You can drink water 2 hours after wisdom tooth extraction, but you need to pay attention to the point that the temperature of the water should not be too hot. However, you should be careful not to drink water that is too hot, because the temperature of the water may be too hot to stimulate the newly formed extraction wound, causing the blood vessels in the extraction wound to dilate and the risk of bleeding. Generally, the extraction doctor will advise the patient to eat and drink 2 hours after the extraction, mainly because of the anesthetic. The anesthetic drug commonly used for tooth extraction has an approximate duration of action of about 2 hours. During the time of action of the anesthetic drug, the patient’s mouth will feel less sensitive, and at this time, there is a possibility of cheek biting, tongue biting or scalding when eating, the chance of which is not very high, but it is better to avoid it.
