The most common reasons for tooth extractions include:

• Severe tooth decay or infection may make it impossible or too costly to repair a tooth
• Advanced gum disease may required a tooth to be pulled so it doesn’t affect the supporting tissues and bone structures of your mouth
• A tooth may be extracted if it is blocking other teeth from coming in
• During orthodontic work, teeth may need to be extracted to create room for the teeth that are being moved into place
• Wisdom teeth are often extracted either before or after they come in

What to expect.
Your dentist will first administer anesthetic to numb the area and reduce discomfort. During the extraction, you will feel the pressure of the tooth being removed, but will not feel any pain. Typically, the dentist is able to remove your tooth within a matter of minutes.

Immediately after the tooth extraction, a small amount of bleeding is normal and patch of gauze will be placed in the affected area. The area may bleed minimally for the next 24 hours or so and taper off after that. Follow your dentist's instructions on how often to change the gauze, and what other post-procedure steps to follow.

Avoid anything that might prevent normal healing. It is usually best not to smoke or rinse your mouth vigorously, or drink through a straw for 24 hours. These activities could dislodge the clot and delay healing.

For the first few days, if you must rinse, rinse your mouth gently afterward, for pain or swelling, apply a cold cloth or an ice bag. Ask your dentist about pain medication. You can brush and floss the other teeth as usual. But don't clean the teeth next to the tooth socket.
