A clinical reason belongs to the assessed tooth
An explanation about a wisdom tooth can concern an assessed dental finding and its management. History, symptoms, examination and diagnostic assessment contribute different information. Having no pain does not by itself establish that a tooth is disease-free.
An impacted wisdom tooth has not fully come through because its path is physically blocked, for example by the tooth in front. The Cochrane review discussed here concerns impacted wisdom teeth without symptoms or evidence of disease, rather than every wisdom-tooth situation. Whether a tooth is impacted and belongs to that group requires individual clinical assessment.

A prevention claim asks a different question
The retrieved 2020 Cochrane review, searched through May 2019, does not establish that removing those teeth prevents later crowding. Its comparative evidence was uncertain. AAOMS's broader 2024 clinical statement favors surgical management of impacted third molars while describing selected monitoring circumstances. Those sources have different scopes; the evidence lesson explains both.

A current fit problem has its own response
A retainer that no longer fully fits, causes significant pain or looks damaged should not be forced into place. Contact the orthodontic team for assessment rather than reshaping it yourself. A simultaneous wisdom-tooth question does not identify why the fit changed.
The plan-and-retainer chapter distinguishes that situation from a mildly snug appliance that fully seats, completes Riley's example and keeps individual wear directions connected to the treating team.
