Stop tooth sensitivity immediately
To calm tooth sensitivity, remove the trigger, use fluoride toothpaste, and arrange an examination to find exposed dentine or decay.
The short answer
To calm tooth sensitivity, remove the trigger, use fluoride toothpaste, and arrange an examination to find exposed dentine or decay. Do not place aspirin on the tooth or scrub the sensitive area.

What causes the short sharp pain of tooth sensitivity?
Sensitivity is a short, sharp response when hot, cold, sweet, acidic, or tactile stimuli reach dentine and activate nerves through dentinal tubules. Receding gums, enamel wear, cracks, decay, and recent dental treatment can expose or irritate that pathway.
What can you do now to reduce a sensitive tooth’s reaction?
Avoid the provoking food or drink, brush gently with a soft brush, and use a desensitizing fluoride toothpaste without rinsing heavily afterward. A dentist may apply fluoride varnish, seal exposed root surfaces, repair decay, or treat a cracked tooth.
When does tooth sensitivity require prompt dental care?
Seek care promptly when pain lingers, occurs without a trigger, is concentrated in one tooth, or comes with swelling, fever, or pain on biting. These features can indicate pulp inflammation, infection, decay, or a fracture rather than simple sensitivity.
What should you ask about testing the sensitive tooth?
Ask which surface is sensitive, whether the pulp responds normally, and whether bite testing or an X-ray is needed. Ask which treatment protects the exposed dentine and how long to try it before review.
Frequently asked questions
Can sensitivity stop on its own?
Temporary irritation may settle, but recurring or worsening pain needs assessment to exclude decay, cracks, or pulp disease.
Does sensitive toothpaste work instantly?
It may require repeated use because its ingredients reduce dentine fluid movement or block tubules over time.
