Halitosis (Bad Breath)

Halitosis or bad breath is a social turn off. It is a problem that is easy to get rid of most of the time. The number one cause of halitosis is bacterial plaque and food particles on the teeth, which decay and support the growth of bacteria. Bacteria excrete compounds with a bad odor. Keeping your teeth clean is the simple solution to freshen your breath in this case. Bad breath may be caused by certain foods (eg., onions, garlic), coffee or tobacco use. Additional causes of bad breath are listed below, these are divided into oral and systemic (non-oral) causes.

Oral Causes

Oral causes of bad breath comprise 90% of the cases of bad breath. These include:

  • Periodontal (gum) disease, infection of the gums. Some additional signs of periodontal disease are red, swollen or tender gums that bleed when you brush or floss, painful gums, or loose teeth.
  • Plaque, that sticky substance, comprised of bacteria, which adheres to the surfaces of your teeth and gumline.
  • Microorganisms on surface of tongue. The warm, moist environment in the mouth is ideal for growth of microorganisms.
  • Dry Mouth. The saliva plays a role in washing bacteria and odors away from the teeth and is important in the digestion process. Dry mouth may be caused by salivary gland problems, medications or "mouth breathing".
  • Broken fillings, crowns or teeth that retain bacteria
  • Unclean dentures harboring food particles will support bacterial growth.
  • Cancerous oral lesions
  • Throat Infections
  • Cleft Palate
  • Tooth Decay

Systemic Causes

Systemic or non-oral causes of bad breath comprise the other 10% of cases of halitosis. If your dentist suspects one of these causes, you may be referred to your physician. These include:

  • Renal or hepatic failure
  • Carcinomas
  • Diabetes
  • Respiratory tract infections
  • Cirrhosis of the liver

If you have a recurrent problem with bad breath that proper brushing and flossing doesn't take care of please make an appointment with your dentist or discuss your concern with us at your next hygiene visit.
