Wisdom teeth extractions are a fairly common procedure. Wisdom teeth often cause problems as they are trying to protrude through the gums. When a wisdom tooth is impacted, it means the tooth is coming in at an angle and not straight through the gum line. This can cause infection, pain, and other problems. When a wisdom tooth only emerges partially, a flap of skin, called an operculum, may form over the tooth. This can make the tooth hard to clean, and pieces of food may be caught under the skin. This makes it easy for an infection, called pericoronitis, to develop and causes swelling and pain in the area.
Lower infected wisdom teeth have the potential to develop a “dry socket” after removal. This is caused by the loss of the blood clot from the extraction site. You will be given instructions on how to best prevent it from happening.
