Cold sensitivity happens. One reason is a little recession of the gum which then makes the tooth hurt as cold hits it. This gum recession leads to irritation to the nerve of the tooth housed in the inner pulp layers of teeth can lead to cold sensitivity. The thinnest part of the enamel covers the tooth roots, so when gums recede exposing the roots, teeth are more likely to be sensitive to cold. There are gum protecting toothpastes like sensodyne. I use that for a few days and this gets better. When is the last time you went to the dentist?
