Pain in the tooth next to the extracted tooth may be caused by exposed gums or a lesion on the tooth next to it, among other things. Teeth are closely spaced, and when one tooth is removed, the gums of the next tooth may become exposed, which can cause the tooth to become temporarily sensitive and painful. After a tooth is extracted, pain in the tooth next to it may be due to a lesion on the tooth itself. When acute pulpitis is present in the tooth, the undesirable symptom of toothache can occur. It is recommended that patients pay attention to personal oral hygiene in their daily life, and try to avoid spicy and stimulating as well as harder foods that can cause damage to the teeth. After a toothache occurs next to the extracted tooth, it is recommended to go to the dental hospital for examination and diagnosis in a timely manner, and choose the appropriate treatment under the guidance of the doctor.
