At Greenvale Dental Group, we encounter many patients that suffer from nerve damage in teeth. This condition can be quite debilitating if left unchecked, which is why we’ve written this article to tell you everything you need to know. 

How does nerve damage affect teeth?

Nerve damage in teeth occurs when the nerves that connect to your teeth become damaged or injured. The nerves in teeth are responsible for providing sensation, such as temperature and pressure, as well as detecting pain. If the nerves become damaged, it can lead to a variety of problems, including pain, sensitivity, and even tooth loss.

What causes nerve damage in teeth?

There are multiple factors that can cause damage to the nerves in the teeth. It is important that you get your teeth regularly examined. That way, if you have any of these conditions, we can address them before they present significant damage to your teeth.

Trauma or injury to the teeth

Trauma or injury to the teeth can lead to nerve damage in several ways, including;

  • If the teeth are subjected to a direct blow, the nerves within them can be damaged. The force of the impact can cause the nerves to stretch, compress, bruise or even tear.
  • If a tooth is fractured or dislocated due to trauma, the nerves within it can be compressed or severed.
  • A severe blow to the face or jaw can cause a fracture of the jawbone, which can damage the nerves that supply the teeth.
  • Trauma to the teeth can also cause a hematoma or blood clot to form within the tooth or surrounding tissues. The pressure from the hematoma can compress the nerves.

Tooth decay or infection

The bacteria that cause tooth decay or infection can produce acid that slowly erodes the enamel and dentin layers of the tooth, eventually reaching the pulp, where the nerves and blood vessels are located. Once the bacteria reach the pulp, they can cause an infection or inflammation that can damage the nerves in the affected tooth.

Grinding or clenching of teeth

When you grind or clench your teeth (a condition also known as bruxism), it puts pressure on the teeth and surrounding tissues, which can compress the nerves and cause damage over time. The constant pressure and friction can also wear down the enamel on the teeth, which can lead to tooth sensitivity and increased risk of decay. 

Additionally, bruxism can cause muscle spasms and tension in the jaw, which can contribute to nerve damage and pain.

Aging

As people age, their teeth become more susceptible to wear and tear, which can cause the protective layer of enamel to wear away. This can expose the sensitive inner layers of the tooth, including the nerves, to damage from acid, bacteria, and other substances.

Additionally, aging can cause changes in the blood supply to the teeth and gums, which can affect the health of the nerves. As the blood vessels become less efficient, the nerves may not receive adequate oxygen and nutrients, leading to damage and deterioration over time.

Aging can also increase the risk of other conditions that can lead to nerve damage in teeth, such as diabetes, heart disease, and certain medications that can affect nerve function.

What are the signs and symptoms of nerve damage in teeth?

There are various signs and symptoms that one experiences due to nerve damage in teeth. These include;

  • Pain, which is a common symptom of nerve damage in teeth. The pain may be constant or intermittent and can range from mild to severe.
  • Tooth sensitivity, in which the teeth may become more sensitive to hot or cold temperatures, sweet or sour foods, and pressure.
  • Numbness or tingling in the affected tooth or surrounding area.
  • Swelling of the gums or face.
  • The affected tooth becoming discolored, indicating that the nerve has died or become damaged.
  • Nerve damage making it difficult to chew or bite down properly.
  • Tooth mobility, where the tooth becomes loose and may eventually fall out.

How does a dentist diagnose and treat nerve damage in teeth?

At Greenvale Dental Group, we employ a range of methods to effectively diagnose and treat nerve damage in teeth. We can also lower your discomfort and prevent the damage from worsening.

Diagnosis

To diagnose nerve damage in teeth, we use the following methods;

Visual examination

A visual examination is one of the primary methods that we use to diagnose nerve damage in teeth. During a visual examination, we will examine the affected tooth and surrounding areas for any signs of damage or decay. We use a dental mirror, magnification and a bright light to get a better view of the tooth and look for any cracks, chips, or discolouration.

Dental X-rays

Dental x-rays can reveal signs of nerve damage that may not be visible during a visual examination, such as changes in the shape, size, structure of the teeth, roots and bones. During the X-ray process, we get you to bite down on a small piece of plastic or foam to help locate the affected tooth and identify the source of any pain or discomfort. This helps us get a more complete picture of your teeth and the damage affecting it.

Sensitivity tests

To determine the best course of treatment, we might present you with a series of sensitivity tests to determine the extent of your nerve damage. These tests include applying stimuli such as heat or cold, as well as slight pressure in order to assess the response on the teeth.

Treatment

The treatment for nerve damage in teeth depends on the severity and extent of the damage to the teeth. Methods of treatment include;

Root Canal Treatment

Root canal treatment is a common procedure used to treat nerve damage in teeth. During this procedure, the dentist will remove the damaged or infected nerve tissue from the tooth and replace it with a filling material. This can help to relieve pain and restore the tooth’s function.

Medications

Over-the-counter or prescription medications may be recommended to manage pain and inflammation associated with nerve damage in teeth.

Crown

We can place a dental crown over a tooth that has experienced nerve damage to protect the remaining tooth structure and prevent further damage.

Extraction

In severe cases of nerve damage or if the tooth cannot be saved through other means, extraction may be necessary. This involves removing the affected tooth and replacing it with a bridge, implant, or other dental restoration.

How can I prevent nerve damage in my teeth?

  • Brushing teeth twice a day
  • Flossing regularly
  • Visiting the dentist for regular check-ups
  • Wearing a mouthguard to prevent injury to teeth
  • Avoiding foods that are too hard or sticky
