The key to solving the problem of bad breath is finding the cause. The follow can cause bad breath;
-chronic mouth ulcers
-problem arising from the oesophagus
-renal or liver problems.
Even though they are enormous, I can assure you that if you see your Doctor, he/she will be able to identify the likely cause.
For now, ensure you brush your mouth at least twice daily and always rinse your mouth after taking snacks or fruits. Take care
