Here are some tips.
1. Don’t use conventional breath mints.
Sugar makes bad breath even worse. That’s the problem with conventional breath mints; they’re all sugar! And all bacteria grow in sugar; they love it! So when that mint taste goes away after 5 minutes, what does your breath actually smell like? Hmm…
Even worse are those ones that you swallow. Bad breath definitely does not come from the stomach!
Taste is not what determines fresh breath. Oxygen is what really matters.
Dr. Katz says, “The breath-freshening power of my gum lasts long after the taste runs out – this is because the taste is not what is responsible for the breath control.”
2. Use baking soda.
Dr. Katz says, “If you are having trouble with a metallic or sour/bitter taste, sprinkle some baking soda on the bristles of your toothbrush, then apply toothpaste and brush. The baking soda helps neutralize any excess acids in your mouth.”
Don’t forget to brush your tongue!
3. Switch to TheraBreath toothpaste.
Sodium Lauryl Sulfate, otherwise known as soap, is a common ingredient in common toothpastes. In many studies, it has been linked to the production of canker sores because it irritates your oral mucosa. Play it safe and switch over to the good stuff.
4. Drink water.
As simple as it sounds, drinking lots of water is very helpful in the prevention of bad breath. A dry mouth easily harbors bacteria which leads to bad breath, so be sure to consistently drink enough water to keep your mouth moist.
5. Drink a cup of green tea a day.
Researchers at the Chicago College of Dentistry found that polyphenols, which are found in green tea, inhibit the growth of an odor-causing bacteria by 30%. Green tea is full of antioxidants and other good stuff so you should drink it even if you’re not worried about bad breath.
6. Quit smoking (or don’t start).
Smoking is horrible for your breath, and let’s not forget the rest of your body.
7. Breath through your nose.
The simple act of breathing through your nose instead of your mouth will reduce the chances of dry mouth, and therefore, will reduce the chance of bad breath.
