Many adults start experiencing sensitivity to cold, hot or sweet food and beverages. Scientific evidence shows that the cause of sensitive teeth is due to an increase in gum recession and toothbrush abrasion. This is because of incorrect brushing techniques.
Once the necks of the teeth are exposed, they become vulnerable to changes in temperature. Moreover, foods or beverages that are excessively acidic erode the tooth surface and cause dentine hypersensitivity. Regarding of the triggers or the frequency, you should let your dental care provider know immediately in order to ensure appropriate treatment.
