My sister said it feels like her gums bleed after she runs?

is that possible?

My sister said it feels like her gums bleed after she runs?
hmmm let me think.. ill go by what the first two said she probably bites down on the teeth really hard or grinds her teeth together and she dosent even notice it, it could be a bad habitt maybe she zones out and dosent notice. I would say tell her to get her a mouth guard thats pretty damaging to the teeth and gums. good luck

Maybe she bites down on them when she runs?
Reply:WOW! thats really od. But mabey she bites down on them with out even thinking about it. If this happens again, tell her to wear a mouth gard or something.....that might help!
