A rotten wisdom tooth will not necessarily fall out on its own. When a wisdom tooth becomes severely decayed or infected, the structural integrity of the tooth is compromised, and it may become loose. However, even if the tooth becomes loose, it may not fall out naturally, especially if it remains partially or fully impacted beneath the gum line. Rotten wisdom teeth are typically best addressed through dental intervention. A dentist or oral surgeon may recommend extracting the rotten wisdom tooth to prevent the spread of infection and alleviate pain or discomfort. Dental extraction is a common and safe procedure that removes the compromised tooth to protect overall oral health.
