What Causes Bad Breath and What You Can Do About It

Fresh breath is something that everyone can appreciate. For some, however, it’s more difficult to achieve than for others. If you suffer from bad breath, it’s important to first identify the cause before any treatment can be had.

Poor oral hygiene

A major cause of bad breath is poor oral hygiene. Bad breath is caused by certain types of oral bacteria. When the mouth is poorly maintained, these bacteria are allowed to flourish, leading to the development of bad breath. To improve the freshness of your breath, it’s important to keep a good oral hygiene routine that includes brushing twice a day (preferably with a fluoride toothpaste) and flossing once a day. A tongue scraper gives an extra boost in cleaning to remove bacteria and food debris from your tongue.

Oral diseases

Infections can be another source of bad odors in the mouth. Tooth decay and gum disease are two examples of diseases that can cause bad breath. Additionally, if an old filling wears out, bacteria can reinfect that tooth, resulting in renewed decay. Besides bad breath, signs that you may be suffering from an oral disease include tooth pain, bleeding, and puffy gums. If you notice any of these signs, it’s important to see your dentist at Bishara Dental in Houston, TX as soon as possible.


This is probably a fairly obvious cause of bad breath: if you eat smelly foods, you’ll have smelly breath. Certain pungent foods such as onion and garlic are especially problematic because, once they are digested, odor-producing substances from those foods enter your bloodstream and proceed to your lungs. If you think that dietary habits might be the cause of your bad breath, try refraining from eating certain foods (at least temporarily) to see if your breath improves.

Dry mouth

One job of saliva is to help cleanse your mouth. When the mouth isn’t sufficiently lubricated, bad breath results. This is the case when you get “morning breath,” but some people naturally do not produce enough saliva throughout the day. Many types of medication also have dry mouth as a side effect. If you notice that you are experiencing dry mouth as a result of a medication, be sure to let your doctor know. Staying hydrated throughout the day can help with dry mouth.


Smoking causes bad breath in two ways: first by producing a bad odor in general and also by reducing the flow of saliva and promoting gum disease. For this reason, and many others, it’s a good idea to quit smoking.
