Mild tooth sensitivity after a filling is common, especially when you eat or drink something hot, cold, sweet, or sour. It may also occur when biting down or brushing near the treated tooth. This sensitivity usually happens because the dental filling procedure can temporarily irritate the tooth’s inner nerve. In many cases, the discomfort gradually improves within a few days or weeks.
However, severe, throbbing, or persistent tooth pain after a filling should not be ignored. Pain when biting may indicate that the filling is slightly high and needs adjustment. Sensitivity that worsens over time, pain that continues without any trigger, or discomfort that keeps you awake at night may suggest deeper decay, nerve inflammation, or the need for root canal treatment.
Until your tooth settles, avoid very hot, cold, and sugary foods, and brush gently with a soft toothbrush. Do not delay a dental check-up if symptoms persist, swelling develops, or you experience intense pain.
