I have always used home remedies when possible. But I have come across situations that have called for a regular doctor. This is not said to cause fear in any way....but about 2 years ago my moms best freind had terrible breath ( which she had for several ongoing years). She ended up having a gall bladder atack and having an emergency removal. They found that her gall bladder was actually begining to turn gangrene. I'm not sure why she had no previous symptoms. I wanted to add this because its important to know the that bad breath is not always a simple solution. It can be a symptom of something extremely serious.
