If the wisdom teeth is bleeding is it infected?

It is normal for bleeding after wisdom teeth extraction. The bleeding might come and go for 24 hours, but should not be constant in a high flow. If this is the case, call your dentist. If you don't have coton gauze anymore, you can put a wet tea bag and bite on it. It acts as a coton and it has tannic acid which slows down the bleeding. Signs of infection would be a flow of puss coming out of the hole. If you are not sure, see your dentist.
