Per the "Important Information for the Class of 2027" document on the PTR website -
"USNA has an exceptional Dental Department that will provide all general and specialty dental care required during your four
years at the Academy. It is strongly suggested however, that each prospective Midshipman have a complete dental examination
performed by his/her family dentist prior to reporting, in order to have any acute dental conditions addressed prior to reporting.
Examples of acute dental conditions include any cavities or tooth decay that require restoration and extraction of any wisdom teeth
that are indicated for extraction. Candidates to U.S. Service Academies that have been advised by their dental provider to have their
wisdom teeth removed, would be wise to follow that advice. Ideally, it should be done to allow 8 weeks for healing and to recover
from any potential complications a candidate may experience. Prospective Midshipmen who arrive on I-Day with symptoms from
their wisdom teeth or with complications from wisdom teeth extractions “may” be denied admission."
