Can Bad Oral Hygiene Cause Headaches?

Thursday, June 26, 2025

Headaches are a common complaint, affecting approximately one in six people in the United States. They’re often blamed on stress, dehydration, or poor sleep. But what if the source of your pounding head isn’t in your brain—it’s in your mouth? Can dental issues cause headaches? According to Penn Dental Medicine orofacial pain specialist Dr. Stefania Brazzoli, the answer is yes. Poor oral hygiene can lead to dental problems that contribute to headaches. Dr. Brazzoli explains the connection, diagnosis, and treatment options in this article and video.

Can Bad Oral Hygiene Cause Headaches? 5 Key Questions Answered

A young woman holds her hands to her temples and wonders if dental issues can cause headaches. While oral hygiene itself is not a direct cause of headaches, it does contribute to conditions that result in headaches. Issues such as dental infections, tooth decay, temporomandibular joint (TMJ) disorders, or teeth grinding can lead to orofacial pain, which is discomfort concentrated in the face and oral cavity, encompassing the mouth, jaws, and other related structures. Orofacial pain can radiate and manifest as headaches.

1. What Are the Most Common Causes of Orofacial Pain, and How Do They Relate to Headache Disorders?

“One of the most common causes of orofacial pain is temporomandibular disorders,” Dr. Brazzoli shares.

Temporomandibular joint (TMJ) disorder is a condition that affects the jaw joint and surrounding muscles, causing pain, discomfort, and difficulty with jaw movement. Common causes of TMJ include:

  • Jaw injuries.
  • Arthritis.
  • Teeth grinding and clenching.
  • Stress.
  • A misaligned bite (malocclusion).
  • Connective tissue disorders.

Other causes of orofacial pain include:

  • Dental issues such as infections, abscesses, or impacted teeth.
  • Nerve disorders such as trigeminal neuralgia.

2. How Does the Diagnostic Process for Orofacial Pain Differ From Other Pain Conditions?

A young woman holds her hand to her mouth while she talks to the dentist. “We have to evaluate the patient as a whole,” Dr. Brazzoli explains. “We have to work in combination with different specialties at a multidisciplinary level to actually assess and evaluate our patients.” This may require:

  • A thorough dental examination: Checking for dental problems, jaw alignment, and signs of bruxism.
  • A medical history evaluation: Understanding the patient’s history and frequency of headaches or facial pain.
  • Imaging studies: Assessing joint and dental health through X-rays, MRIs, or CT scans.
  • Referral to specialists: When necessary, referring patients to neurologists, ENT specialists, or pain management experts.

3. How Does Poor Oral Health Contribute to Headaches?

Poor oral health can lead to infections and inflammation in the gums, teeth, and jaw, which may subsequently contribute to headaches. Inflammation can cause blood vessels to dilate, including those in the head, resulting in headaches. And, chronic pain and discomfort can stress the body, inducing muscle tension and headache symptoms. “Muscle tension in particular can actually cause orofacial pain conditions,” says Dr. Brazzoli.

4. What Treatment Options Are Available for Managing Chronic Orofacial Pain and Headaches?

Effective management of chronic orofacial pain and related headaches generally involves a combination of treatments:

  • Dental Interventions: Addressing dental issues such as cavities, malocclusion, TMJ, or teeth grinding.
  • Pain Management: Using medications such as NSAIDs, muscle relaxants, or nerve blockers.
  • Physical Therapy: Following exercises and techniques to improve jaw function and relieve muscle tension.
  • Stress Management Techniques: Following cognitive-behavioral therapy or relaxation exercises.
  • Lifestyle Changes: Encouraging good sleeping posture and adequate oral hygiene.

5. What Role Does Stress Play in Exacerbating Orofacial Pain and Headaches?

“Stress plays a major role when it comes to orofacial pain. It affects every aspect of our life,” Dr. Brazzoli states. It is a significant factor that can exacerbate orofacial pain and headaches. Stress can lead to teeth grinding, increased muscle tension, and poor posture, all of which contribute to the cycle of pain. To manage stress effectively:

  • Practice relaxation techniques such as deep breathing, meditation, or yoga.
  • Establish a consistent exercise routine to manage stress and enhance overall well-being.
  • Seek professional help to address stressors.
