This is where toothache comes from.
Updated: Nov 3, 2025
Teeth have nerves. That's why they can feel hot and cold, sensitivity and pain. The nerve inside a tooth is called dental pulp, which contains large nerve trunks and blood vessels. Alos this is where toothache comes from.
When decays or cracks involve nerves, severe toothache may happen, especially at night time, which often ends up with a dental emergency. If the tooth can be saved, your dentist will recommend root canal treatment. The first step of root canal treatment involves removal of nerves (pulp extirpation), hence gets rid of the dental pain. The picture above shows the nerve was removed by a barbed broach. Then the root canal system will be cleaned, prepared and filled with gutta-percha.
To avoid this endodontic emergency, make sure to maintain a good oral hygiene with good brushing and flossing and visit your dentist regularly.
It was really interesting reading about how dental pulp inflammation drives that intense, late-night throbbing pain, especially the detail on using a barbed broach during pulp extirpation to relieve it quickly. As an academic tutor balancing late study hours, seeing practical dental procedures mapped out reminds me of helping students with their healthcare assignments using New Assignment Help and their Case Study Writing Service Australia to break down complex medical workflows into digestible research notes. It definitely highlights how crucial routine check-ups are to catch minor decay before it turns into a painful endodontic emergency. Thanks for sharing such a clear breakdown of the root canal process!
