Don’t let bad breath -- also known as halitosis -- keep you from getting close. If you and your dentist know what’s causing it, you can treat it.
What Causes Bad Breath?
Common causes of bad breath include:
- Food odors
- Poor oral hygiene
- Gum disease
- Tooth decay
- Dry mouth
- Postnasal drip and sinus infections
- Acid reflux
- Poorly fitted dental appliances
Do Good Dental Habits Really Help?
Yes. If you don't brush and floss daily (or clean your dentures), bits of food can remain in your mouth. The food promotes bacterial growth between teeth, around the gums, and on the tongue. The result? Bad breath.
If your breath bothers you, talk to your dentist. He should give you a thorough exam and cleaning, followed by a review of your at-home cleaning routine. He may suggest a mouthwash and rinses to kill the bacteria that cause plaque, a filmy buildup on your teeth.
Could I Have Gum Disease?
Ongoing bad breath or a nasty taste in your mouth may be a warning sign of gum disease, which is caused by plaque. The bacteria it harbors create toxins that irritate the gums and cause a bad smell. If this condition goes untreated, it can damage the gums and bone that supports the teeth.
Does What I Eat Matter?
As foods are digested, odor-causing chemicals are absorbed into your bloodstream. They move to your lungs and are given off in your breath. If you eat smelly foods like garlic or onions, brushing, flossing, and using mouthwash can cover up the aroma temporarily. However, it won’t go away completely until the foods have passed through your body. The key here is awareness. Know what foods make your breath reek, and stay away from them.
Can Dry Mouth Play a Role?
Dry mouth, also called xerostomia, can affect your breath. Saliva moistens and cleanses your mouth. It neutralizes acids produced by plaque and washes away dead cells from your tongue, gums, and cheeks. If not removed, these cells decompose, creating a foul odor. Causes of dryness include medication, salivary gland problems, or continuous breathing through the mouth.
