This time is generally about 1 to 3 weeks.

Gelfoam is an antigen-free collagen material that can be degraded and absorbed by human tissue. It has strong water absorption and can be used to stop bleeding in bleeding wounds. Especially when wisdom teeth are extracted, the trauma is relatively large and the bleeding is relatively large. During the tooth extraction process, gelatin sponge stops bleeding, effectively reducing the amount and time of bleeding.

The time it takes for gelatin sponge to be absorbed varies from person to person. If the wisdom tooth wound is too large, the larger the amount of gelatin sponge used, the longer it will take for it to be completely absorbed by the tissue. It usually takes two to three weeks. For wisdom teeth with relatively small incisions, less gelatin sponge is put in, and it is quickly absorbed by the tissue. It can usually be absorbed in about a week.
