Can toothache cause Headache and Eye pain?

Have you ever had a toothache that spread beyond your mouth? It may have caused you to have a headache or eye pain.

In this article, we’ll look at the connection between toothaches, headaches, and eye pain to better understand how these seemingly unrelated issues could be linked.

We usually think of oral health as just that, but there are some surprising connections between toothaches and other types of pain. We’ll explore the science behind it and talk about some solutions.

Toothache can cause headaches and eye pain. I saw many patients who felt migraines and pain in the ear as well when they had a toothache.

The trigeminal nerve is the reason behind this severe pain. If you want to know how, please read the entire article.

What is the Trigeminal Nerve responsible for?

According to the American Association of Neurological Surgeons, The trigeminal nerve is responsible for providing sensation to the face. It regulates the sensations of our eyes, nose, forehead, cheeks, lips, gums, jaw, and many other parts of the head.

Headaches or toothaches are detected by the same nerve, which is known as “the trigeminal nerve.” It is one of the biggest nerves in our heads.

Toothache and headaches are transmitted to the brain via this nerve. After reaching the skull, it divides into three branches:

  1. Ophthalmic Nerve
    • Maxillary Nerve
  2. Mandibular Nerve

The Toothache-Headache Connection

Nerve Pathways:

When a tooth becomes infected, inflamed, or experiences trauma, the nerves within the tooth send distress signals to the brain. These signals can travel along nerve pathways that are shared with the head and face, leading to the sensation of a headache.

Referred Pain:

Referred pain occurs when pain originating in one part of the body is felt in another. Dental experts suggest that the proximity of dental nerves to facial nerves can lead to referred pain, where a toothache is perceived as a headache due to overlapping nerve pathways.

Muscle Tension:

A toothache can cause individuals to clench their jaw or grind their teeth unconsciously. This increased muscle tension can trigger tension-type headaches that are felt across the forehead and temples.

The Eye Pain Connection

Nerve Interactions:

Just as dental nerves are connected to facial nerves, there are intricate connections between facial nerves and the nerves that serve the eyes. An intense toothache might stimulate these interconnected nerves, resulting in eye pain.

Sinus Involvement:

Some upper teeth share nerve pathways with the sinuses. An infected tooth can lead to sinus inflammation, which can cause pain around the eyes. This is particularly common with upper molars.

Inflammatory Response:

The body’s response to a tooth infection involves inflammation. Inflammation can spread and affect neighboring areas, including the eyes. This can result in discomfort and pain in and around the eyes.

How to Address the Issue

Consult a Dentist:

If you’re experiencing a toothache accompanied by persistent headaches and eye pain, it’s crucial to consult a dentist. They can diagnose the underlying dental issue and recommend appropriate treatment.

Addressing Toothaches:

Treating the toothache itself is essential to alleviating associated headaches and eye pain. Dental treatments such as root canals, fillings, or extractions may be necessary.

Pain Management:

In the interim, over-the-counter pain relievers can help manage the discomfort. However, these should not replace professional dental care.

Is it normal to have a Headache with a Toothache?

It’s normal to have a headache along with a toothache. The trigeminal nerve’s responsible for the connection, as it carries pain, touch, and all kinds of sensations to the brain.

So if you’re suffering from a toothache, it could cause a migraine, headache, and pain behind the eyes.

Referred pain is also a thing, which means the pain from one spot in the body can be felt in another, like the head with a toothache.

This headache usually feels dull, throbbing pain around the affected tooth and can spread to the temple or forehead.

The nerves in the face and head are complex, so dental issues like cavities, infections, or gum problems can activate them and cause pain to be interpreted as a toothache and a headache.

The body’s natural response to pain and inflammation can also worsen it.

If you’re feeling both, you should visit the dentist to treat the toothache and hopefully relieve the headache. You should see a dentist if the headache’s severe or won’t go away.

Why is My Toothache Making My Eye Hurt?

Eye pain and toothache can sometimes be linked due to interconnected nerve pathways in the face and head.

The pain signals from a dental issue, like a toothache, may radiate to the eyes, causing discomfort. Eye pain can have various causes, and not all toothaches are associated with eye pain.

If both symptoms occur, it’s advisable to consult with a dentist and an eye care professional to assess and address the symptoms.

Dentists should diagnose and treat dental issues, while eye pain may require an ophthalmologist or optometrist examination.

Seeking professional medical advice helps determine the specific causes and appropriate treatment.

How do you get rid of a Toothache Headache?

Mainly, these are two ways to get rid of a toothache & headache:

  1. Try to stop tooth pain at home
  2. Make an appointment with a dentist

It is a universal truth that most people first seek relief from various home remedies. If they don’t get relief from the pain, then they go to the dentist.

I’ll advise you to take dental problems seriously. If you have a toothache or a headache, you should absolutely see a dentist because it is crucial to understand the actual cause of pain.

Basically, pain is our body’s reaction. If something is wrong with us, the body will transmit warning signals to the brain. And ignoring those signals might throw us in danger.

How Do I Know if My Teeth Are Causing Headaches?

It is difficult to determine whether or not teeth are causing headaches. We should look for specific symptoms to determine the cause of the headache.

In order to determine whether teeth are causing headaches, you should observe these signs:

  1. Pressure on any particular tooth
  2. Severe pain with or without touch
  3. Swelling
  4. Sensitivity
  5. Pain behind eyes
  6. Numbness on the affected side


A toothache can lead to pain in other parts of your head, face, and even eyes – and it’s all connected by the trigeminal nerve.

That’s why figuring out what’s causing your headache is sometimes challenging. Don’t wait around if you’re feeling pain – see a dentist immediately to avoid severe consequences.

The link between toothache, headache, and eye pain isn’t as complicated as it may seem. The nerve and pathways in your head and face can result in referred pain.

If you’re feeling dental pain in your head and eyes, it’s essential to get it looked at and take care of the root cause to get some relief.


Can a tooth infection cause eye pain?

A severe tooth infection can spread bacteria, affecting nearby nerves that supply sensation to the eyes, causing eye pain.

Why does my toothache worsen when I have a headache?

Toothache and headache can exacerbate each other due to the shared nerve pathways and the potential for one type of pain to trigger the other.

Should I be concerned if my toothache spreads to my head and eyes?

Yes, it’s important to seek dental care promptly. The spread of pain indicates the involvement of interconnected nerves, which can affect your overall health.

How can I differentiate between a toothache-induced headache and a regular headache?

Toothache-induced headaches often have a localized source of pain (the affected tooth) that triggers the headache. Regular headaches might not have this dental connection.

Can eye strain cause toothaches?

While eye strain might not cause toothaches, it can contribute to overall discomfort and tension, indirectly affecting dental pain perception.
