What are the precautions to keep in mind after tooth extraction

After tooth extraction, first of all, you need to bite the cotton ball tightly to prevent bleeding. After one hour, spit out the cotton ball, swallow less saliva and spit less. Secondly, you can't eat anything within two hours. Don't rinse your mouth or brush your teeth within 24 hours. Don't eat hot food, so as not to cause tooth bleeding.
