An uncomfortable toothache can be an indicator that something is amiss with your mouth. While you might initially assume the problem is minor – such as poor ground ball hopoff at softball practice – or it could even be more serious.
The trigeminal nerve is one of the largest sensory nerves in your brain and helps control eye and facial movement sensations as well as feelings in your teeth, gums and jaw joints. Additionally, this nerve may trigger migraine attacks.
Can a Toothache Cause a Headache?
Toothaches can be the root cause of headaches. The trigeminal nerve, responsible for facial sensations including gums and teeth, establishes a direct link between toothaches and headaches. Additionally, teeth grinding or bruxism may lead to referred pain in the head.
Furthermore, reactions such as muscle clenching and jaw tightening due to toothaches also have the potential to trigger headaches.
When experiencing the pain of an abscessed tooth, it serves as a sign that there may be an issue with either your gums or tooth. Furthermore, this discomfort can even lead to a migraine. Neglecting obvious dental problems like a cracked tooth, exposed root, or untreated cavity may serve as triggers for such headaches.
If a toothache and headache occur simultaneously, it is essential to seek the expertise of a dentist. They can identify the root cause of the pain and administer appropriate treatment options.

Trigeminal Nerve
Toothaches can irritate the trigeminal nerve, which sends sensation from your cheeks, lips, teeth and jaw to your brain. When this cranial nerve becomes aggravated it may trigger migraines or radiate pain through your head and face. Issues related to dental hygiene like gum disease, jaw issues or malocclusion, untreated cavities/cracked teeth/impacted wisdom teeth may also contribute to head pain.
Bruxism, or teeth grinding at night, can cause headaches through clenching and grinding the teeth during sleep. The pain produced can manifest itself as migraine or headache symptoms described as one-sided and throbbing in nature; TMJ disorders or sinus infections could also be contributory factors.
Headaches are a frequent complaint that many people face; however there are ways to assess if your dental health contributes to them, including regular dental checkups to identify any contributing issues and address any possible dental concerns that arise.
Sinus Infections
Sinuses are four pairs of air-filled cavities in your facial bones near your eyes, forehead, and behind your cheekbones that serve to warm, moisten, filter, and warm the air you breathe through your nose. When these sinuses become inflamed or swollen, pressure and pain in your jaw may increase; often felt most acutely by upper back teeth close to these sinus passages.
Painful toothaches can worsen when moving your mouth or jumping up and down, as this disrupts sinus pressure distribution. Furthermore, high fever or chills could indicate more serious infection than just toothache alone.
To reduce pain, over-the-counter decongestant medication or antihistamines may help. Your physician may also prescribe antibiotics or suggest surgery in order to open your sinus passages.

TMJ Disorders
Medical News Today reports that many of the same factors that lead to headaches or migraines also play a part in dental issues, with nerve and muscle pain running from neck, face and jaw originating in nerve endings triggering headache pain followed by jawache pain; an agonizing cycle where head ache triggers jawache pain – sometimes in both directions simultaneously!
Wisdom tooth issues such as impacted or overcrowded wisdom teeth may contribute to headaches. Teeth grinding (bruxism), often due to stress or sleep deprivation, may also exacerbate headaches by wearing away enamel and straining jaw muscles.
If you are suffering from unexplained chronic headaches that are interfering with daily activities, it is wise to visit both a dentist and healthcare provider specializing in headaches or nerve conditions for diagnosis and advice regarding treatment.
Together they may come up with an individualized solution designed specifically to address your headache or nerve condition needs – even multiple methods may help provide relief from its painful throbbing sensation in head or jaw area.
Sleep Issues
Trigeminal nerve involvement in migraines is thought to play a vital role, leading to headaches with throbbing pain on one side of the head and accompanying nausea or sensitivity to light and sound. Medical experts speculate that dental issues like an infection or abscess could irritate this nerve and trigger migraine attacks.
Many are unaware that their dental health could be contributing to their headaches, according to a recent study published in PAIN journal. According to this research, headaches have been linked with oral and jaw issues like wisdom teeth impaction, cavities or misalignments as potential sources.
As part of having a dental condition, unknowingly clench your teeth or grind them at night while sleeping, which is known as bruxism. This condition also causes head pain that manifests itself either as dull ache around your scalp or behind the eyes.
What Are Some Other Dental Problems That Can Cause Headaches

Several dental issues can cause headaches, including:
- Tension headaches: Caused by muscle strain in head, neck, and jaw due to teeth grinding or misaligned bite.
- Tooth damage: Cracks, chips, and cavities exposing sensitive nerve tissue can cause pain.
- Temporomandibular joint (TMJ) disorder: Affects jaw joints and muscles, leading to jaw, face, and head pain, including headaches.
- Abscessed tooth: Severe infection causing pain and swelling in gums and jaw, radiating to the head.
- Bruxism: Grinding or clenching teeth, especially during sleep, causing muscle tension and head, neck, and jaw pain, leading to headaches.
If an individual is experiencing a headache alongside any dental problems mentioned, it becomes crucial to seek professional dental care. By doing so, one can determine the underlying cause of the pain and receive suitable treatment from a qualified dentist.
How Can You Treat a Toothache That Is Causing a Headache
If someone is experiencing a toothache that causes a headache, there are various methods available to alleviate the pain. Here, we provide some useful tips for relief:
- Gentle massages: Relax head, face, and jaw muscles to ease dental headache tension.
- Cold compress: Apply to painful face side to reduce toothache pain and inflammation.
- Antibiotics: If caused by infection, use antibiotics to clear infection and ease pain.
- Dental treatment: Address the cause with abscess cleaning, gum treatment, root canal, or extraction.
- Pain relievers: Use ibuprofen or acetaminophen to relieve toothache pain and inflammation.
See a dentist to determine the cause and get proper treatment for toothache with a headache.
What Are Some Home Remedies for Toothaches and Headaches
Applying a cold compress to the affected area has the potential to alleviate discomfort and decrease swelling, as it numbs the pain.
In times of mouth discomfort, a helpful approach is to gargle with warm saltwater. This simple practice aids in reducing inflammation and eliminating bacteria in the oral cavity, imparting temporary relief.
Peppermint tea offers a soothing solution for toothaches. Its numbing properties can effectively alleviate the pain. One can choose to drink peppermint tea or apply a soaked cotton ball with peppermint oil directly to the affected tooth for relief.
Garlic possesses powerful antimicrobial properties and can alleviate pain. One can easily prepare a treatment by crushing a fresh clove of garlic, mixing it with a pinch of salt, and gently applying the mixture to the affected tooth. Another effective method involves chewing on a piece of fresh garlic or utilizing garlic oil on a cotton ball for application.
Clove oil possesses analgesic and antibacterial properties, making it an effective remedy. For temporary relief, simply apply a small amount of clove oil to the affected tooth or use a cotton ball soaked in this powerful oil.
Vanilla extract possesses anti-inflammatory properties and can effectively alleviate the discomfort of a toothache by numbing the affected area. Applying a small quantity of vanilla extract to the site in question multiple times throughout the day can offer relief.
Hydrogen peroxide rinse can provide relief for tooth-related pain and inflammation when mixed with water. This solution serves as an alternative to a saltwater rinse.
It should be noted that these home remedies only offer temporary relief and cannot replace professional dental care. If the pain persists or worsens, it is highly recommended to seek the expertise of a dentist for accurate diagnosis and appropriate treatment.
