A toothache is pain that you feel in or around your tooth. Most often, toothache pain is a sign that there’s something wrong with your tooth or gums.
Sometimes, however, toothache pain is referred pain. That means the pain is caused by a problem elsewhere in your body.
You should never ignore toothaches. Toothaches caused by tooth decay can get worse if left untreated.
Toothaches are usually not life-threatening, but in some cases, they can be signs of serious conditions that require immediate medical treatment.
Toothache pain can range from mild to severe, and it may be constant or intermittent.
You may feel:
Common causes of toothaches
Tooth decay is the most common reason for toothaches. If tooth decay goes untreated, an abscess can develop. This is an infection near your tooth or in the pulp inside your tooth.
See your dentist right away if you think you have a dental abscess. In rare cases, the infection can spread to your brain, which can be life-threatening.
A toothache can also be caused by an impacted tooth. This happens when one of your teeth, usually a wisdom tooth, is stuck in your gum tissue or bone. As a result, it can’t erupt, or grow in.
Common causes of referred pain toothaches
Sinusitis is a condition in which your sinuses become inflamed due to a viral, bacterial, or fungal infection in your sinus cavity.
Because the roots of your upper teeth are close to your sinuses, sinusitis can cause pain in your upper teeth.
Less common causes of referred pain toothaches
Heart and lung disease can cause toothache pain due to the location of your vagus nerve. This nerve runs from your brain to the different organs in your body, including your heart and lungs. It passes through your jaw.
Rare causes of referred pain toothaches
These nerves service your skull, face, and teeth. When they become inflamed, pain can feel like it’s coming from your teeth.
Toothaches usually require medical treatment. Home treatment may temporarily relieve your pain while you wait for your dentist or doctor’s appointment.
Most people go to a dentist for a toothache, since most toothaches are caused by problems with your teeth.
Your dentist will use X-rays and a physical exam of your teeth to detect tooth decay or other dental problems. And they may give you pain medication and antibiotics to treat an infection.
If your toothache is due to tooth decay, your dentist will remove the decay with a drill and fill the space with dental materials. An impacted tooth may require surgical removal.
If your dentist can’t find the cause of your toothache, they may refer you to a doctor for further diagnosis and treatment.
Your doctor may treat sinusitis with antibiotics or decongestant medications. In rare cases, you may need to undergo surgery to open your nasal passages. In this case, your doctor will refer you to a specialist.
Treatment for trigeminal neuralgia and occipital neuralgia
There’s no cure for these conditions. Treatment usually consists of relieving your pain with medications.
Treatment for heart attack, heart disease, and lung cancer
If your dentist suspects that you’re having a heart attack, they’ll send you to the emergency department. If your dentist suspects that you have heart or lung disease, they’ll refer you to a doctor for further testing.
Things that may help temporarily relieve your tooth pain include:
- over-the-counter (OTC) pain medication, such as aspirin
- OTC topical dental pain medication, such as benzocaine (Anbesol, Orajel)
- OTC decongestants, such as pseudoephedrine (Sudafed), if your pain is due to sinus congestion
- clove oil applied to your aching tooth
Check with your doctor or dentist before using any product with benzocaine. Children under 2 shouldn’t use any products containing benzocaine.
Seek emergency treatment if you have the following symptoms, along with a toothache:
To help prevent toothaches, brush and floss your teeth at least twice a day and get dental checkups and cleanings twice a year, or as often as recommended by your dentist.
You can help keep your heart and lungs healthy by not smoking, eating a low-fat and high-fiber diet, and exercising at least 30 minutes a day, 5 times a week. Get your doctor’s permission before starting an exercise routine.
