What Causes Halitosis?
Bacteria and plaque build up are the most common causes of bad breath. If you do not practice proper oral hygiene, plaque and tartar can accumulate on the teeth and gum line, attracting bacteria. The food particles and bacteria emit an unpleasant odor, and they can cause dental decay and gum disease.
Even if you practice impeccable dental hygiene, there are additional causes of halitosis, including:
- Food: Most people already know that certain foods can cause temporary bad breath. However, if you routinely eat foods like onions, garlic, and odorous spices, it could result in chronic halitosis.
- Dry mouth: Saliva plays an important role in your dental health, washing away bacteria and plaque. If you suffer from dry mouth, plaque and bacteria may linger in your mouth, even if you brush and floss regularly.
- Medications: Some medications can cause dry mouth. Others are broken down in the blood stream, and like food, they can lend an unpleasant odor to your breath.
- Smoking: Tobacco use can cause bad breath on its own. It also increases your risk for dental decay and gum disease.
Medical conditions: Certain conditions, such as pneumonia, bronchitis, diabetes, acid reflux, kidney disease, and liver disease, can cause bad breath.
