Key Takeaways
- Tooth pain and headaches can share some of the same nerve pathways, so one can contribute to the other.
- Teeth grinding, TMJ disorders, oral infections, and sinus infections are common causes of tooth pain and headaches.
- Pain that worsens when biting or matches a sore tooth is a sign the source may be in your mouth.
- Cold compresses and over-the-counter pain relievers can offer short-term relief.
- A dental visit is a good idea when tooth pain lasts more than a few days.
You wake up with a pounding headache and assume it’s stress or a rough night of sleep. But what if the real source is right inside your mouth? It’s more common than you might think for tooth pain and headaches to show up together, and knowing the connection can save you a lot of guesswork. At Bridgeland Dental Care, our team sees this combination regularly, so we’re always ready to help you figure out what’s going on.
Yes, tooth pain can cause headaches. The nerves in your teeth, face, and head are all connected, so pain that starts in a tooth can travel and show up somewhere that feels completely unrelated. If you’ve been dealing with nagging pain, we’d love to see you for a visit.
The Link Between Tooth Pain & Headaches
Your body has a large nerve called the trigeminal nerve. It runs through your teeth, jaw, face, and head. When something goes wrong in your mouth, that nerve can carry pain signals upward, making it feel like a headache when the source of the problem is a tooth.
This is called referred pain, and it can sometimes be hard to get a diagnosis because where you feel the discomfort and where the problem actually is don’t always line up.
Common Causes of Tooth Pain & Headaches
Tooth Infection & Abscess
A tooth infection or dental abscess can sometimes cause more than just pain in the affected tooth. As pressure builds from inflammation, the discomfort can spread through nearby nerves and tissues, sometimes leading to a persistent headache or pain that can spread into your jaw, ear, or face.
Unlike sensitivity that comes and goes, pain from an infection often lingers or becomes more intense over time. You might also notice swelling around the tooth or gums, a bad taste in your mouth, or discomfort when biting down. Because dental infections don’t typically resolve on their own and can worsen if left untreated, it’s important to see a dentist as soon as possible if you notice these symptoms.
Teeth Grinding
Grinding your teeth, sometimes called bruxism, puts a lot of strain on your jaw muscles. That tension doesn’t always stay in your jaw. Instead, it spreads into your temples and the sides of your head, which can lead to a dull, persistent headache by morning.
The tricky part is that many people grind their teeth while they sleep and have no idea it’s happening. A few signs to watch for include waking up with a sore jaw, headaches that show up early in the morning, and teeth that feel worn or sensitive. Night guards and other treatments can help relieve pressure on your jaw while you sleep.
TMJ Disorders
Your temporomandibular joint, or TMJ, is the hinge that connects your jaw to your skull. When this joint isn’t working properly, it can cause pain that spreads to your temples, ears, and head.
A clicking or popping sound when you open your mouth is one of the more noticeable signs. Pain that gets worse when you chew, yawn, or open your mouth wide is another. If that sounds familiar, a dentist in Calgary can take a closer look at what’s going on with your jaw and recommend treatment options.
Sinus Infections
Your sinuses sit just above the roots of your upper back teeth. When those sinuses get infected or inflamed, the pressure can feel a lot like a toothache, and it can also cause a heavy, throbbing sensation in your head. This one can be especially confusing because the pain can feel like it’s coming from your teeth, but it actually isn’t.
How to Tell if Your Headache Comes from a Tooth
Signs & Symptoms to Look For
There are a few patterns that can sometimes point toward your discomfort being caused by a dental problem. Pay attention to where the pain is and what triggers it. Here are a few other signs to look out for:
- Your headache is on one side and matches the location of a sore or sensitive tooth
- Biting down or chewing makes the pain flare up
- A tooth reacts to hot drinks, cold foods, or direct pressure
If these sound familiar, we recommend scheduling an appointment with our team.
Signs You May Need More Than Dental Care
Not every headache has a dental cause. If a dentist checks your teeth and finds nothing wrong, the source may be elsewhere. Headaches that come with nausea or sensitivity to light are more typical of migraines and may be worth discussing with your family doctor. If your headache is sudden and severe, comes with confusion, weakness, trouble speaking, vision changes, fainting, a stiff neck, or a high fever, seek emergency medical care.
When to Visit a Dentist in Calgary
Some tooth pain fades on its own, but there are times when waiting isn’t the right call. Reach out to our dental team if you notice any of the following:
- Tooth pain that has lasted more than a few days without improving
- Swelling in your face or gums, or a fever alongside the pain
- A jaw that clicks, grinds, or feels stiff and hard to open fully
These are signs that something may need attention sooner rather than later. A dentist can figure out what’s causing the discomfort and talk you through your options. If the pain is sudden or severe, our dental emergency page has details on when to seek urgent care.
Ways to Ease the Pain at Home
Quick Relief Options
If the pain has been persistent or hasn’t gotten better on its own, don’t keep waiting. Book a dental visit so the problem doesn’t have time to get worse. While you’re waiting for your appointment, a couple of simple measures can take the edge off the pain.
Try over-the-counter pain relievers like ibuprofen or naproxen to help reduce inflammation and dull the pain, if appropriate for you and as directed on the label. A cold compress held against your jaw or forehead for 15 minutes at a time can also bring some relief.
It’s generally important to continue brushing and flossing gently to help maintain your oral health while you wait for your appointment. If chewing makes the pain worse, we recommend sticking to soft foods until your appointment.
