How to stop blood from wisdom teeth

After wisdom-tooth removal, steady pressure from folded gauze helps a normal clot form; persistent or heavy bleeding needs urgent dental assessment.

The extraction socket contains small blood vessels that should seal with a blood clot. Spitting, vigorous rinsing, smoking, alcohol, heat, or disturbing the socket can dislodge the clot and restart bleeding.

Sit upright, place clean folded gauze directly over the socket, and bite with firm continuous pressure for the interval given by the dental team. Replace it only when soaked, avoid probing the socket, and follow the prescribed instructions.

Contact the extracting dentist urgently if bleeding continues despite firm pressure, repeatedly fills the mouth, or comes with faintness, worsening swelling, fever, or trouble breathing.

Ask whether the clot appears stable, which medicines or medical conditions could affect bleeding, and where to go if it restarts outside clinic hours.
