Bad breath is an unpleasant odor from the mouth that annoys and embarrasses others and affects normal interpersonal and emotional communication; more importantly, it can be an alarm bell for your health.

Patients with sinus or lung infections, bronchitis, diabetes, and certain liver or kidney diseases may all have bad breath. If your dentist tells you that there is nothing wrong with your mouth, then see your community general practitioner for help. If you find you have bad breath when you wake up in the morning, try brushing your tongue when you brush your teeth? Making sure you brush your teeth twice a day for three minutes each time, as well as flossing once a day, is the first line of defence against bad breath.
