Local anesthesia ?: Many cavities can appear to be small clinically and radiologically, but in the reality they are deeper. Once the dentinal tubules with nerve endings are penetrated; the pain stimuli are perceived. The heat of the high speed is the potential irritant. The impact of psychological factor is also important. Ask the dentist to use profound local anesthesia next time.
