What really causes bad breath?

Simply put, the main cause of bad breath is the bacteria that grow in our mouths and create an odor (bad smell) . When we don't brush our teeth properly, these bacteria thrive on food particles that get stuck between our teeth and on our tongue. The sulfur compounds released by these bacteria are what cause bad breath. Just think, if we don't rinse our mouths properly after eating, those food particles will go bad over time.

Do food and drink and our habits also affect this?

Yes, absolutely. Some foods, especially those that contain pungent oils like onions and garlic, can increase bad breath. Do you know what happens? These oils are absorbed into our bodies, carried to our lungs, and released when we exhale. That's why sometimes we can still smell garlic even after brushing our teeth. Also, smoking is a major cause of bad breath . Smoking dries out the mouth, increases the risk of gum disease, and the chemicals in tobacco directly cause bad breath.

Let's look at some myths about bad breath.

There are many myths about bad breath. But some of them are not entirely true. Let's look at some of these misconceptions.

Myth #1: "Mouthwash will completely eliminate bad breath!"

This is not entirely true. Mouthwash only temporarily suppresses the odor in the mouth. It's like wearing perfume. After a while, the odor can start coming back due to the bacteria's activity.
If you use a mouthwash, choose one that has antiseptic properties, meaning it kills germs that cause bad breath and reduces plaque . If possible, it's best to choose a product that is approved by a reputable organization. You can also ask your dentist for advice on this.

Myth #2: "I brush my teeth well, so I can't have bad breath!"

There's a little problem here. The truth is, most people only brush their teeth for a short time, like 30 to 45 seconds . That's not enough. To get all the sides and surfaces of your teeth clean, you need to brush them twice a day, for at least two minutes each time. You should also remember to brush your tongue.Because the tongue is a favorite place for bacteria to settle. Flossing is just as important as brushing your teeth. Brushing alone does not remove the food particles and plaque that get stuck between your teeth and along the gum line. Flossing is the only way to remove them completely.

Myth #3: "You can tell if you have bad breath by smelling your breath!"

This is also wrong! The way you use your throat is different when you're just breathing and when you're talking. When we talk, the smells from the back of our mouth (the main source of bad breath) are more likely to come out. This doesn't happen when we're just breathing. The other thing is, we get used to our own smells easily. So it's hard to know for sure if we have bad breath or not. Sometimes you only know if someone close to you tells you.

So how do you reduce this bad breath?

So, if you're even slightly worried about bad breath, the first thing you should do is take good care of your teeth and mouth.
  • Brush your teeth twice a day for two minutes with a good fluoride toothpaste.
  • Floss between your teeth every day.
  • Clean your tongue thoroughly. There are tongue scrapers, or you can brush your tongue with your toothbrush.
  • Using sugar -free gum or mints can also temporarily mask the odor. However, these are not a solution, just temporary relief.
  • Drink plenty of water. A dry mouth is also a cause of bad breath. Drinking water keeps the mouth moist and also washes away food particles.

What should you do if you still have bad breath even after brushing and flossing your teeth well?

If you're brushing, flossing, and getting regular cleanings, but your bad breath still isn't getting better, you may have another medical problem. For example:
  • Nasal infections such as sinusitis .
  • Gum Disease / Periodontal Disease . In this condition, the gums recede, exposing the roots of the teeth, where bacteria can accumulate and cause a bad odor.
  • Some gastrointestinal issues.
  • Some chronic medical conditions , such as diabetes mellitus, can also cause a distinctive odor from the mouth.
So, if you have such doubts,Be sure to see your dentist or family doctor. They can help you find the real cause of your bad breath and help you find the right treatment. There's no need to be ashamed or afraid. This is a problem that many people have.

Finally, the take-home message!

So, from what we've discussed, you can probably tell that bad breath isn't something to be concerned about, but it's something to be concerned about.
  • Good oral hygiene is the most important thing. Be sure to brush your teeth, floss, and brush your tongue.
  • Don't fall for the misconceptions about bad breath.
  • If everything you do doesn't reduce bad breath, definitely seek medical advice.
  • See a dentist regularly to check the health of your teeth and gums.
If you follow these things, you too can talk to anyone with confidence and smile with a fresh breath.
