In most people, the third set of molars, generally called “wisdom teeth,” start coming in around age 17-25. However, the arrival of these teeth is often far from trouble-free. The extraction (removal) of one or more third molars is a relatively common procedure, performed on some 5 million patients every year. After a thorough examination and diagnostic tests, you may be told that you should have your wisdom teeth extracted. Here are some typical reasons why:
Whether it is aimed at preventing future problems or needed to alleviate a condition you already have, the extraction of wisdom teeth can be an effective treatment. But, as with all medical procedures, its benefits must be weighed against the small risk of complications, and should be discussed in detail.
Wisdom tooth extraction is usually an in-office procedure.
It's quite possible to have the treatment done with only a local anesthetic (numbing shot) to keep you from experiencing any pain; however, if multiple teeth are being extracted at one time (as is often the case), a general anesthetic or conscious sedation may be administered. The type of anesthesia that's best for you will be determined before the procedure.
Once you have been appropriately anesthetized, the gum tissue at the extraction site may need to be opened if the tooth is impacted. The tooth itself will then be gently removed.
When the extraction is complete, you may need to have the site sutured (stitched) to aid healing. After the procedure is over, you will rest for a short time before going home. .
Depending on what type of anesthesia you have had, you may need another person to drive.
The recovery period after wisdom tooth extraction generally lasts only a few days. During this time, you should rest when possible to encourage healing, and take any pain medication as prescribed. It's normal to experience some bleeding at the extraction site; this can be controlled by gently biting on gauze pads, changing them as needed, and resting with the head elevated on pillows rather than flat.
Holding an ice pack on the outside of your cheek for a few minutes at a time (for example, 5 minutes on / 5 minutes off) may help reduce swelling on the first day after the procedure. Starting on day 2, the warm moist heat of a washcloth placed on the cheek may make you more comfortable. Rinsing the mouth with warm salt water a few times a day can also help relieve discomfort.
You may want to eat soft foods for a few days after the extraction; likewise, be careful when brushing or putting anything in your mouth until your healing is complete. Be sure to follow the postoperative instructions you are given, as each situation is a little different; this will help you to be as comfortable as possible.
