It is generally recommended to avoid using straws for at least one week after wisdom teeth removal. This is because the suction created by using a straw can dislodge the blood clot at the extraction site, potentially leading to painful complications such as dry socket. After the first week, if healing is progressing well with no excessive pain, swelling, or bleeding, straws may be used cautiously but it is best to consult your oral surgeon or dentist for personalized advice. Continuing to avoid straws for the initial healing period helps ensure proper stabilization of the clot and reduces the risk of infection and other complications.
