Gelatin sponge is used to stop bleeding after tooth extraction. There are two kinds. One is an absorbent gelatin sponge, which is absorbed by itself and does not need to be taken out artificially. Generally, it will be completely absorbed after 5 to 7 days. You don't need to get it. The other is not absorbable. Those that cannot be absorbed can be taken out by themselves in about 5 days. However, tooth extraction is generally absorbable. So don't worry. Stomatologists pass by in a low-key way ~ ~ ~ and hope to adopt it.
