What becomes inflamed in pulpitis?

Pulpitis means inflammation of the pulp inside a tooth. Causes can include deep decay or an injury. Pain intensity alone cannot determine which treatment is needed.

For dental trainees & teams

01 / 03

Inflammation inside the tooth

The pulp contains nerves, blood vessels and connective tissue. When it becomes irritated and inflamed, for example due to deep decay or an injury, this is called pulpitis.

02 / 03

Symptoms offer clues, not certainty

Cold or heat may trigger pain; pain may also occur spontaneously. Its course, the examination and tests are assessed together. A response to one stimulus is not enough.

03 / 03

The findings determine treatment

Depending on the condition, treatment to preserve pulp tissue or root canal treatment may be considered. Persistent or spontaneous toothache should be assessed promptly.

Often confused

Pulpitis or pulp necrosis?

Pulpitis is inflammation of pulp tissue. Necrosis means tissue has died. They are not the same and require clinical assessment.

Quick answers

Is every tooth sensitive to cold inflamed?

No. Exposed dentine and other changes can also cause sensitivity. The cause needs examination.

Does pulpitis always mean root canal treatment?

No. Depending on the findings, measures to preserve pulp tissue may be possible. An examination establishes the options.

How is pulpitis diagnosed?

Symptoms and history are considered alongside clinical tests and, where appropriate, X-ray findings. A photograph or a single cold test is not enough for a reliable assessment.

At the practice

For your consultation

A question to discuss with Dr. med. dent. Niusha Barahmand Pour:

Which findings point to the cause of my pain, and can pulp tissue be preserved?

The practice profile lists continuing education in endodontics; the individual's starting situation forms the basis of treatment planning.

Persistent or spontaneous toothache should be assessed by a dentist promptly.

Learning for dental trainees & teamsUnderstand clinical terms and build your knowledge

Build on the simple explanation with clinical terms, key distinctions and a knowledge question.

Sensibility testing: Testing the response to a stimulus; it does not directly measure blood flow in the pulp.
Vital pulp therapy: Treatment aimed at preserving living pulp tissue and its function.
Pulp necrosis: Death of pulp tissue; different from inflammation of living tissue.

Know the difference

Pain intensity or a single test proves neither the extent of pulp damage nor whether it can be preserved. Several findings are assessed together.

Knowledge questionWhat does a cold test on a tooth directly show?

This question supports learning. It does not assess personal symptoms.

Whether all areas of the pulp have an adequate blood supply.
Whether root canal treatment is needed, regardless of other findings.
How the tooth responds to the cold stimulus.

Show answer and explanation

How the tooth responds to the cold stimulus.

Sensibility testing records a response. It forms part of the examination, but does not determine pulp vitality or treatment on its own.
