How to stop tooth sensitivity

To reduce tooth sensitivity, use a soft brush and sensitivity toothpaste while arranging an examination for decay, cracks, erosion, or exposed roots.

Sensitivity is a brief sharp response when dentine or root surface is exposed to cold, touch, sweets, or air. Fluid movement in dentinal tubules stimulates the pulp nerves, but similar pain can also come from decay, a crack, or inflamed pulp.

Brush gently twice daily with fluoride toothpaste made for sensitivity, avoid aggressive horizontal scrubbing, and reduce repeated acidic drinks. Do not ignore sensitivity in one tooth, pain that lingers, or pain that occurs without a trigger.

Seek care when sensitivity is new and persistent, localized, worsening, or accompanied by a cavity, fracture, swelling, spontaneous pain, or lingering heat or cold pain. The dentist may test the pulp, examine the bite, and take an X-ray.

Ask which surface is exposed, whether there is decay or a crack, and whether fluoride treatment, a restoration, gum treatment, or root canal care is appropriate.
