Hello, whether tooth extraction is necessary for irregular teeth can be divided into two situations: the first situation can be decided by maxillofacial surgeons, and the other situation needs to be decided by orthodontists:

1, the maxillofacial surgeon can decide this situation, for example, there is only one premolar, and the upper four or five teeth are outside the dental arch, which may be inclined to the labial side or the palatal side. In this case, only one tooth is outside the arch, and the other teeth are still very neat. If this situation will cause local food impaction, it is recommended to extract teeth outside the dental arch;

2. If other dentition is crowded or uneven, it is recommended to let a regular orthodontist make a diagnosis and analysis. If the tooth needs to be extracted according to the treatment analysis, then pull out the tooth and ask the orthodontist to correct it for you. If the tooth extraction is not required according to the treatment plan, it should be treated slowly according to the treatment plan of the orthodontist. Maybe the teeth will be neat then, but there is no need to pull out the teeth.
