咬肌怎么了

Masseter

面颊/下颌极常见

原图集里没有这块肌肉，这一块是顺着颅骨补上的，可以直接点。

这块肌肉是什么

连接颧弓与下颌骨的强大咀嚼肌，是人体单位面积力量最强的肌肉之一，负责上提下颌（闭口咬合）。

为什么会不舒服

压力导致无意识磨牙和咬紧牙关；长时间咀嚼坚硬食物；颞下颌关节不适；夜间睡眠磨牙；单侧咀嚼习惯。

常见不适表现

面颊酸胀或疼痛；晨起下颌僵硬；张口或闭口时关节弹响；太阳穴头痛；牙齿磨损；耳前区疼痛。

缓解方法

拇指在颧弓下方的咬肌处做深压按摩；热敷面颊；口腔科制作咬合垫（夜间磨牙者）；白天保持牙齿轻微分开的放松姿势。

Masseter

Cheek and jaw · Very common

This muscle wasn’t in the original atlas. It was added along the skull, and you can tap it.

What this muscle is

A powerful chewing muscle from the cheekbone to the jaw. One of the strongest muscles in the body for its size. It lifts the jaw to close and bite.

Why it gets uncomfortable

Stress leading to unconscious grinding and a clenched jaw; chewing hard food for a long time; discomfort in the jaw joint; grinding in your sleep; a habit of chewing on one side.

How it usually feels

A sore ache or pain in the cheek; a stiff jaw on waking; clicking when you open or close; headache at the temple; worn teeth; pain in front of the ear.

What helps

Deep pressure with the thumb on the masseter just under the cheekbone. Heat on the cheek. A dental bite splint if you grind at night. Through the day, keep the teeth slightly apart.
