If the growth position of the tooth is normal and the tooth is intact, the tooth is good to be extracted, and the tooth can be extracted within 5 minutes, and there will be no inflammation, pain or fever after the operation. The other type of teeth, such as blocked wisdom teeth or horizontal blocked wisdom teeth, and decayed carious teeth, are more difficult to extract. The wisdom teeth that are blocked or horizontally blocked need to be X-rayed to understand the specific situation of the tooth, and then the horizontal wisdom teeth may even need to be extracted by surgery. The carious teeth are not complete, so in order to prevent the residue of the root or the tooth, it is more necessary to extract the tooth with time and effort, and these teeth are not very easy to extract.
