You have my deepest sympathies Annie.
I have to take some quite strong blood thinners, But I didn't think much of it when I went the dentists to have 2 extractions. He's a very good dentist & knew about my health probs so he made me wait 20 mins longer than usual to make sure the bleeding had stopped & I left at about 1pm.
But on my way home I sneezed & they started bleeding again, to cut a long story short, after loosing over a pint of blood I went to the A & E department at around 10pm where I was fast tracked to the dental department, they had to call in a consultant from Edinburgh to do some special stitches & I left there at 1.30am.
It took another 3 weeks for the sockets to heal.
Congealing blood in your mouth feels like cobwebs & is quite hard to get rid of!
