Take the 2-minute tour ×  When we have an external wound the
wound generally tents to clot and there is a layer of solid scab
formed.  Now,Yesterday while brushing my teeth i somehow hurt my
gums and it got all bloody but didn't clot neither did it pain
just after the accident  after maybe like 12 or 15 hrs later i
have trouble opening my lips and when i looked at the spot in
the mirror the gum tissue around and on the wound had become a
White/Yellowish color.  Our Mouth are supposed to be the most
contaminated regions on the human body so how come these mouth
wounds heal in just about a week and don't get infected .  what
is the healing mechanism found in the mouth tissue cause i
figure its completely different from the process on the external
body wounds  share|improve this question  3 Answers 3  The
mucosa ("slimey" skin) of course has different properties from
your epidermis (outer skin) but the wound healing process is
pretty much the same; the blood clotting process might be
different though. About this
