A short, sharp pain from cold water, hot drinks, sweet foods or brushing may be tooth sensitivity. Sensitivity is a symptom rather than a diagnosis and can have several causes.
This content is general information, not a personal diagnosis or treatment recommendation. A dental examination is needed for individual symptoms.
Pain that starts without a trigger, wakes you at night, lingers or occurs with swelling should not be treated as simple sensitivity and needs prompt assessment.
Common causes
Worn enamel, exposed roots from gum recession, decay, a cracked tooth, worn fillings, gum disease and recent whitening can all cause sensitivity.
Daily care
A fluoride toothpaste formulated for sensitivity may help some people. Use a soft-bristled brush, avoid aggressive horizontal brushing and limit frequent acidic drinks.
What will a dentist assess?
An examination can check for decay, cracks, filling margins, bite pressure, gum levels and enamel loss. Treatment depends on the cause and may include fluoride, bonding, a filling, gum treatment or other care.
