10 Possible Causes of Toothache

Gail Miller • May 30, 2024

Toothache is one of those discomforts that can turn a good day into a miserable one. The pain can range from a mild annoyance to an excruciating throb that affects your ability to eat, sleep, and function normally. 


Understanding what might be causing your toothache is the first step toward finding relief. In this article, we’ll delve into 10 possible causes of toothache and discuss effective ways to address and alleviate this discomfort.


What Are the Most Common Causes of Toothache?

Toothaches can be caused by various factors, and it is important to identify the underlying cause to determine the appropriate treatment. The following are 10 common causes of tooth pain:


1. Dental Cavities

Dental cavities, also known as tooth decay, are one of the most common causes of toothache. Cavities occur when the enamel of the tooth is damaged by bacteria, leading to the formation of a hole or cavity. This can cause tooth pain, especially when eating or drinking hot or cold foods. 


Using fluoride toothpaste and practicing good oral hygiene can help prevent cavities. Regular dental check-ups and cleanings are also important for early detection and treatment of cavities.


2. Gum Disease (Gingivitis and Periodontitis)

Gum disease, including gingivitis and periodontitis, can also cause tooth pain. Gum disease occurs when the gum tissue becomes inflamed due to the buildup of plaque and bacteria. This can result in gum recession and tooth sensitivity. 


Proper brushing and flossing techniques, along with regular dental cleanings, can help prevent and treat gum disease. It is important to address gum disease early on to prevent further damage to the gums and teeth.


3. Tooth Root Sensitivities

Tooth root sensitivities occur when the inner layer of the tooth, known as dentin, becomes exposed. This can happen due to gum recession, tooth decay, or tooth enamel erosion.


When the dentin is exposed, it can cause tooth pain and sensitivity, especially when consuming hot or cold foods. Using toothpaste specifically designed for sensitive teeth can help alleviate the discomfort. 


In some cases, a root canal procedure may be necessary to treat the underlying cause of tooth root sensitivities.


4. Impacted Teeth

Impacted teeth, such as wisdom teeth, can also cause tooth and jaw pain. Wisdom teeth are the last set of molars to emerge, and they often do not have enough space to grow properly. 


As a result, they can become impacted, meaning they are trapped beneath the gum line. Impacted teeth can cause tooth and jaw pain, as well as swelling. In some cases, impacted teeth may need to be surgically removed to alleviate the pain.


5. Tooth Fractures

Tooth fractures can occur due to injury or biting into hard objects. They can cause sharp pain, especially when biting or chewing. Tooth fractures can vary in severity, and treatment options depend on the extent of the fracture. 


Minor fractures may be treated with dental bonding or fillings, while more severe fractures may require dental crowns or root canal therapy. Failing to treat tooth fractures can lead to further dental problems, including infection.


6. Damaged Fillings or Dental Work

Damaged fillings or other dental work can cause tooth pain. Fillings can become loose or damaged over time, leading to tooth sensitivity and pain. In some cases, the damaged filling may need to be repaired or replaced by a dentist. 


Prompt treatment can provide tooth pain relief and prevent further dental problems. Regular dental check-ups can help identify any issues with fillings or other dental work and address them early on.


7. Abscessed Tooth or Infection

An abscessed tooth or infection can cause severe toothache, which occurs when there is an infection in the root of the tooth, often due to untreated tooth decay or trauma. This can result in severe tooth pain, swelling, and even fever. 


An abscessed tooth requires immediate dental attention to treat the infection and alleviate the pain. Treatment may involve a root canal procedure or, in severe cases, extraction of the affected tooth.


8. Temporomandibular Joint Disorders (TMJ)

Temporomandibular joint (TMJ) disorders can cause jaw pain and discomfort. The TMJ is the joint that connects the jawbone to the skull. TMJ disorders can be caused by various factors, including injury, teeth grinding (bruxism), and arthritis. 


If you experience jaw pain, difficulty in chewing, and notice clicking or popping sounds in the jaw, they may be symptoms of TMJ. However, there are treatments you can get such as medication, physical therapy, and the use of dental appliances to alleviate pain and improve jaw function.


9. Clenching or Grinding Teeth (Bruxism)

Clenching or grinding teeth, also known as bruxism, can cause tooth pain and enamel damage. Bruxism often occurs during sleep and can be caused by stress, anxiety, or an abnormal bite. 


Over time, bruxism can wear down the enamel of the teeth, leading to tooth sensitivity and pain. Using a dental night guard can help alleviate the symptoms of bruxism by preventing tooth grinding and clenching.


10. Sinus Pressure Linked to Toothache

Sinus infections can sometimes cause toothache, especially in the upper teeth. The sinuses are located close to the upper teeth, and pressure from a sinus infection or inflammation can radiate pain to the teeth, causing a toothache. 


Other symptoms of a sinus infection may include nasal congestion and tenderness around the sinuses. Treating the underlying sinus infection can help alleviate the toothache.


Understanding the Symptoms: More Than Just Pain

Toothache symptoms can vary depending on the underlying cause. In addition to tooth pain, other symptoms may indicate gum disease or a dental abscess.


Recognizing Gum Disease Symptoms

Gum disease can cause toothache and other oral health problems if left untreated. Recognizing the symptoms of gum disease is important for early detection and treatment.


Symptoms of gum disease may include bleeding gums, especially during brushing or flossing, tender gums, and inflammation. 

Bad breath and receding gums are also common signs of gum disease. Regular dental check-ups and proper oral hygiene can help prevent and treat gum disease.


Identifying Symptoms of an Abscessed Tooth

Toothaches can be caused by various dental problems, and one common cause is an abscessed tooth. Symptoms of an abscessed tooth include a sharp, throbbing pain in the affected tooth, as well as swelling in the surrounding area. 


The pain may be constant or intermittent, and it may worsen when you bite down or apply pressure to the tooth. Other symptoms can include fever, a bad taste in the mouth, and swollen lymph nodes.


If you experience these symptoms, it's important to see a dentist as soon as possible for proper diagnosis and treatment. 


When to See a Dentist for Your Toothache

Knowing when to see a dentist about your toothache is important in preventing the issue from worsening and causing further dental problems.


In general, it's recommended to see a dentist if your toothache lasts for more than a couple of days or if the pain is severe. These may be signs of a dental emergency that requires immediate attention.


Signs Your Toothache Needs Immediate Attention

Some toothaches may require immediate attention from a dentist. If you experience any of the following signs, it's important to seek dental care as soon as possible:


  • Severe pain: If your toothache is accompanied by intense and unbearable pain, it may be a sign of a dental emergency. Severe pain can indicate an infection, abscess, or other serious dental issues that require immediate treatment.
  • Swelling: Swelling around the affected tooth or in the surrounding gums and face is a concerning sign. It can indicate an infection or abscess that needs to be addressed promptly to prevent further complications.
  • Difficulty in chewing or biting: If your toothache makes it difficult to chew or bite down on food, it may be a sign of a more serious dental problem that requires immediate attention.


If you experience any of these signs, it's important to contact a dentist as soon as possible to determine the underlying cause of your toothache and receive appropriate treatment.


Can Toothache Indicate A More Serious Health Issue?

Toothaches are often related to dental problems, but in some cases, they can indicate a more serious health issue. For example, tooth pain can be a symptom of a heart condition, such as angina.


It can also be a symptom of trigeminal neuralgia, a chronic pain disorder affecting the trigeminal nerve. If you have concerns about the underlying cause of your toothache, it's important to see a dentist for a proper diagnosis and, if necessary, get further medical evaluation.
