Trigger Point Series: Masseter – Could Jaw Pain or Toothache Be Coming From a Tight Muscle?

Do You Feel Tightness or Aching in Your Jaw?

Do you wake up with a sore jaw, notice yourself clenching your teeth during the day, or experience discomfort around your cheek or jaw joint?

The masseter is one of the main muscles responsible for closing the jaw and chewing. When this powerful muscle becomes tight or develops trigger points, discomfort may be felt not only in the jaw, but also around the cheek, teeth, ear, and temporomandibular joint (TMJ) area.

Sometimes what feels like a toothache or jaw-joint problem may have a muscular component.

Where Is the Masseter Muscle?

The masseter is a thick muscle located on each side of your face.

It runs from the cheekbone down to the lower jaw and helps you:

• Close your jaw

• Bite and chew food

• Stabilize the jaw during movement

You can easily feel it yourself.

Place your fingers on the side of your cheek just above the angle of your jaw, then gently clench your teeth. The muscle that becomes firm under your fingers is your masseter.

Because this muscle works every time you chew, bite, or clench, it can become overloaded when used excessively.

Common Symptoms of Masseter Trigger Points

Trigger points in the masseter may contribute to:

✅ Jaw pain or aching

✅ Tenderness in the cheek

✅ Pain around the TMJ area

✅ Discomfort near or around the ear

✅ Pain that feels like it is coming from the upper or lower teeth

✅ Jaw stiffness or fatigue

Some people may also notice:

• Difficulty comfortably opening the mouth

• Increased discomfort after chewing

• Facial tension

• Headaches around the temple

• Jaw soreness when waking up

Because tooth pain, ear pain, and jaw pain can have many different causes, persistent or severe symptoms should always be assessed by the appropriate healthcare professional.

What Causes Masseter Trigger Points?

The masseter commonly becomes tight because of:

• Teeth clenching

• Teeth grinding or bruxism

• Emotional stress

• Frequent gum chewing

• Biting hard or chewy foods

• Nail biting

• Holding tension in the jaw while concentrating

• Prolonged dental procedures

• Repetitive jaw movements

Many people clench their teeth without realizing it, especially while working, driving, exercising, or feeling stressed.

Over time, this repeated muscle contraction may contribute to fatigue and tenderness in the masseter.

Simple Masseter Relaxation Exercise

This gentle exercise can help you become more aware of unnecessary jaw tension.

Step 1

Sit comfortably with your shoulders relaxed.

Step 2

Allow your lips to rest together while keeping your upper and lower teeth slightly apart.

Step 3

Slowly open your mouth within a comfortable range.

Hold for 3–5 seconds, then gently close your mouth again.

Repeat 5–10 times.

Do not force your jaw open or stretch into pain.

A helpful reminder throughout the day is:

Lips together.Teeth apart.Jaw relaxed.

Gentle Self-Massage

Place two or three fingertips over the masseter on the side of your cheek.

Using light pressure, make small slow circles over the muscle for approximately 30–60 seconds.

Avoid pressing aggressively.

The jaw and facial muscles can be sensitive, and deeper pressure is not necessarily better.

If self-massage increases your symptoms, stop and seek professional advice.

How Massage Therapy Can Help

Registered Massage Therapists can assess whether tension in the masseter and surrounding muscles may be contributing to your discomfort.

Treatment may include:

• Trigger Point Therapy

• Therapeutic Massage

• Gentle compression

• Myofascial techniques

• Jaw and facial muscle work

• Neck and shoulder massage

• Gentle stretching

• Relaxation techniques

Your RMT may also assess nearby muscles such as the temporalis, sternocleidomastoid (SCM), upper trapezius, and other muscles of the neck and shoulders.

Jaw tension often occurs together with neck, shoulder, and facial muscle tension, so treatment may involve more than just the painful area.

When Should You Seek Professional Advice?

Jaw pain should not automatically be assumed to come from tight muscles.

See a dentist, physician, or other appropriate healthcare professional if you experience:

• Persistent or severe tooth pain

• Facial or jaw swelling

• Fever

• Jaw locking

• Significant difficulty opening your mouth

• Recent facial or jaw trauma

• Numbness or weakness

• Severe or worsening pain

• Symptoms that do not improve

Dental infections, tooth problems, TMJ disorders, and other conditions can sometimes produce symptoms similar to muscular jaw pain.
