Orthodontic expenses mainly include operation expenses, material expenses and instrument expenses. The specific costs will vary due to factors such as correction methods, hospital grades, and regional differences.

Generally speaking, the cost of traditional metal orthotics is relatively low, generally between 10000-30000 yuan. The cost of invisible orthotics is relatively high, generally between 20,000 and 50,000 yuan.

As for the cost of tooth extraction, generally speaking, tooth extraction needs to be charged separately. However, if the patient is young, he only needs tooth extraction for correction, and the cost of tooth extraction is usually not high, and may not even need to pay extra.

The specific cost also needs to be evaluated according to the specific situation of patients and the charging standards in the region. If in doubt, it is recommended to consult a professional dentist.
