I would recommend rinse gently about 24 hours after an extraction.
When can i start swishing water into the hole itself to try and get stuff out without having to worry that one of the things i will wash out is the blood clot?
I'm not sure. It depends on how fast you heal and how extensive the surgery was. I would say you can gently rinse about 24 hrs after the extraction. I would imagine approximately a week would be okay as long as you're not intentionally trying to damage the area.
