Like all forms of surgery, wisdom teeth extraction surgery carries the risk of potential complications. Some of these potential complications are quite rare, while others are very common. In general, wisdom teeth extraction is considered a very safe surgical procedure, if it is carried out by a professional dentist or oral surgeon. Most of the patients undergo the wisdom tooth extraction to remove the infected wisdom tooth.
Here are the some of the possible complications that can result from extracting wisdom teeth:
Swelling, wisdom tooth infection, discoloration of the face, point tenderness, pain and discomfort
These are the most common side effects and complications of having wisdom tooth extraction surgery. As many as 50% of people who have wisdom teeth extraction surgery performed will experience these symptoms. In general, these symptoms will be present for about 48 hours after surgery and the majority of patients that reported having such symptoms did not say that they were overly serious or painful. If these symptoms, especially swelling and pain, do not dissipate after 48 hours or so, they could be a sign of infection.
Any time a surgery is performed to remove a tooth there will be bleeding involved. This bleeding will usually stop on its own after about six hours. In very rare cases, patients may experience serious blood loss after the six-hour period is over. If severe blood loss occurs, the patient should seek immediate medical attention. Many patients will experience occasional bleeding during the several days of recovery, but this bleeding is usually very minor and the result of tearing or harming the wound.
Trismus or difficulty opening the mouth
Some patients will experience difficulty opening their mouth as wide as they are used to after having their wisdom teeth removed. Some possible causes for this can include an injury to the pterygoid muscle by a needle, having the patient’s mouth stretched for too long during the surgery, hematomas, inflammation and swelling. This trismus is usually temporary and will go away on its own after a few days.
Dry socket is described as a throbbing pain at the tooth removal site. This usually occurs when a blood clot fails to properly form in the socket, causing the nerves to continuously fire. This sharp pain can arrive several days after the extraction has taken place. This inflammation is often confused with an infection, but unlike an infection dry socket will go away on its own in a week or two.
Occasionally, when the upper wisdom teeth are removed they can create a hole leading into the sinus cavity. A material called gelform is usually used to block the hole and help prevent infections. If an infection occurs in the sinus cavity, it may require additional surgery.
