Causes of Bad Breath
Foods and beverages: What you eat and drink can cause bad breath. Foods are absorbed into your bloodstream and move to the lungs, affecting the air you exhale. Brushing or using mouthwash can briefly mask the odour. But halitosis lasts until the culprit is no longer in your body. Common offenders include:
- Certain spices
- Orange juice or soda
Dry mouth: Saliva helps keep your mouth clean and reduces odour. If you don’t have enough of it, simply having a dry mouth can cause bad breath.
Poor dental hygiene: When you don’t thoroughly clean your teeth, gums, and tongue each day, bad breath may result from remaining bits of rotting food and the growth of bacteria in your mouth. Inflammation of the gums (gingivitis) from poor dental hygiene can also cause bad breath.
Health problems: Sometimes bad breath can signal a larger health problem, such as:
- Sinus infection
- Chronic lung infection
- Liver or kidney disease
- Gastrointestinal problems
Preventing and Treating Bad Breath
There are a number of simple things you can try to get rid of bad breath.
- Change what you eat and drink. Keep track of the foods you eat and try to:
- Avoid foods and beverages that cause bad breath.
- Drink more water.
- Suck on sugar-free mints if your mouth tends to get dry.
- Avoid tobacco use of any kind.
- Brush your teeth, gums, and tongue with a fluoride toothpaste at least twice a day. Make sure to reach the gum line as well as tooth surfaces.
- Floss at least once a day.
- Rinse with an antiseptic mouthwash twice a day.
- If you wear dentures, remove them while you sleep. Brush and soak them during the night in a disinfecting solution.
- Clean braces and retainers as directed by your dentist.
When to See Your Dentist About Bad Breath
Ask your dentist about other potential solutions for halitosis. For example, for dry mouth, your dentist might recommend artificial saliva. Also, talk to your dentist before buying halitosis kits or products for controlling bad breath.
If changes you make don’t help, the dentist may refer you to a doctor to see whether an underlying health problem could be causing the bad breath. You can also go over a list of your medications with the doctor to see if any of them could be contributing to the problem. Or, if you use tobacco, get guidance from your doctor on ways to kick the habit.
