Fresh Breath: Frequently Asked Questions

Can Bad Breath Signal Underlying Health Problems?

Yes, persistent bad breath may be a by-product of other medical conditions. Slightly fruity breath that isn’t wholly pleasant or offensive is a tell-tale sign of diabetes, while a strong, ammonia scent has been linked to kidney disease.

Periodontal diseases like gingivitis can cause bad breath because of the presence of excess bacteria in the mouth. And dry mouth, which causes a decrease in saliva, leaves your mouth unable to naturally flush bacteria and food particles from your teeth and gums before they break down and start to decay.

If you’re worried your bad breath might be a sign of a bigger issue, or if you’re just unable to control it yourself by brushing, flossing and rinsing, talk to your dentist.

What Habits Can Cause Bad Breath?

When it comes to habits that can cause bad breath, few rank higher than tobacco use. Just the act of smoking alone, not to mention the associated health risks. Having a high-sugar diet doesn’t help, either; the natural bacteria in your mouth will feast on the excess sugars and redecorate your teeth and gums with bacteria build-up. Low-calorie diets encourage rapid breakdown of body fat, resulting in ketoacidosis, a condition that gives breath a fruity smell. People who skip meals regularly run a different kind of risk: chewing helps stimulate saliva, which helps prevent your mouth from getting dry and smelling stale. Dry mouth also affects people who regularly breathe through their mouths, putting them in the unenviable position of having bad breath. Finally, people who are overstressed can wind up having unpleasant breath.

Does Chewing Gum Really Help Banish Bad Breath?

Yes and no. Since bad breath is often caused by dry mouth, chewing sugar-free gum can be a great way to get those saliva glands going. Not only will it help to flush out bacteria, saliva also helps usher unwanted food particles from your mouth before they can break down in your mouth.

Sweets and mints that are loaded with sugar, however, are not going to help. They may mask the odour, but they won’t kill the bacteria that are causing your breath to smell. That’s because sugary foods are the main foods that bacteria thrive on to produce acids, which then contribute to tooth decay.

Your best bet is to brush, floss and rinse twice daily. This will ensure your mouth is optimally clean.
