How Does a Dentist Kill a Nerve in Your Tooth?

Dental pain is no laughing matter. When a toothache strikes, it can be hard to focus on anything else. One common solution is to remove the nerve causing the pain. But how exactly does a dentist kill a nerve in your tooth? In this article, we’ll explore the process step by step.

Step 1: Numb the Area

Before any dental procedure, it’s important to ensure that the patient is comfortable and pain-free. To accomplish this, the dentist will use a local anesthetic to numb the area around the tooth. This will prevent the patient from feeling any pain during the procedure.

Step 2: Create Access to the Nerve

Once the area is numb, the dentist will create a small hole in the top of the tooth. This hole is called an access point and is necessary for the dentist to reach the nerve. The access point is typically created using a dental drill.

Step 3: Remove the Nerve

With the access point created, the dentist will use a set of small instruments to remove the nerve from the tooth. This is done by carefully inserting the instruments into the hole and scraping away the nerve tissue. It’s important to remove all of the nerve tissue to ensure that no pain signals can be sent to the brain.

Step 4: Clean and Fill the Tooth

Once the nerve has been removed, the dentist will clean out the inside of the tooth to ensure that no bacteria remain. After the cleaning, the tooth will be filled with a special material to seal the access point and prevent any future infections.

Step 5: Add a Crown (Optional)

In some cases, the tooth may be weakened by the removal of the nerve. To prevent further damage, the dentist may recommend adding a dental crown to strengthen the tooth. A dental crown is a cap that fits over the top of the tooth and provides additional support.


Now you know how a dentist kills a nerve in your tooth. Although the procedure may sound intimidating, it’s a routine process that can be completed quickly and painlessly. If you’re experiencing dental pain, don’t hesitate to contact your dentist to schedule an appointment. Remember, the sooner you seek treatment, the sooner you can be pain-free.
