Blood and water oozing out after tooth extraction is usually normal. It is normal that blood may ooze from the extraction socket for 2 to 3 days after any tooth extraction, mixed with saliva, which may present as blood. Bleeding occurs when small blood vessels in the bone and soft tissue in the extraction socket rupture during tooth extraction. There may be blood oozing from the extraction socket for 2~3 days after tooth extraction, and patients often mistakenly think that there is a lot of bleeding and are nervous and fearful due to the mixing of blood with a lot of saliva, and the actual bleeding is mostly within 2 milliliters, which is normal. If accompanied by gingival tearing, residual inflammatory granulation tissue in the extraction socket, active bleeding, it is recommended to go to the hospital in a timely manner, improve the examination to clarify the cause of the disease, under the guidance of the doctor to give targeted treatment or treatment.
