Main Reasons for Halitosis

Anything that causes a buildup of bacteria or dry mouth can lead to halitosis. Many products designed to fight bad breath only do so temporarily because they simply cover up the odor. To truly take care of chronic bad breath, you need to address the cause.

Some of the reasons you might be having bad breath are due to the following:

Your Diet

We’re all familiar with the fact that eating foods with strong odors can result in bad breath. This is because food gets broken down in your mouth, absorbed into your bloodstream, and moves to your lungs. The smell won’t completely go away until it's passed through your body.

Not eating often enough can also cause bad breath. This happens when your body breaks down fat and releases chemicals that can affect your breath.

Poor Dental Habits

Not brushing properly can cause food particles to remain in your mouth and promote bacterial growth between your teeth and on your tongue. Over time, this will cause halitosis. Poor dental hygiene can also cause your gums to become inflamed, which is another reason your breath might smell bad.


Have you ever heard of smoker’s breath? There are several reasons why smoking can cause halitosis. People who regularly smoke have a stale scent from the cigarette smoke that still lingers in their throat and lungs. Not to mention it can cause dry mouth, which is known to cause bad breath.

Gum Disease

Unpleasant breath can be one of the warning symptoms of periodontal disease. This is because bacteria have built up on your teeth and have caused toxins to form.

Certain Illnesses

Diseases or illnesses that can cause dry mouth or bacteria to sit in your otolaryngological system (ears, nose, and throat) can result in bad breath. This happens when your sinuses become inflamed and regular cleaning can’t reach the bacteria. Some other conditions that cause halitosis are:

  • Seasonal allergies
  • Postnasal drip
  • Chronic acid reflux
  • Chronic sinus infections

How to Prevent Halitosis

Depending on the reason behind your bad breath, improving your oral habits should help take care of the problem. The best way to keep your breath fresh is to practice the following habits.

  • Practice good oral hygiene
  • Stay hydrated
  • Stop smoking
  • Visit your dentist regularly
