A broken wisdom tooth with a hole is caries of the wisdom tooth, which is an indication for wisdom tooth removal, so a broken wisdom tooth with a hole can be removed clinically after local anesthesia. Because the treatment of wisdom tooth caries is more complicated, the instrument is more difficult to reach, and the wisdom tooth is not very useful for chewing, it is likely to be difficult to treat after caries, and untreated will cause further other problems, so the wisdom tooth is removed as soon as possible after a hole is broken, which is also a common indication for wisdom tooth extraction. Therefore, if a wisdom tooth has a cavity, it does not need to be filled like other teeth or may need root canal treatment, but can be extracted directly.
