Blood Clots After Wisdom Teeth Extraction: Risks & Prevention

Yes, it is possible to develop a blood clot in your leg or lungs ( deep venous thrombosis, or DVT) after wisdom teeth extraction. However, this is a rare complication and occurs in less than 1% of cases. The risk of DVT is higher in individuals with certain risk factors, such as a personal or family history of blood clots, obesity, smoking, or prolonged immobility.

Blood clots typically occur when blood pools in a vein and clots, leading to a blockage in blood flow. During wisdom teeth extraction, injury to the blood vessels in your mouth can sometimes lead to the formation of a clot. This clot can then travel through the bloodstream to larger veins in the legs or the lungs, causing DVT or pulmonary embolism (PE), respectively.

To minimize your risk of developing a blood clot after wisdom teeth extraction, be sure to follow your dentist's instructions carefully. This includes taking any prescribed medications, avoiding strenuous activities, and maintaining proper hydration. If you experience any symptoms of a blood clot, such as swelling, pain, or shortness of breath, seek immediate medical attention.
