If you still bleed 6 hours after tooth extraction, you should judge whether it is normal according to the amount of bleeding. Six hours after tooth extraction, if a small amount of blood appears in the mouth, it is normal; if a large amount of active bleeding occurs and a red blood clot continues to appear, it is abnormal and should be promptly seen in the hospital. After tooth extraction, there will be a relatively large trauma and blood seepage can occur, so the doctor will give the patient the treatment of biting cotton gauze and cotton roll after tooth extraction, and it is recommended that the patient bite for 30-40 minutes, which usually has the effect of stopping bleeding. After tooth extraction, there will still be saliva containing blood, which is normal within 1-2 days. However, if the bleeding is relatively large and difficult to stop, it is recommended to consult the dentistry department of the hospital where the tooth was extracted or the local hospital in time. After tooth extraction, patients are advised to eat warm, cool and soft food, such as ice cream, ice porridge, etc. If necessary, ice packs can be applied to help stop the bleeding and reduce the swelling of the wound.
