If you don't get a tooth extraction when recommended by your dentist, several potential consequences could arise depending on the specific reason for the recommendation:

Infection: If the tooth is severely decayed or infected, delaying extraction can lead to the spread of infection. This can cause abscesses, which are painful collections of pus, and potentially more serious systemic infections that can affect overall health.

Pain: An unresolved issue with a tooth, such as decay, infection, or impaction, can cause ongoing or worsening pain. This discomfort can interfere with daily activities, eating, and even sleeping.

Damage to Surrounding Teeth: An infected or problematic tooth can affect neighboring teeth. For example, an impacted wisdom tooth can push against adjacent teeth, leading to misalignment, decay, or damage to those teeth.
