IF IT HAPPENS WHEN YOU BRUSH,
could be a sign of tooth sensitivity and the cold water you’re brushing with is reaching the nerve of the tooth. If, however, it’s independent of brushing and the pain also involves your jaw, it might be a sign that you’re grinding your teeth at night. “People can grind or clench their teeth both day and night but it’s harder to control during sleep and this can result in jaw pain or soreness the next day,” says Dr Alice Yang. Speak to your dentist if you suspect it.
