With this question, we consulted experts from Putian Stomatological Hospital. The expert told us that many people will be puzzled about whether tooth extraction is needed in dental plastic surgery, because tooth extraction is a commonly used dental treatment technique after all, and it is easy to cause local tissue damage, causing bleeding, swelling, pain, blood pressure, temperature and pulse fluctuations, so it must be treated with caution. Because of crowded dentition and prominent lips in China, there are many tooth extraction corrections. However, patients and parents don't have to be overly nervous about this, but tooth extraction correction is a relatively complicated correction after all. Doctors should carefully analyze all the clinical data of patients before they can determine a strict and reasonable correction plan. Others, although the teeth are not too crowded and protruding, have poor occlusion of the posterior teeth and low chewing efficiency. Moreover, it may cause damage to the temporomandibular joint in front of the ear, and it also needs tooth extraction correction. When the dentition is crowded, the teeth are irregularly arranged, such as the most common "tiger teeth", and the lower incisors are seriously crowded, so one tooth needs to be pulled out to provide a gap. Some people's teeth are protruding badly, and their mouths and lips are protruding, which is what people often say as "buck teeth". It is necessary to extract teeth and correct them, and press the front teeth in to see their mouths and lips.
