Toothaches can be extremely frustrating and sometimes challenging to diagnose. While a toothache is a pain generally experienced in the tooth, jaw, or cheek, it can also cause several other issues, including tight muscles. In some cases, the cause of a toothache may not be from the teeth at all but could be referred pain from trigger points in the muscles, ligaments, joints, or jaws. This is known as myofascial or muscular toothache. On the other hand, issues with the temporomandibular joint (TMJ) can also cause muscle spasms, twitching, and headaches.

What You'll Learn

Myofascial pain
The exact cause of myofascial pain syndrome remains unclear, although muscle overload due to overuse or disuse is believed to be a key factor. Other risk factors include trauma, poor posture, structural abnormalities, and systemic conditions such as vitamin D deficiency or hypothyroidism.
Treatment for myofascial pain syndrome aims to relieve pain and address underlying causes through pharmacological and non-pharmacological approaches. Pharmacological options include non-steroidal anti-inflammatory drugs (NSAIDs), muscle relaxants, and antidepressants. Non-pharmacological approaches include transcutaneous electrical nerve stimulation, ultrasound, and botulinum toxin type A (Botox).

Temporomandibular joint disorder (TMD)
Toothaches can be of muscular origin. Trigger points in the masticatory (chewing) muscles can sometimes refer pain to the teeth. This referred pain can be a source of confusion for both patients and clinicians. Myofascial pain is the most common form of Temporomandibular joint disorder (TMD). It results in discomfort or pain in the fascia (connective tissue covering the muscles) and muscles that control the jaw, neck, and shoulder function. TMD pain can affect the entire head and neck, including the teeth. While tooth-specific pain can occur when the TMJ muscles are working improperly, it can also be the result of cavities, enamel erosion, and more.
TMD headaches are often described as a ring of tension and pain. Beyond a headache, you may experience jaw or facial pain and tightness, restricted jaw movement, and changes in bite ability. TMDs can occur alone or at the same time as other medical conditions such as headaches, back pain, sleep problems, fibromyalgia, and irritable bowel syndrome. TMDs are twice as common in women than in men, especially in women between 35 and 44 years old.
In many cases, the actual cause of this disorder may not be clear. Sometimes the main cause is excessive strain on the jaw joints and the muscle group that controls chewing, swallowing, and speech. This strain may be a result of bruxism, which is the habitual, involuntary clenching or grinding of the teeth. Trauma to the jaw, head, or neck may also cause TMD. Arthritis and displacement of the jaw joint disks can also cause TMD pain.
When you first feel discomfort in your jaw joints or muscles, your doctor or dentist may recommend eating soft foods, applying heat or cold to the face in combination with exercises to gently stretch and strengthen the jaw muscles, and taking over-the-counter medications such as non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen. Experts strongly recommend staying away from treatments that cause permanent changes to the jaw joints, teeth, or bite, or that involve surgery.

Trigger points
Treating trigger points can provide relief from associated tooth pain. Strategies such as trigger point injection with local anesthesia into the affected muscle can decrease the toothache. Additionally, addressing both dental issues and muscle dysfunction through collaboration between dentists and physical therapists can achieve comprehensive outcomes.

Jaw issues
Toothaches are a common cause of jaw pain and can be due to cavities or abscesses. The pain from a toothache can spread to the jaw, leading to stiffness and soreness. Grinding your teeth, also known as bruxism, can also cause jaw pain and affect the temporomandibular joint and muscles. This can lead to inflammation and breakdown of the joints, resulting in stiffness and discomfort.
Temporomandibular disorders (TMDs) are a group of conditions that cause pain and dysfunction in the jaw joint and muscles that control jaw movement. TMDs can lead to jaw stiffness and pain, which may be mild or severe. The temporomandibular joint (TMJ) connects the jawbone to the skull and is responsible for opening and closing the mouth. Disorders of this joint can cause pain and stiffness in the jaw and surrounding areas.
In some cases, jaw stiffness may be caused by certain diseases or infections. For example, mumps can cause swelling of the glands on the side of the mouth, making it difficult to move the jaw. Tetanus, a bacterial infection, may also cause jaw stiffness as an early sign.
If you are experiencing jaw stiffness, it is recommended to consult a doctor or dentist for proper diagnosis and treatment. They may suggest over-the-counter medications, jaw exercises, or lifestyle changes to alleviate the stiffness and improve your quality of life.

Headaches
Toothaches and headaches can indeed be related. Several underlying dental and medical conditions can cause both toothaches and headaches. These include:
Dental Abscesses
Infections in the tooth or surrounding tissues can cause severe toothaches and headaches due to inflammation and pressure buildup. This pain can spread to the jaw, neck, and head.
Bruxism
Bruxism, or teeth grinding, can lead to muscle tension and strain, causing dental pain and headaches. The pain from bruxism is usually described as a dull, tight feeling around the head or behind the eyes. It often worsens with chewing or touching the face.
TMJ Disorders
Temporomandibular joint (TMJ) disorders occur when the jaw joint and surrounding muscles are not working properly, often due to stress, arthritis, or jaw injury. These disorders can cause tooth pain and headaches, with pain radiating to the jaw, temple, neck, or shoulders.
Cavities and Tooth Decay
Cavities and tooth decay can reach the inner layers of the tooth, causing sharp pain and sensitivity that may lead to headaches.
Sinus Infections
Sinus infections can cause both toothaches and headaches.
Migraines
While toothaches can trigger migraines, systemic inflammation from migraines can also worsen toothache symptoms.
The relationship between toothaches and headaches is often attributed to shared nerve pathways, especially the trigeminal nerve, which carries pain signals from the teeth and face to the head. Additionally, muscle tension caused by toothaches can lead to tension-type headaches.
If you are experiencing ongoing toothaches and headaches, it is important to seek dental care for a proper diagnosis and treatment.

Frequently asked questions
Yes, toothaches can cause stiff muscles. Toothaches can be caused by myofascial pain, TMD (Temporomandibular Joint Disorders), or problems with the jaw muscles or bones. This can result in stiff muscles in the neck and jaw.
A toothache is a pain experienced in the tooth, jaw, or cheek. It can be accompanied by a fever, headaches, tight muscles, inflammation, and ear pain. If the pain lasts for more than two days, it is recommended to see a dentist.
There are various treatment options available, including warm compresses, muscle relaxants, anti-inflammatory medications, physical therapy, and massage. Applying heat or cold to the affected area may also help.
