After wisdom teeth extraction, due to the apical blood vessels and periodontal tissues of the tear caused by the extraction wound bleeding, moderate drinking cold drinks can promote local hemostasis, and the formation of blood clots. It is important to note that when drinking cold drinks, do not use a straw or rinse your mouth with cold drinks, as this may cause the blood clot to dislodge, resulting in post-extraction pain, bleeding, infection and other complications.

If you experience any of these symptoms, it is recommended that you go to the hospital in time to receive professional treatment.
