In dentistry, an extraction is the removal of a tooth. There are several reasons why we may recommend an extraction including:
Sometimes your dentist will recommend that you have your wisdom teeth, or 3rd molars, removed to prevent future problems such as; bone loss, root resorption (which is the breakdown or destruction of the tooth’s root structure) and caries formation (tooth decay or cavities) of the 2nd molars, around the wisdom teeth. This will be recommended particularly if your wisdom teeth are not functional or you cannot keep them clean (they are hard to reach!).
Your dentist will begin by numbing the area where the tooth is being extracted, to minimize any discomfort. Then, he/she will advise you of a regimen to follow during healing. You can expect a small amount of bleeding. A blood clot will fill in the bone where the tooth root was.
Tooth extractions, along with modern dental procedures and follow up care will result in better overall health and comfort.
