After a tooth extraction, it is generally recommended to avoid using a straw for at least 7 days. The reason for this is that using a straw creates suction in your mouth, which can dislodge the blood clot that forms in the extraction socket. This blood clot is essential for protecting the bone and nerves underneath and promoting healing. If the clot is dislodged, it can lead to a painful condition called dry socket, delayed healing, increased bleeding, and risk of infection. For simple tooth extractions, some dentists may allow using a straw after about 3 days, but for more complex extractions, like impacted wisdom teeth, waiting a full 7 days or even longer is safer. In some cases, your dentist may advise avoiding straws for up to 10 to 14 days depending on your individual healing process. Therefore, to ensure a safe recovery and avoid complications, you should wait at least a week before using a straw after a tooth extraction, and always follow the specific advice given by your dentist based on your situation.
