Read your query. Dislogdement of the clot in anyone or more socket can be the cause for the presence of blood clot. Relax and if there is no more bleeding from the socket. If there is bleeding keep a gauze and bite firmly to stop the bleeding. Follow the post extraction instruction properly. Avoid vigorous gargling though continue with the salt water gargling. Do not use straw for a while and use a soft diet. Continue with medicines as prescribed. Hope this was useful. Thanks and regards.
