It is best not to drink tea immediately after tooth extraction, after the bleeding from the wound stops, you can take a small sip of tea, the tea should not be too hot, and you need to pay attention to protect the blood clot. After tooth extraction, it is usually necessary to bite the cotton roll for 30~40 minutes to stop bleeding, and then you can spit out the cotton roll. However, do not drink water for 2 hours, after which you can drink tea. It should be noted that too high a temperature of tea is not conducive to blood clotting, in order to promote the formation of blood clots should try to drink room temperature tea. In addition, using a straw to drink tea or using tea to rinse your mouth may cause the blood clot to dislodge, resulting in non-healing wounds or infections causing dry socket. If there are symptoms such as bleeding or infection after tooth extraction, it is recommended to go to the hospital in time for targeted treatment with the help of the doctor.
