If a tooth has been damaged or decayed and cannot be repaired using general dental techniques such as fillings, crowns, or root canals, then the tooth may have to be extracted or ‘pulled.’ Also, teeth may grow at incorrect angles and put pressure on other teeth or become infected. In these cases, the teeth may also need to be extracted. In all of these cases, the dentist will analyze your situation using diagnostic tools such as x-rays and dental exams. Often, if the tooth is visible, pulling the tooth can be a simple extraction. First the tooth is loosened by using various instruments, and it is then pulled. On the other hand, if the tooth has broken off at the gum line or has not come into the mouth, a more complex surgical procedure may be required.
