A sore tongue or lip after a dental filling is usually caused by accidentally biting the area while it was still numb from the local anesthetic. Mild irritation, tenderness, or a small ulcer often heals within a few days. Rinsing gently with warm salt water, eating soft foods, and avoiding spicy or acidic foods can help ease discomfort. If soreness worsens, lasts longer than a week, or is accompanied by swelling, fever, or persistent numbness, contact your dentist for an evaluation.
