Using bad breath spray to get rid of bad breath is unfortunately not a foolproof method. Depending on the cause of your breath condition, this popular remedy may or may not work. If you are suffering from chronic halitosis, then bad breath spray won't help eliminate it. Most of the time, it is a temporary fix and merely mask the smell. When you are in doubt, you should always check with your dentist or doctor.
Internal illness like having digestive problems could aggravate your breath condition. Often, it may be something more serious than just having bad breath.
If you have found that the cause of your bad breath is due to the bacteria in your mouth and throat, then bad breath spray will help. For that, do ensure that it is alcohol-free. Alcohol is known to dry your mouth and so you wouldn't want that.
