Not sure about what you want suggestions on. Your blood will take longer to coagulate, e.g. INR=2 means two times longer. You can get a tooth guard that will keep you from biting, they are used for people who grind their teeth.Okay, as I await valve replacement surgery (probably by the end of the month), let me query this. Because of previous dental surgeries, I now have a tendency to bite the hell out of my tongue or lower lip, which inevitably draws blood, and which also occasionally takes some time to stop. I'll ask my surgeon or cardiologist about this, but any suggestions here?
