There are times when it is necessary to remove a tooth. Sometimes a baby tooth has misshapen or long roots that prevent it from falling out as it should, and the tooth must be removed to make way for the permanent tooth to erupt. At other times, a tooth may have so much decay that it puts the surrounding teeth at risk of decay, so your doctor may recommend removal and replacement with a bridge or implant. Infection, orthodontic correction, or problems with a wisdom tooth can also require removal of a tooth.
The root of each tooth is encased within your jawbone in a "tooth socket," and your tooth is held in that socket by a ligament. In order to extract a tooth, your dentist must expand the socket and separate the tooth from the ligament holding it in place. While this procedure is typically very quick, it is important to share with your doctor any concerns or preferences.
Depending on the tooth that is removed neighboring teeth may shift, causing problems with chewing or with your jaw joint function. To avoid these complications, your dentist will likely recommend and encourage you to replace the extracted tooth.
