Oral Surgery Wisdom teeth extraction is often required when the tooth has grown at an angle as a result of a lack of room left in the back of the mouth when they begin to emerge. Although this procedure is not always required, individuals are advised to attend a consultation with their dentist to prevent the onset of a number of dental health problems that could occur as a result of the issue. Food and bacteria can get trapped under the gum between the gum and the partially erupted wisdom tooth that has not fully grown through the gum tissue, which could result in the development of harmful decay on the wisdom tooth and the molar tooth in front of it.
