Yes u cn use sensodyne toothpaste ... but take  an opinion from a dentist some tyms small cavities on the brushing surfaces can cause sensitivity filling those cavities might reduce ur symptoms .... if the problem persists and if it's very inconvenient, u cn go for more advanced treatments which cn be done only by a dentist. After brushing there vl be increased production of saliva and it represents good and healthy salivary glands so it's nt an actual problem to worry about
