The Link Between Headaches And Your Teeth

Do you ever get a headache and can’t figure out why? It might be something as simple as your teeth.

Believe it or not, there is a link between headaches and your teeth. It may sound strange, but studies have shown a link between headaches and problems with your teeth or jaw.

In this blog post, we’ll discuss the link between headaches and teeth and how to fix it. We’ll also cover other causes of headaches so you can better identify what’s causing yours. So, if you’re looking for some relief from your chronic headaches, read on!

Most Common Types of Headaches and Their Causes

There are many types of headaches, and their causes can vary drastically. However, some types of headaches are more common than others. Here are a few of the most common types of headaches and their potential causes:

Tension Headaches

Tension headaches are the most common type of headache and are often caused by stress or muscle tension.

These headaches usually feel like a band tightening around your head and can be accompanied by pain in the neck or shoulders. A dental headache is a type of tension headache.

Cluster Headaches

Cluster headaches are much less common than tension headaches but tend to be much more severe. They are typically characterized by a sharp, piercing pain on one side of the head, often occurring in clusters or cycles.

Cluster headaches may be caused by changes in brain chemicals or nerve dysfunction.


Migraines are a type of headache often accompanied by symptoms like nausea, vomiting, and sensitivity to light. Several factors can trigger migraines, including stress, hormones, and certain foods.

What is a Dental Headache?

A dental headache is a type of tension headache that is caused by muscle contraction in the face, head, and neck. The pain is often worse when you chew or clench your teeth. It can also be aggravated by changes in temperature, such as cold air or wind.

Dental headaches are often accompanied by other symptoms, such as jaw pain, earache, and fatigue. While dental headaches are not dangerous, they can be extremely uncomfortable.

If you experience dental headaches regularly, you must see a doctor or dentist to rule out any underlying dental or medical conditions.

Dental Issues That Can Cause Headache Symptoms

Many dental problems can cause pain in the teeth, jaw, or face, leading to headaches. Some of these are:


When you have a cavity, it can cause the nerve endings in your tooth to become irritated. This can lead to pain radiating to the temples and forehead, causing headaches.

Misaligned Bite

A misaligned bite can cause headaches because it can strain the muscles of the jaw, face, and head. Additionally, misaligned teeth put pressure on the nerves and blood vessels in the head. All these can lead to tension headaches.

To prevent headaches caused by a misaligned bite, it is important to seek treatment from a qualified dental professional. In many cases, this can be corrected by Invisalign, other Invisalign alternatives, and other forms of dental treatments.

By aligning the teeth and correcting the bite, they can help alleviate the pain and discomfort associated with headaches.

Teeth Grinding

Teeth grinding, also called bruxism, is a common problem that can cause various problems, including headaches. Most people grind their teeth occasionally when stressed, but some do it more often, even during the day.

Teeth grinding can lead to muscle tension in your jaw, neck, and shoulders, which can cause headaches. If you suspect you may be grinding your teeth at night, talk to your dentist about ways to prevent or stop it.

There are several things you can do at home to help prevent teeth grinding, such as avoiding hard foods and chewing gum, and there are also treatments available from your dentist if the problem is severe.

TMJ Disorders

Temporomandibular Joint (TMJ) disorders can cause headaches for a number of reasons.

  1. They can cause the temporomandibular joint to become inflamed. This inflammation can then lead to pain in the muscles around the joint and in the jaw itself.
  2. They can cause the ligaments and tissues around the joint to tighten. This tightened tissue can then put pressure on the nerves in the area, leading to headaches.
  3. They can cause changes in bite alignment. This misalignment can lead to muscle tension and pain, which can contribute to headaches.

Tooth Infections

While tooth infections are often considered a dental issue, they can cause headaches. The nerves in the jaw are connected to the nerves in the head, so a jaw infection can cause headaches.

In addition, tooth infections can lead to swelling in the face, which can put pressure on the blood vessels in the head and lead to headaches.

If you have a tooth infection, treating the infection can help to relieve your headache symptoms.

Treatment Options for Dental Headaches

Several treatment options are available to help alleviate the pain of dental headaches and restore dental health.

  • Pain Medicines: For minor dental headaches, over-the-counter painkillers may be sufficient. For more severe pain, prescription medication may be necessary.
  • Treat the Root Cause: Treatment for the underlying cause of the headache (e.g., tooth decay or gum disease) will be required to prevent the headaches from returning.
  • Avoid Triggers: It is important to avoid trigger foods and beverages (such as caffeine and alcohol) and to practice stress-relieving techniques (such as yoga or meditation) to help prevent future headaches.

Final Thoughts

Headaches and teeth are often linked together. If you’re someone who suffers from headaches, you may find that your teeth are one of the main culprits.

If you’re struggling with chronic headaches, it might be time to talk to your dentist about the possibility of braces or other treatments. Who knows – you might just find relief from an unexpected source!
