What is tested?
A tooth’s response to a stimulus such as cold.
← All explanationsPulp sensibility / cold test
What does a tooth’s cold response tell us?
A pulp sensibility test checks whether and how a tooth responds to a stimulus, often cold. It offers information about nerve function inside the tooth. It does not directly measure blood flow and cannot alone prove that the pulp is healthy or dead.

A brief response is tested
Cold is applied to the tooth in a controlled way. Perception, strength and duration of the response matter, along with comparison with other teeth.
One test is not a diagnosis
No response can have several explanations, including a recent injury. A strong or lingering response is also only one part of the findings.
Interpret findings together
Symptoms, injury history, examination and X-rays when indicated complement the test. Together they help determine whether monitoring or treatment is appropriate.

What does the result mean?
A clue about nerve function, not a stand-alone diagnosis.
What complements the test?
Symptom history, comparison teeth, examination and imaging when needed.

Often confused
Sensibility or vitality?
Sensibility means a nerve response to stimulation. Vitality refers to living, perfused tissue. The terms are often interchanged but do not mean exactly the same thing.
Quick answers
Is a cold test the same as a vitality test?
It is often called that in everyday use. Strictly, it tests nerve sensibility. True vitality methods assess blood supply, which is not the same thing.
Does no response automatically mean the pulp is dead?
No. Results can be unclear after trauma or when the stimulus does not transmit normally. Comparison tests, follow-up and other findings help interpretation.
Can I test it myself with ice?
A home test does not replace standardised examination. Uncontrolled stimuli and lack of comparison can mislead. Have the cause of symptoms assessed instead.

For your consultation
A question to discuss with Dr. med. dent. Niusha Barahmand Pour:
How does my tooth’s response fit the other findings, and would a follow-up check help?
Symptoms, examination findings and personal wishes form the basis of individual treatment planning.
A tooth responds differently than before? Its cause can be assessed specifically.

- Sensibility test
- Testing the nerves’ response to a stimulus.
- Electric pulp test
- Another way of testing a nerve response using an electrical stimulus.
- Control tooth
- Another tooth tested for comparison as part of interpretation.
Know the difference
The cold test must be interpreted with history and clinical examination. One positive or negative result cannot establish a precise histological pulp diagnosis.
