Doctor outlines the common causes and treatments for bad breath

RAHWAY, N.J., June 15, 2023 /PRNewswire/ -- Halitosis – more commonly known as bad breath – can have serious social consequences. But in a new editorial from MerckManuals.com, one expert points out that halitosis may also be a sign of other, underlying medical conditions.

Bernard J. Hennessy, DDS, Texas A&M University, College of Dentistry, shares his steps for identifying the cause of halitosis as well as treating and eliminating it.

Identify the Source

Bad breath is most often caused by the action of certain mouth bacteria, Hennessy explains. These bacteria break down certain amino acids into foul-smelling substances. Typically, there are things you can try at home before seeing a doctor, including better dental hygiene habits and avoiding odor-producing things like garlic, onions, alcohol, and tobacco.

In some cases, bad breath warrants a trip to the doctor to determine the cause. Hennessy suggests starting by bringing it up with your dentist. The dentist will ask about your medical history and then do an examination. About 9 in 10 cases of halitosis are caused by issues in the mouth.

Maintain Good Habits at Home

For the majority of cases of bad breath originating in the mouth, dentists will recommend that you increase your at-home dental care regimen. At a minimum, that means brushing at least twice a day. Hennessy also recommends flossing, brushing your tongue, and using mouthwash.

Keep Up with Regular Cleanings

Regular dental cleanings are an essential part of good oral hygiene, Hennessy says. While lack of access remains a challenge for many individuals and families, it's a best practice to see a dentist for a cleaning at least twice a year, and that's especially true for individuals suffering from bad breath.

Rule Out Other Causes

In a small number of cases, bad breath may be caused by more serious underlying medical conditions, including liver and kidney failure and uncontrolled diabetes. In these cases, the scent of the odor can be a useful indicator.

But in a vast majority of cases, Hennessy says, halitosis and bad breath can be addressed with good oral hygiene habits, including consistent at-home care and regular cleanings. Not only can these steps improve your breath and your teeth, they can improve your overall health as well.
