What Causes Bad Breath?

Bad breath (or halitosis) can be put down to a number of reasons. 


A common cause for bad breath comes from the food we eat. Some foods are stronger in flavor than others such as garlic and coffee. These can linger leaving bad odors. You can improve your breath by brushing your teeth, chewing sugar free gum, or using a mouthwash. 


Tobacco products including cigarettes and chewing tobacco are other common causes of bad breath. They will also damage your oral health and significantly increase the risk of developing oral cancers and stain your teeth. Quitting these practices will greatly improve your oral health.

Oral Health Issues

Gum disease and cavities may also cause bad breath. Also, issues such as crowded teeth or braces that haven’t been fitted properly may also conditions for odors to develop. Your regular dentist will be able to provide solutions if you feel these are issues affecting your breath.


Odor causing bacteria in the mouth can also cause bad breath. If you don’t remove the food particles inside your mouth, the bacteria will multiply. The American Dental Association (ADA) suggests brushing your teeth twice a day, floss at least once, and visit the dentist every 6 months. Doing so will keep your mouth clean and reduce the level of odor-causing bacteria.

Dry Mouth

You could speak to your doctor if you feel that your medication is causing bad breath. They may be able to switch your medications.

You may need to be honest about your habits to discover what may be causing the halitosis.  Your doctor and dentist should be able to help you too. Following basic oral hygiene practices and avoiding tobacco products will likely lead to a reduction in halitosis. This means that you should brush and floss regularly and visit the dentist every 6 months.  You will also see an improvement in your oral hygiene as you eliminate the bacteria in your mouth.
