Teeth sensitive to cold remedy
Desensitising toothpaste may help cold-sensitive teeth, but persistent or localised pain needs assessment for decay, cracks, or pulp disease.
The short answer
Cold sensitivity is often reduced by removing the trigger and using a desensitising toothpaste, but persistent or one-tooth pain needs an examination for decay, cracks, or pulp inflammation.
Why can cold reach the sensitive inner tooth surface?
Cold can stimulate exposed dentine tubules when gum recession, enamel wear, erosion, abrasion, decay, a crack, or recent dental treatment exposes the inner tooth surface. A brief sensation that stops when the cold is removed differs from pain that lingers or starts spontaneously.
How can you reduce cold sensitivity at home?
Use a soft brush with gentle pressure and a toothpaste formulated for dentine sensitivity. Avoid repeatedly testing the tooth with ice, reduce acidic drinks, and do not place aspirin or concentrated chemicals on the gum.
When should cold sensitivity be examined by a dentist?
Book an examination if sensitivity is localised, worsening, lingering after cold, triggered by biting, or accompanied by swelling, a bad taste, or spontaneous pain. Urgent care is appropriate for facial swelling or difficulty breathing or swallowing.
What is causing the cold sensitivity in your tooth?
Ask whether the cause is exposed dentine, decay, a crack, gum recession, or pulp disease, and whether fluoride treatment, a restoration, bite adjustment, or root canal treatment is indicated.
