Root pain should be considered. Pain in the roots of the teeth may be caused by acute pulpitis, acute periapical inflammation and acute periodontitis. It is necessary to actively improve the examination to clarify the specific condition before treatment. In clinical practice, the main causes of root pain are oral diseases, such as root nerve damage, tooth decay, gingivitis, etc. Excessive consumption of irritating foods (too hard food, etc.) can also lead to root pain.
