Visiting 100 year old gran. She is on blood thinners. Her teeth are pretty rotten - refused dentist for a good few years Obviously her gum is bleeding somewhere. It is gushing with blood. I’ve got her to open her mouth but can’t see where it’s bleeding her whole mouth is full of congealed blood. . I’ve tried a soaked tissue. But still bleeding. Any tips. She is panicking which is making it worse.
