Following a tooth extraction, a blood clot forms in the socket. This clot is typically dark red, almost black in appearance initially. Over the first few days, the clot may lighten slightly. Its texture is gelatinous, similar to a soft jelly. The size will vary depending on the size of the extracted tooth and the resulting socket. It is crucial this structure remains undisturbed.
The formation of this post-extraction coagulum is essential for proper healing. It acts as a protective barrier, preventing bacteria from entering the open wound and minimizing the risk of infection. Furthermore, it provides a scaffold for new tissue growth, facilitating the regeneration of bone and gum tissue required to close the extraction site. Historically, methods to encourage clot formation have been a cornerstone of post-operative dental care.
