When people have tetanus why cant they open their mouth?
tetanus has the tenancy to cause lock jaw if left untreated i.e
un-innoculated persons etc. lock jaw is where the muscles around
the jaw tence up and cause a closed mouth i.e lock jaw effect and
the person will need to go to the doctors/hospital and have there
jaw injected with a muscle relaxant and "pry" the jaw open again,
if lock jaw is not treated immediately then cracked/smashed teeth
can be a result of to much down and upward pressure on the teeth.
very nasty, cheers
