Do blood clots form deep within the roots of an extraction site or on top? the clot visible on the surface is only partly covering the hole! its day3.

Possibly both!: The blood clot forms from the base of the socket; additional clot may form from the surface. Sometimes the blood clot in the socket breaks loose, exposing the bone in the socket. This is called a dry socket and can be painful. If this happens your dentist will likely place a sedative dressing over the socket to protect it until a new clot forms. Contact your dentist with any questions:)
