Should I Go to the ER for an Exposed Tooth Nerve?

Published in Dental Emergencies 4 mins read

If you are experiencing excruciating tooth pain from an exposed nerve that you cannot bear for another second, or if there is prolonged and excessive bleeding in your mouth that you cannot control, then heading to the emergency room may be necessary. Otherwise, the primary course of action is to seek immediate dental attention from a qualified dentist.

Understanding an Exposed Tooth Nerve

An exposed tooth nerve occurs when the protective layers of your tooth – the enamel and dentin – are compromised, leaving the delicate pulp (which contains nerves and blood vessels) exposed to the oral environment. This exposure can be incredibly painful because the nerve is highly sensitive to temperature changes, pressure, and even air. Common causes include:

  • Deep cavities
  • Cracked or broken teeth
  • Trauma to the mouth
  • Severe gum recession

When an Exposed Nerve Becomes an ER Emergency

While an exposed tooth nerve always requires prompt dental care, it escalates to an emergency room situation based on the severity of your symptoms and potential complications. You should consider going to the ER if you experience:

  • Excruciating, Unbearable Pain: If the pain is so intense that you simply cannot tolerate it for another second, and it's severely impacting your ability to function (sleep, eat, speak), an ER can help manage the pain while you await definitive dental treatment.
  • Prolonged, Excessive Mouth Bleeding: If the exposure is due to trauma and results in significant, uncontrolled bleeding that you cannot stop with pressure, this warrants immediate emergency medical attention.
  • Signs of Spreading Infection (beyond the scope of the provided reference, but important general knowledge for ER visits): Although not directly from the provided reference for exposed nerves, accompanying symptoms like facial swelling that is rapidly worsening, difficulty breathing or swallowing, or a high fever alongside severe pain could indicate a serious infection spreading from the tooth, which is a medical emergency.

What to Do If It's Not an ER Emergency

For an exposed tooth nerve that causes severe pain but doesn't meet the ER criteria above, you still need urgent care. Here’s what to do:

  • Contact an Emergency Dentist: Call your dentist immediately or an emergency dental clinic. They can often see you the same day or provide guidance over the phone.
  • Manage Pain Temporarily:
    • Take over-the-counter pain relievers like ibuprofen or acetaminophen.
    • Avoid hot, cold, sweet, or acidic foods and drinks, as these can trigger intense pain.
    • Rinse your mouth gently with warm salt water to help keep the area clean.
    • You might gently apply a dental wax or sugar-free gum over the exposed area if possible, to temporarily shield the nerve from external stimuli, but this is not a permanent solution.
  • Maintain Good Oral Hygiene: Gently brush and floss around the area to prevent further irritation or infection.

When to Seek Immediate Care

The table below summarizes when to prioritize an ER visit versus an urgent dental appointment for an exposed tooth nerve:

Symptom Recommended Action
Excruciating, Unbearable Pain Emergency Room (ER) for pain management if you cannot wait for dental care.
Prolonged, Excessive Bleeding Emergency Room (ER) for immediate medical attention to control bleeding.
Moderate to Severe Pain (Bearable) Urgent Dental Appointment as soon as possible.
Sensitivity to Hot/Cold/Air Urgent Dental Appointment to prevent further damage and pain.
Visible Exposure without Extreme Pain Urgent Dental Appointment to prevent infection and further sensitivity.
Signs of Spreading Infection (Swelling, Fever) Emergency Room (ER) if severe and rapid, otherwise an urgent dental appointment if less critical.

Always prioritize professional dental consultation for an exposed tooth nerve, as untreated issues can lead to severe infections, tooth loss, or other serious health complications. For general information on maintaining oral health, consult resources like the American Dental Association.
