Tooth sensitivity
A short, sharp pain with cold, heat, sweetness or touch, when the dentine is exposed.
What it is
Tooth sensitivity happens when the dentine, the layer under the enamel connected to the nerve, is left unprotected. Something cold, hot, sweet or acidic reaches the nerve and causes a short pain that stops as soon as the trigger is gone.
Why it happens
From gum recession, from enamel worn by hard brushing or grinding, from acidic food and drinks, after a clean or whitening, or from decay or a crack.
What can be done
A toothpaste for sensitive teeth, a soft brush and gentle brushing help most of the time. If the pain lasts long after the trigger or comes on its own, it isn't simple sensitivity any more: it's worth a check-up, because it may be decay or an inflamed nerve.
