Definite proof of a crack?
No. One test is insufficient.

What can a test during biting show?
A dental bite test checks whether controlled loading of a tooth or an individual cusp triggers symptoms. It can help narrow down the source of intermittent biting pain. A painful response alone does not prove a crack or determine treatment.

Narrow down the load
During examination, a tooth or an individual cusp may be loaded in a controlled way. This checks whether the reported symptoms can be reproduced at a specific site.
Biting and releasing
A cracked tooth may hurt when biting or as the load is released. Not every crack causes this pain, and not every biting pain means that a tooth is cracked.
Combine the findings
The bite test is considered alongside the history, tooth examination and other appropriate tests. The full picture helps assess the cause, extent and possible treatment.

Often confused
Bite test or cold test?
A bite test assesses the response to mechanical loading. A cold test checks the response to a temperature stimulus and gives information about pulp nerve function. Both provide partial information and do not replace a complete examination.
Quick answers
Does a positive bite test prove a tooth is cracked?
No. It is a finding that needs to fit the symptoms and the rest of the examination. A bite test alone does not establish how far a possible crack extends or the condition of the pulp.
Why might it hurt only when I release the bite?
Parts of a cracked tooth may move slightly under load and irritate the tissue inside the tooth. Pain on release is possible but is not proof of a crack on its own.
What other examinations may help?
Depending on the findings, pulp sensibility testing, examination around the gum margin, magnification, transillumination and justified radiographs may contribute. An early crack may not be visible on a radiograph.
Should I bite something hard at home to test it?
No. Do not deliberately provoke pain by biting hard objects forcefully. Note when the pain occurs and have the tooth assessed instead. A painless self-test could also create false reassurance.
At the practice
For the appointment
You can bring this question to your appointment:
Does the pain occur when biting, releasing the bite or also in response to cold?
Recurring biting pain can be assessed in a dental examination.

- Cusp
- A raised part of the chewing surface of a back tooth.
- Transillumination
- Passing light through a tooth; this can provide additional information when investigating some cracks.
- Pulp
- Tissue inside a tooth containing nerves, blood vessels and other cells.
Make the distinction
A bite test assesses the response to mechanical loading. A cold test checks the response to a temperature stimulus and gives information about pulp nerve function. Both provide partial information and do not replace a complete examination.
