There is living tissue inside a tooth
The pulp is protected inside the tooth. It includes nerves, blood vessels and connective tissue. “Tooth nerve” is a simplified everyday term for it.
From the crown into the root
Pulp tissue lies in the pulp chamber and extends into the root canals. Its roles include nourishment, sensation and tooth development.
Symptoms need an examination
Deep decay or injury can damage the pulp. The treatment needed depends on the findings. Not every response to cold means the pulp is seriously diseased.

Pulp or dentine?
The pulp is the soft tissue inside. Dentine is the hard layer around it. These terms describe different tissues.
Quick answers
Is the pulp just a single nerve?
No. It is a combination of tissues containing nerves, blood vessels and connective tissue. Blood supply is just as important as sensation.
Does toothache automatically mean root canal treatment?
No. Toothache can have different causes. An examination and, if necessary, further tests establish whether and how the inside of the tooth needs treatment.
Can a tooth remain after root canal treatment?
Yes. A mature tooth can survive without pulp tissue. It needs appropriate treatment, restoration and checks; keeping it cannot be guaranteed.
