How to stop my sensitive teeth from hurting

Sensitive teeth often improve when exposed dentine is protected and the cause, such as recession, wear, or decay, is treated.

Sensitivity occurs when open dentinal tubules transmit temperature, touch, or chemical changes toward the pulp. Receding gums, enamel wear, erosion, a cracked tooth, whitening, or decay can expose dentine.

Use a soft toothbrush with gentle pressure and a fluoride toothpaste made for sensitivity. Limit acidic drinks, avoid brushing immediately after acid exposure, and stop whitening until the cause is assessed.

Arrange dental care if sensitivity is confined to one tooth, is severe, persists, or occurs without a clear trigger. Swelling, spontaneous pain, or pain that lingers after cold can indicate pulp inflammation.

Ask whether dentine is exposed, whether there is recession, wear, decay, or a crack, and which fluoride treatment, restoration, or bite adjustment fits the cause.
