Teeth are extracted for a variety of reasons:
Decay has reached deep into the tooth
Infection has destroyed the tooth or surrounding bone
There is not enough room for all the teeth in your mouth
Many dentists recommend extracting impacted teeth that are only partially erupted. Bacteria can enter around a partially erupted tooth and cause an infection. Removing a tooth that is impacted can often prevent infection, damage to adjacent teeth and bone, and save pain in the years to come.
Before a tooth is removed, your dentist will thoroughly review your medical and dental history and take the appropriate X-rays. X-rays reveal the length, shape, and position of the tooth and surrounding bone. Before removal, the area around your tooth will be anesthetized. Dentists use a local anesthetic to numb the area of the mouth where the extraction will take place. For a simple extraction, once the area is anesthetized, the tooth is loosened with the help of a tool called an elevator, then extracted with dental forceps. Your dentist may also want to smooth and recontour the underlying bone. When he or she is finished, they may choose to close the area with a stitch.
It is critical to keep the area clean and prevent infection immediately following the removal of a tooth. Your dentist will ask you to bite down gently on a piece of dry, sterile gauze, which you must keep in place for up to 30 to 45 minutes to limit bleeding while clotting takes place. For the next 24 hours, you shouldn't smoke, rinse your mouth vigorously, or clean the teeth next to the extraction site. A certain amount of pain and discomfort is to be expected following an extraction. In some cases, your dentist will recommend a pain killer or prescribe one for you. It may help to apply an ice pack to the face for 15 minutes at a time. You may also want to limit strenuous activity, as well as avoid hot liquids and not drink through a straw. Under normal circumstances, discomfort should lessen within three days to two weeks. If you have prolonged or severe pain, swelling, bleeding or fever, call your dentist at once.
