When a tooth is removed, the nerve that lived inside it comes out as well. Every tooth has a soft center called the pulp, which contains the nerve and blood vessels. When the entire tooth is lifted from the socket, this internal nerve is disconnected from the main nerve branch in your jaw and stays inside the tooth. This is why a tooth stops feeling heat, cold, or pain once it has been fully extracted by a professional.
What Happens to the Nerve During Extraction?
Many patients worry about what happens to the connection between the tooth and the jaw. During a visit to a dental clinic in Calgary, the dentist carefully loosens the tooth from the bone. The tiny nerve fibres that enter the bottom of the tooth root are very thin, almost like a piece of thread. As the tooth is pulled, these fibres snap cleanly at the entry point. Because the area is numbed, you do not feel this disconnection happening.
If you are feeling very nervous about the sensation of the tooth being moved, you might consider sedation dentistry near you. This option helps you feel sleepy or deeply relaxed so that you don’t notice the pressure or sounds of the procedure. It is a great choice for people who want to stay calm while the dentist ensures the tooth and its internal nerve are safely removed.
Can a Nerve Be Left Behind?
One common question people ask is, “Can a nerve be left behind after extraction?” The answer is generally no. The nerve that causes a toothache is located inside the “pulp chamber” of the tooth itself. Once the tooth is gone, that specific source of pain is gone too. However, the larger main nerves that run through your jawbone stay exactly where they are. These main nerves are what give feeling to your lips, chin, and tongue, and they are not touched during a standard extraction.
While extracting the tooth, dentists are very careful to protect these main jaw nerves. Our staff can see precisely where the roots of your teeth are located in relation to the larger nerves in your face through detailed X-rays. The careful planning of the surgery ensures that only the necessary parts are removed so that your jaw remains healthy.
What Does the Extraction Process Feel Like?
| Step | What Happens | What You Feel |
| Numbing | Medicine is applied to the gums | A tiny pinch, then nothing |
| Loosening | The tooth is gently moved | Pressure, but no sharp pain |
| Removal | The tooth and nerve come out | A sensation of “release.” |
| Aftercare | A gauze pad is placed on the site | Mild thumping as the numb feeling fades |
Why the Pain Finally Stops
The reason an extraction works so well for a bad toothache is that it removes the nerve that was sending “pain signals” to your brain. If a tooth is badly decayed or broken, the nerve inside gets irritated or infected. By taking the tooth out, the dentist removes the source of the infection and the nerve that was hurting. This allows the socket in your gums to heal and stay clean.
Healing After the Nerve is Gone
Once the tooth and its nerve are out, your body begins to fill the empty socket with a blood clot. This clot acts like a natural bandage. Over time, new bone and gum tissue will grow into that space. It is normal to feel some soreness in the area for a few days, but this is different from a toothache. This is just your gums healing from the visit to a dental clinic near you. As long as you follow the cleaning instructions, the area will heal quickly and comfortably.

Frequently Asked Questions
Will I lose feeling in my face if the nerve is pulled?
No. The nerve inside the tooth is only for that specific tooth. The nerves that control your face and sense of touch in your skin are much deeper and are not removed during the process.
Why does it still feel like the tooth is there right after it’s pulled?
This is very common and is often called a “phantom” sensation. Because the area is numb and swollen, your brain might still think the tooth is there for a few hours. This feeling goes away as the numbness wears off.
Can the nerve grow back after the tooth is gone?
No, the nerve for that specific tooth cannot grow back once the tooth has been removed. The space will eventually fill with bone and gum tissue.
Is it normal to have a “zing” of pain a few days later?
Sometimes the surrounding nerves in the gums get a little sensitive during the healing process. This usually stops within a few days as the blood clot protects the area.
