Bad breath (Halitosis) can have a number of causes. It may be a sign of tooth problems such as a cavity or cracked tooth or it can be caused by untreated gum disease. A dental examination will reveal such problems and they can be treated easily.
If no dental cause is identified, sometimes brushing the surface of the tongue when you are brushing your teeth may help.
