How long should you keep gauss on a extracted tooth?

After a tooth extraction, gauze should typically be kept in place for about 30 to 45 minutes to help control bleeding. It’s important to bite down gently on the gauze to promote clot formation. If bleeding persists after this period, you can replace the gauze with a fresh piece and continue to apply pressure as needed. If bleeding continues beyond a few hours, it's advisable to contact a dentist.
