Causes of Bad Breath

Halitosis, also known as bad breath, is caused mainly by poor dental hygiene, but it can also be a sign of more serious health problems.

The most common cause of bad breath is poor dental hygiene. When food particles and bacteria aren’t removed from teeth, they can build up over time and cause a foul odor. However, there are other causes as well.

Bad breath can also be caused by the following:


Cavities are holes in teeth that can trap food particles. When food is trapped, it can’t pass through your digestive system. Instead, it becomes food for bacteria, which start to multiply. Their waste is what causes bad breath.

Cavities also weaken teeth. More damage can occur when chewing and biting, which over time leads to tooth loss.

Gum Disease

Gum disease is one of the most common causes of bad breath. Bacteria that live in the mouth will collect on teeth and gums, causing the gums to become inflamed and red. As gum disease progresses, the gums will become loose and eventually separate from the teeth. This will create pockets between the teeth and gums, where debris and bacteria will accumulate.

Tobacco Use

Tobacco use is one of the most significant causes of bad breath. According to the Centers for Disease Control and Prevention, smoking or using chewing tobacco can cause bad breath.

Tobacco products contain chemicals that cause odorous compounds to stick to the teeth. The smell can be particularly bad in people who smoke or chew tobacco and then drink alcohol.

Tobacco can also be harmful to oral and overall health. It can cause gum disease, tooth decay, and oral cancer. Those who smoke are more likely to have gum disease and tooth decay.

Diet and Nutrition

Maintaining a healthy diet is a cornerstone of oral health. Regularly eating sugary foods and drinks can lead to cavities and gum disease. Additionally, food particles and bacteria can get lodged between teeth, causing halitosis. Staying hydrated is also important as saliva helps wash away bacteria and food particles in the mouth.

Medications and Supplements

Many medications cause dry mouth, which can result in halitosis. Be sure to drink plenty of water while taking any prescription medication. Also, avoid medications with alcohol in them.

Medical Conditions and Illnesses

Bad breath can be a symptom of many common medical conditions. Although bad breath isn’t usually considered a serious medical issue, it can be a sign that something more serious is wrong. If you experience chronic bad breath, see your dentist and rule out any underlying medical problems.
