That all depends on the type and severity of the problem identified. If during a dental checkup the dentist finds a cavity, a cracked tooth, or the patient needs a root canal, they would take care of it right away. If someone needs oral surgery or wants implants, the dentist may schedule a secondary appointment. Otherwise, if necessary, the dentist will refer them to a qualified oral surgeon. A dentist can take care of many problems during a standard dental checkup.
