If your bad breath doesn’t improve despite self-care techniques, such as dietary adjustments and thorough tooth brushing, you may need to see a dentist about pursuing professional treatment. Your dentist may then inspect your mouth for signs of decay, infections, or gum disease that could be causing your bad breath
Keep in mind that short-term remedies like gum, breath mints, and mouthwash may temporarily freshen breath, but they aren’t a solution to the underlying problem. If your chronic bad breath can’t be traced to an oral problem or daily habit, you may be referred to a physician for further evaluation.
