I got my molars extracted today and was spitting a lot for 6hours until i read it wasn't good. how much risk am i in ofgetting a dry socket?

SHOULDN'T WORRY: Although excessive bleeding is not desirable, by itself isn't a sign of possible dry socket.But, if the blood clot doesn't' organize well due to too much rinse or something gets inside, or mostly, not enough blood, there could happen a dry socket usually getting painful at the 5th day after the extraction(s).

Closer to 20%: In general, you have a 10-20% risks of a dry socket after an extraction. Towards the higher end when lower molars are taken out. If you caused the blood clots forming to dislodge, you will be at an even higher risk. It is best to avoid anything that causes suction for the 1st 24-36 hours in order to avoid this. If things feel better for the 1st 3 days and then get worse, call your dentist.

Very likely: Following an extraction, protecting the blood clot in the socket for the first 24 hours in very important. Biting down on the gauze for a few hours to stop the bleeding and start the clotting. Then you need to let the site alone to heal. No spitting, rinsing, drinking through a straw, smoking, drinking hot liquids, or anything that can dissolve or dislodge the clot to prevent a dry socket.
