More than 70% of teens say bad breath is an instant turnoff. About 85% say it's the most important thing to avoid when meeting someone for the first time. And while bad breath can be treated and avoided, you often don't even know that you have it!
Bad breath (called halitosis) is a common problem not only for teens, but also for everyone. So what exactly is it, what causes it, and, most importantly, how can you get rid of it?
Do you know if you can get an STD the first time you have sex? Have you heard that you can catch one by sitting on a toilet seat? Does having sex in a hot tub protect against STDs?
WebMD asked Gail Bolan, MD, director of the CDC's Division of STD Prevention, to clear up some common myths about STDs. She also has some important advice to help teens protect themselves every time they have sex.
Only trashy or slutty people get STDs.
No. These infections are equal opportunity. If you're having...
Poor hygiene (yep, you have to brush teeth more frequently)
In most cases, bad breath comes from the gums and tongue. Some bacteria in your mouth may produce compounds that result in an odor.
Certain foods, such as garlic and onions, not only leave lasting odors in your mouth, but are also absorbed into the bloodstream. The odors are then expelled from the lungs. Until these foods are eliminated from the body, mouthwash, chewing gum, and toothpaste can only mask the odors on the breath.
For some people, a dry mouth causes bad breath. Dry mouth can result from taking antihistamines for allergies or a cold, or from antidepressants. It can also result from localized infections, diabetes, gastrointestinal disturbances, or liver or kidney ailments.
The postnasal drip that streams down the back of your throat during colds, allergies, or sinus infections can result in bad breath. Sometimes, tiny food nuggets lodge in the crypts of your tonsils or on the tongue and cause a foul odor.
But most bad breath is the result of poor oral hygiene. Basically, that means you don't brush or floss frequently enough. How many times have you heard that from your dentist?
Bacteria that build up on the back of your tongue or in between your teeth are the main culprits. Certain types of bacteria love to breed on the tongue, in the crevices between your teeth, or in untreated cavities.
Finally -- yet most important -- tobacco products cause bad breath. If you smoke tobacco or chew smokeless tobacco, ask you dentist or your primary health care professional for tips on kicking the habit.
How Can I Tell if I Have Bad Breath?
Believe it or not, the most common method doesn't work to diagnose your own bad breath. Many teens think that they can blow into their hands and smell their breath. That simply doesn't work.
Instead, do this. Lick the back of your hand, let the saliva dry, then take a whiff. What you smell there is your true breath.
Another good way? If you have a trusted friend, ask them to smell your breath. Parents can also tell you if you ask.
