Halitosis – or bad breath – is typically the result of poor dental hygiene; however, sometimes there are other underlying causes. These may include: gum disease, tooth decay, heavy metal buildup, infection of the respiratory tract, improper diet, constipation, smoking, fever, dieting, fasting or alcohol abuse.
Morning breath is simply the result of dehydration and lack of saliva to wash bacteria away from the mouth.
Symptoms May Include:
- Sour or metallic taste in the mouth
- Discoloration of the tongue
- Bad breath
