try the following:
1. 1/2 teaspoon table salt into 1 glass (~8 oz) of boiled water
better with normal saline from drug store
rinse your mouth thoroughly when water cools down.
if you are bleeding then
2. get some sterile gause from drug store. wash your hands with soap then
roll the gause into a ball of 2cm X 4cm X 1.5cm (just give you a sense of
how big it should be, don't worry about the exact number) stuff the gause-
ball into the site of bleeding and bite on it hard to stop
