The first thing you should do is to check the amount of blood that is being bled. Generally, half an hour after the wisdom tooth is removed is the time when the blood clot gradually begins to form. During this time, theoretically, the extraction wound will have normal blood seepage, but during the corresponding time period, the extraction doctor will instruct the patient to bite the sterile cotton balls or sterile cotton rolls tightly on the extraction wound site. Therefore, during this period of time, there will be no obvious bleeding. After this period of time, it is also normal to have blood in the sputum of the extraction wound within 24h after the extraction. That is, the patient may spit out sputum with 1 thread of blood, this situation is also normal, there is no need to worry too much. However, if it is not the above cases, but there is obvious blood seepage after tooth extraction, continuous and uninterrupted, in this case, it is recommended that the patient go to the professional stomatology department as soon as possible, to check whether there is any tearing of the gums or rupture of small blood vessels in the extraction wound, and if necessary, it is possible to carry out the treatment of the extraction wound for two times, or use the needle and thread to pull together the wound for closure, and in the vast majority of cases, after pulling together the wound for closure, there is no need to worry too much about it. In most cases, bleeding from the extraction wound will stop after suturing.
