Molar tooth pain may happen because of tooth decay, cavity, gum infection, food stuck between the teeth, wisdom tooth problems, cracked tooth, or inflammation around the tooth nerve. The pain may feel throbbing, sharp, or sensitive while chewing, drinking hot or cold liquids, or lying down. Swelling, bad taste in the mouth, or headache may also occur if infection is present. Pain-relieving medicines may help reduce tooth pain temporarily until proper dental treatment is done. Warm saltwater rinses, keeping the mouth clean, avoiding very hot, cold, or sugary foods, and gently removing trapped food particles may also help reduce irritation. Cold compresses outside the cheek may help if there is mild swelling. If the pain is due to infection or abscess, dental treatment and sometimes antibiotics may be needed after examination because medicines alone may not permanently solve the problem. Avoid placing aspirin directly on the gums or teeth because it may irritate and damage the tissue. Consult a dentist if swelling increases, fever appears, pus discharge occurs, pain becomes severe at night, or chewing becomes very difficult.
