Item #1 on my Dentist's Post-Op Instruction Sheet addresses bleeding and you can read it here:
Remember that you probably have a lot of salivation going on right now too which may be making it seem like you are bleeding more than you actually are. Keeping your head elevated a bit can help too. Ice is good for swelling and the cold will constrict the blood vessels and help stop the bleeding.
Call the Dentist if you're concerned.
I bled alot after Eday for a good few hours and then it slowed up a bit for the majority of the day. Keep in mind that the blood mixed with saliva looks like more than it is.
You can also use tea bags soaked in warm water and drained to bite on with even pressure to slow the bleeding.
Please dont panic, this scares us all.
Also here is a link about using Tea Bags to assist clotting. I didn't do this, but others have used this method.
Sleep with your head up, a drool towel and you are going to be okay Christina.
I know this is so scary gal, we are all right here if you need us.
I bled for 12 hours and awoke twice in a puddle of blood....I was thinking I better go to e.r. then it stopped...pretty weak afterwards
