5 Signs Your Tooth is Dead and What To Do About It

When a tooth becomes non-vital or “dead,” it can lead to serious dental problems if left untreated. Recognizing the signs of a dead tooth is crucial for timely intervention and proper dental care. In this article, we will explore five common signs that indicate a tooth is dead and discuss the appropriate steps to take to address the situation.

5 Signs Your Tooth Is Dead

  1. Discoloration: Discoloration is one of the primary signs of a dead tooth. The affected tooth may turn gray, yellow, or even black over time. This change occurs because the blood supply to the tooth has been compromised. If you notice abnormal tooth discoloration, it is essential to consult with a dentist to evaluate the tooth’s vitality and determine the appropriate treatment.
  2. Persistent or Severe Pain: A dead tooth may initially cause severe pain due to an underlying infection or decay that has reached the tooth’s pulp. However, as the tooth loses its vitality, the pain may subside. If you experience persistent or recurring pain in a specific tooth, it could be an indication of a dead tooth. Seeking dental care promptly is crucial to prevent further complications.
  3. Sensitivity to Heat or Cold: When a tooth is dead, it may lose its ability to sense temperature changes. Therefore, you may notice increased sensitivity or discomfort when consuming hot or cold foods and beverages. If you consistently experience heightened sensitivity in a specific tooth, it could be an indication of a non-vital tooth. Consulting a dentist is essential to determine the appropriate treatment.
  4. Swelling and Abscess Formation: A dead tooth can become a breeding ground for bacteria, leading to an infection in the surrounding tissues. This infection may cause swelling, tenderness, and the formation of a dental abscess. If you notice swelling or a pimple-like bump near the affected tooth, it is crucial to seek immediate dental attention to prevent the infection from spreading and causing further damage.
  5. Changes in Gum Appearance: A dead tooth can also impact the appearance of the surrounding gums. You may notice redness, inflammation, or even gum recession around the affected tooth. Changes in gum appearance can be a result of infection or inflammation caused by the non-vital tooth. Seeking professional dental care is vital to address the underlying cause and preserve gum health.

What To Do About a Dead Tooth:

If you suspect you have a dead tooth, it is important to schedule an appointment with a dentist as soon as possible. The dentist will conduct a thorough examination, which may include X-rays, to confirm the tooth’s vitality. Treatment options for a dead tooth can vary depending on the extent of damage and the patient’s specific circumstances. They may include root canal therapy, extraction, or other appropriate dental procedures.


Recognizing the signs of a dead tooth is crucial for timely intervention and proper dental care. If you experience tooth discoloration, persistent pain, sensitivity to temperature changes, swelling, or changes in gum appearance, it is important to consult with a dentist promptly. Early diagnosis and appropriate treatment can help preserve oral health and prevent further complications associated with a dead tooth.
