There are over 400 medications which list dry mouth as a potential adverse side effect.
So if you are currently taken medications and you are suffering from bad breath, you might want to check back in with your doctor to see if your medications are the root cause. Or perhaps check on the medicine's official website.
Some of the medications associated with dry mouth and therefore perhaps chronic bad breath include:
1. Some anti-depressants
2. Blood pressure medications
3. Drugs for urinary disorders such as incontinence
4. Medication for Parkinson's disease
Why can dry mouth cause bad breath? The mouth consists of soft tissues and if they are dry, they are easily irritated which makes it more susceptible to infections. Saliva is a natural cleaning agent, so you need to have saliva around to keep the mouth healthy and clean.
