Immediate relief for tooth sensitivity
To calm tooth sensitivity now, avoid the trigger, use a soft brush, and apply desensitizing toothpaste while arranging an examination.
The short answer
Immediate relief usually comes from avoiding hot, cold, sweet, or acidic triggers and using desensitizing fluoride toothpaste gently on the sensitive area.
Why does exposed dentine cause a short sharp response?
Tooth sensitivity is a short, sharp response when exposed dentine lets temperature, touch, or chemicals affect the pulp through tiny tubules. Receding gums, enamel wear, a crack, decay, or recent dental treatment can expose or irritate that pathway.
How should you care for teeth during sensitivity?
Rinse away acidic drinks with water, pause whitening products, and brush with a soft-bristled brush without scrubbing. A dentist may apply fluoride varnish, a desensitizing agent, a filling, or treatment for the pulp after identifying the cause.
When should ongoing tooth sensitivity be checked?
Book care when sensitivity persists, occurs in one tooth, follows an injury, or changes into lingering pain. Swelling, fever, pain on biting, or a broken tooth needs prompt assessment because sensitivity can accompany deeper inflammation.
Which causes can produce this pattern of tooth pain?
Ask whether the pain pattern fits exposed dentine, decay, a crack, gum recession, or pulp inflammation. Ask which toothpaste or in-office treatment is appropriate and whether an X-ray or bite test is needed.
Frequently asked questions
Should I put aspirin on the tooth?
Do not place aspirin on gum or tooth because it can irritate oral tissue; use an appropriate pain medicine only as directed on its label or by a clinician.
Why is one tooth suddenly sensitive?
A localized change may come from decay, a crack, a loose filling, gum recession, or pulp irritation and should be examined.
