Poor oral hygiene and infection of gums often results in a bad odour emanating from the mouth. This is called halitosis.
Smoking can make this worse. Proper brushing of the teeth and oral care can get rid of bad breath.
HT ImageThere can be other reasons for bad breath. Colds, sinuses, throat infections or tonsils can cause bad breath.
Diseases of the stomach, liver, intestines or uncontrolled diabetes are also possible causes.
Therefore, if bad breath persists despite good dental care, you need to see a doctor.
