if the tooth is not visible to remove it means that its relatively deeply impacted and surgery would be technically difficult to perform. prices vary from place to place and depending on the competence of the operator can vary between 4k to 14k usually under local anesthesia, but on a case specific basis its best to show the xray and get examined by a competent maxillofacial surgeon to get the best service. always remember your body is priceless, dont bargain or negotiate with quality of surgical services for cheaper prices.
