Anti-coagulants are required after stenting, and it is generally recommended that teeth be extracted 1 year after the surgery, or 3 months after the surgery if the dental disease is severe. After the stent surgery, you need to follow the doctor’s prescription to take aspirin, clopidogrel anticoagulant medication for 1 year, it is not recommended to stop taking the medication during this period if it is not necessary, in order to avoid an increase in cardiovascular burden. There will be bleeding during the extraction process, if you take anticoagulant drugs are likely to prolong the hemostasis time, or even easy to hemorrhage, anticoagulant drugs should be discontinued 5 to 7 days before extraction. Therefore, if it is not necessary, it is recommended to consider tooth extraction 1 year after surgery. However, if the tooth pain is intolerable and the condition of the stent is stable after surgery, the tooth can be extracted after seeking the doctor’s consent.
