How long does it take to bite a cotton ball?

Generally, we recommend biting cotton balls for half an hour after pulling out teeth. After pulling out teeth, tooth extraction wounds will be covered with blood. The purpose of biting cotton balls is to let blood clot and stop bleeding. only by forming high-quality blood clots can we protect tooth extraction wounds. External stimuli and external bacteria are not easy to enter tooth extraction wounds. Therefore, it is not easy to show postoperative infection phenomenon. Therefore, under normal circumstances after pulling out teeth, biting cotton balls is biting for half an hour. Of course, if we pull out loose baby teeth, we don't normally bite for half an hour, we just teach the patient 15 minutes, so 15 minutes of biting cotton balls can spit out. After pulling out the teeth, half an hour or 15 minutes after the deciduous teeth are pulled out, the cotton balls will be spit out, so our doctor must instruct the patient to spit cotton balls, some patients may not know to spit cotton balls, so some patients after 2 to 3 days cotton balls are still in the mouth, so this is very dangerous, the doctor must explain well.
