Dental question about observed-topic:tooth-sensitivity

Tooth sensitivity is a brief sharp response when exposed dentin lets cold, heat, touch, sweets, or air stimulate the pulp.

Recession, erosion, abrasion, gum disease, decay, cracks, worn fillings, and whitening can expose dentin or irritate the pulp.

Brush gently with a soft brush and fluoride toothpaste, limit frequent acids, and arrange care if pain lingers, starts spontaneously, or affects one tooth.

Seek urgent care for facial swelling, fever, severe pain, or difficulty swallowing or breathing.

Ask what is causing the finding, which examination or tests are needed, and which treatment addresses the cause.
