What is a pulp stone?
A pulp stone is a calcified structure within the dental pulp, the tissue containing nerves and blood vessels. It may be found incidentally. When root-canal treatment is needed, larger calcifications can make access to the canals more difficult.

Inside the tooth
The pulp occupies the pulp chamber and root canals. A pulp stone is a local calcification in this region, not a deposit on the outer surface.
A finding is not automatically a cause of pain
Seeing a pulp stone does not prove that it causes symptoms. Symptoms and other findings must be assessed together.
Consider it during root-canal treatment
Calcifications can obstruct access to canal openings or instrumentation. Whether and how they need to be managed depends on the planned treatment.

When can it matter?
When assessing the finding or planning necessary root-canal treatment.
Does it automatically need treatment?
No. The overall tooth findings guide the decision.

Often confused
Pulp stone or narrowed canal?
A pulp stone is a localised calcification. Narrowing or obliteration of the pulp space describes broader reduction of the space; the terms are not interchangeable.
Quick answers
Is a pulp stone dental calculus?
No. Calculus forms on tooth surfaces. A pulp stone lies inside the tooth in the pulp region.
Must every pulp stone be removed?
No. This finding alone does not justify root-canal treatment. The tooth’s condition, symptoms and any necessary treatment determine management.
Does it diagnose another disease?
A pulp stone alone cannot diagnose a general medical condition. Such conclusions require separate medical assessment.
At the practice
For the appointment
You can bring this question to your appointment:
Is this an incidental finding, or does it affect treatment that is actually needed?
An imaging finding needs to be considered alongside symptoms and an examination.

- Pulp
- Soft tissue containing nerves and blood vessels inside a tooth.
- Pulp chamber

A pulp stone is a localised calcification. Narrowing or obliteration of the pulp space describes broader reduction of the space; the terms are not interchangeable.
