It is usually one year after a heart stent procedure before teeth can be extracted. In case of coronary heart disease causing arterial blockage or arterial stenosis, installation of cardiac stent is the first choice. However, after cardiac stent surgery, one year of dual antiplatelet drugs, such as aspirin in combination with clopidogrel, is also taken under the guidance of a medical professional, mainly to prevent blood clots from forming. If teeth are extracted while taking the dual antiplatelet drugs, there is a risk of bleeding. Therefore, if tooth extraction is needed after cardiac stent surgery, it is recommended to consult with the attending physician in a timely manner as to whether the medication can be discontinued, and after discontinuing the dual antiplatelet medication for a period of time, then the tooth extraction should be handled. Before tooth extraction, it is important to understand the relevant precautions in detail from the doctor so as not to cause unnecessary risks.
