01In brief
Tooth hurts with hot or cold: is it urgent?
Depends on the pain
Brief sensitivity to cold that goes away in a few seconds is common and usually not urgent. On the other hand, pain that lingers after something hot or cold, comes back on its own or wakes you up can signal an inflamed tooth nerve and should be seen quickly. Call the Go Dentiste clinic in Valleyfield at 514-533-3368; if the pain is intense, ask to be seen the same day, subject to availability.

- Book an appointmentSooner if the pain lingers, comes back on its own or wakes you up.

04At the Valleyfield clinic
How the dentist finds the cause
The dentist looks for the tooth and the cause: a cavity, a cracked filling, a root exposed by a receding gum, a cracked tooth or an inflamed nerve. The dentist does cold and tapping tests and takes an X-ray.
Depending on the case: a varnish or desensitizing treatment, a filling, gum treatment, or a root canal if the nerve is affected.

06FAQ
Frequently asked questions: pain with hot or cold
Why does my tooth hurt more with hot than with cold?
Lingering pain with heat can mean the tooth’s nerve is badly inflamed. Have it checked quickly.
Is toothpaste for sensitive teeth enough?
For mild sensitivity caused by an exposed root, it often helps after a few weeks of use. It does not treat a cavity, a crack or an inflamed nerve.
My tooth has been sensitive since a new filling: is that normal?
Mild sensitivity that eases over a few days or weeks can be normal. Pain that gets worse, lingers or happens when you bite should be reported.
Only one tooth is sensitive: why?
Sensitivity limited to one tooth points more to a cavity, a damaged filling or a crack. It should be examined.
