What should I do if my tooth hurts but has no cavity?

When teeth hurt despite no obvious cavities being present, several possible causes may be involved, including interproximal caries, pulpitis, pericoronitis of wisdom teeth, cracked tooth syndrome, and other dental conditions. These issues may arise due to tooth sensitivity, structural weaknesses in the tooth, dental trauma, or infectious factors. In such cases, it is recommended to seek prompt medical attention and visit the dental department of a hospital for a thorough examination to determine the exact cause of the pain. Treatment options may include root canal therapy, local irrigation and medication application, cyst curettage, tumor excision, etc., depending on the specific underlying condition. While awaiting medical care, you may try some temporary measures to relieve tooth pain, such as placing a cotton ball soaked in alcohol or liquor into the ear canal on the affected side, or applying a cotton ball with mentholated oil near the painful tooth. However, please note that these methods only provide temporary relief and cannot replace professional treatment.
