally for jaw stiffness or tightness.
Can lockjaw go away on its own?
If it is mild jaw stiffness, it may improve, but true lockjaw caused by tetanus needs urgent medical treatment.
Should I worry if I have lockjaw?
If your jaw is stuck, very painful, or you have trouble opening your mouth, it’s a good idea to see a doctor or dentist.
