I had your problem this May. I took LI JUN SHA for a week. It works. But that hurts my stomach. You need to take it 3-4 pills per 4 hours,insist on it, do not stop until a week.

after I recover, i use salt water to clean my mouth after brush my teeth for a month and if neccessary, keep this habit for half a year. You know that action: you bend your head to sky, and "wo lu wo lu wo lu"for 30 seconds.

Sorry i do not have chinese input in my office.
