It is possible to replace a missing tooth using a dental implant, i.e. an artificial root. The tooth itself is built on top of the implant. The implant grows permanently into the bone and the crown feels like a real tooth.
The dentist always discusses different care options with the patient, but sometimes the tooth is so damages, full of cavities and in such a bad state that there is no choice by to extract it. Extraction of a wisdom tooth is the most common dental extraction procedure.
