It is charged by the piece.
If the wisdom teeth are inflamed, decayed, painful and dislocated, it is easy to cause dental caries of the front teeth. It is recommended that you delete them. There will be an alveolus after tooth extraction, and the tooth extraction wound will recover in about a month.
I can't give you an estimated price, and the charging standard is different in every place.
I suggest you go to a regular dental clinic for tooth extraction. Tooth extraction equipment needs professional disinfection, otherwise it is easy to be infected.
I hope it helps you.
