Pulp necrosis: what happens when the tooth nerve dies
Tooth pain can be alarming and disruptive, making it hard to enjoy even simple daily moments. One possible cause of lingering or severe tooth pain is pulp necrosis, a condition that occurs when the nerve inside your tooth dies. While "dead tooth" might sound dire, it’s a treatable condition if addressed promptly by a dental expert, such as an endodontist.
This blog post will explain what pulp necrosis is, its causes, symptoms and how it’s diagnosed. We'll also cover treatment options and share tips to help prevent it altogether.
What is pulp necrosis?
Pulp necrosis occurs when the pulp tissue inside a tooth becomes damaged or dies. The pulp is the soft tissue in the center of each tooth that contains nerves, connective tissue and blood vessels. It plays a vital role in keeping your teeth alive and healthy. When the pulp is injured or infected and cannot heal on its own, it may begin to die, leading to necrosis.
While pulp necrosis can seem overwhelming, understanding it is the first step toward ensuring your oral health remains intact. Fortunately, our team at West Fort Worth Endodontics offers effective solutions.
Causes of pulp necrosis
The primary causes of pulp necrosis are injury, infection or decay. Here's a closer look at some of the most common triggers:
Deep tooth decay: Untreated cavities can gradually eat through enamel and dentin, reaching the pulp and causing an infection that leads to necrosis.
Dental trauma: A sports injury, accident or any hard impact to the mouth can damage the pulp. Sometimes, the damage might not be immediately noticeable, but over time it can interrupt blood flow and cause the pulp to die.
Repeated dental procedures: Teeth that undergo multiple fillings, crowns or other procedures are at a higher risk of pulp damage, especially if the tooth structure becomes weakened.
Cracked or fractured teeth: Cracks or fractures may expose the inner layers of a tooth, allowing bacteria to penetrate the pulp and cause infection.
Severe gum disease (periodontitis): Advanced gum disease can lead to inflammation and infection around the roots of teeth, putting pressure on the pulp and cutting off its blood supply.

Symptoms of pulp necrosis
Pulp necrosis doesn’t always cause immediate pain, which is why it’s often overlooked. However, as the condition progresses, certain symptoms can indicate an issue:
Persistent tooth pain or sensitivity, especially when eating or drinking hot or cold foods
Tooth discoloration, such as a grayish or darker appearance
Swelling at the gum line near the affected tooth
A recurring or bad taste in your mouth, indicating bacterial infection
An abscess or pus-filled pocket at the base of the tooth
If you’re noticing these signs, it’s essential to consult your endodontist promptly. Early detection and treatment are key to avoiding complications.
How endodontists diagnose pulp necrosis
Diagnosis starts with a thorough examination by your dentist or endodontist. Here's what to expect during your visit:
Detailed discussion: Your endodontist will ask about your symptoms, dental history and any recent injuries you may have experienced.
Visual examination: The endodontist will look for signs such as tooth decay, fractures or discoloration during an oral inspection.
X-rays: X-rays allow endodontists to assess the internal structure of your tooth, check for abscesses and determine if the pulp has been damaged.
Pulp vitality testing: This test involves applying hot, cold, or electric stimuli to the affected tooth to evaluate whether the pulp responds. Lack of sensitivity often indicates necrosis.
Accurate diagnosis helps your dental provider recommend the most effective treatment for your condition.
Treatment options for pulp necrosis
Once pulp necrosis has been confirmed, treatment is necessary to stop the infection from spreading and to preserve your smile. The two most common treatment options are:
Root canal therapy
Root canal therapy is the most common treatment for a tooth with necrotic pulp. During the procedure:
The infected or dead pulp is removed.
The tooth’s canals are disinfected and sealed to prevent further bacterial growth.
The tooth is restored with a crown or filling for functionality and protection.
Root canal therapy is highly effective at saving your natural tooth and alleviating pain. For those in the Dallas/Fort Worth area of Texas, know that West Fort Worth Endodontics is ready to help.
Tooth extraction
If the tooth is too badly damaged to be saved, extraction may be necessary. Once removed, you can opt for a replacement, such as a dental implant or bridge, to restore function and appearance.
Your endodontist will recommend the best solution based on the extent of the damage and the health of the surrounding teeth.
Preventing pulp necrosis
Preventing pulp necrosis is simpler than dealing with its consequences. Here are some tips to maintain healthy teeth and gums:
Practice good oral hygiene: Brush your teeth twice a day with fluoride toothpaste and floss daily to prevent decay and gum disease.
Visit your dentist regularly: Routine check-ups and cleanings help catch issues before they become severe. A professional cleaning can remove plaque and tartar build-up that brushing or flossing can miss.
Wear a mouthguard: If you play contact sports, protect your teeth from trauma by wearing a custom-fitted mouthguard.
Address dental issues promptly: Don’t ignore persistent tooth pain, sensitivity, or gum issues. Early intervention can save your teeth from severe damage.
Avoid chewing hard objects: Chewing on ice, pens, or other hard items can crack or fracture your teeth, making them vulnerable to pulp exposure.
By following these tips, you can significantly reduce the risk of tooth injuries or infection.
