Postpartum hemorrhage is a common complication after tooth extraction. Many systemic and local factors can cause bleeding after tooth extraction. Reasonable selection and application of local hemostatic material for filling extraction socket is a good way to reduce and prevent post-extraction bleeding，and reduce the suffering of patients. With the development of oral materials science，more and more hemostatic materials are used to treat and prevent bleeding after tooth extraction. All kinds of hemostatic materials for filling extraction socket have a certain hemostatic effect. In clinical operation，our treatment should be based on the situation of tooth socket bleeding and the patient's general and economic conditions. In order to help clinicians to choose and apply hemostatic material，we will introduce the commonly used hemostatic materials，and analyze the characteristics of commonly used tooth extraction hemostatic materials in this paper.
