Does your body absorb the blood clot from wisdom teeth removal?

Yes : First the clot becomes the scaffolding for healing, then the clot is resorbed as bone grows back into the socket.

Yes and no: After your tooth is removed the clot will form in the socket. This will usually dissolve (lyse) over time sort of like how a scab comes off after you have a cut or abrasion of your skin. If the socket isn't open for the lysed clot to come out the body can resorb some of the clot, but usually as the clot breaks down it leaks out of the socket.
