Immediate relief for sensitive teeth
For immediate sensitive-tooth relief, avoid the trigger, brush gently with fluoride toothpaste, and arrange an examination if it persists.
The short answer
Move away from the cold, hot, sweet, or acidic trigger, rinse with water, and brush gently with fluoride toothpaste. A desensitising toothpaste may reduce dentine sensitivity with continued use, but sudden or localised pain needs examination.
What is the direct answer?
What does this question mean?
Sensitivity occurs when exposed dentine allows fluid movement in microscopic tubules toward the pulp nerves. Recession, enamel wear, erosion, a cavity, a crack, or recent dental treatment can expose or irritate that pathway.
What can you do next?
Avoid whitening products and acidic drinks while the pain is active, use a soft brush, and do not scrub the necks of the teeth. A dentist may apply fluoride varnish or a dentine sealant, repair decay or a crack, or assess the pulp if pain lingers after the trigger.
When should you seek dental care?
Seek urgent care for spontaneous pain, pain that lingers, swelling, fever, a broken tooth, or pain that prevents sleep. Sensitivity that returns in one tooth should be checked even when it settles temporarily.
What should you ask the dentist?
Is the pain from exposed dentine, decay, a crack, the gum, or the pulp, and would fluoride, bonding, a filling, or root-canal assessment address the cause?
