It is not necessary to have an implant after the extraction of a tooth. Since wisdom teeth are located in the last part of the tooth row, it will not affect the teeth especially after it is removed. For example, a removable denture can be used for simple restorations, as long as the patient wears it every day. In addition, for fixed restorations, fixed bridges can be used to repair the gap, but they have the disadvantage that the teeth on both sides of the gap need to be ground down accordingly.
