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.
