Cotton balls placed in the cavity after tooth extraction can be spit out after half an hour due to blood and saliva soaking, but if a hemostatic gel sponge is placed in the cavity, it does not need to be removed.
A cotton ball or gauze ball the size of a knuckle is usually placed over the cavity to stop bleeding after a tooth extraction, and the blood clot is usually asked to spit itself out after 30 to 40 minutes after it has formed. However, sometimes the doctor will also insert a hemostatic gelatin sponge into the cavity after tooth extraction, and use gauze ball or cotton ball to press on the top to stop bleeding, and the hemostatic gelatin sponge will be absorbed by the body without removing it. It is recommended to consult your dentist.
Tooth extraction should follow the doctor’s instructions to make the correct use of cotton balls or cotton balls to stop bleeding, usually need to be observed for half an hour before leaving the hospital.
