Reader Question: No matter how much I brush and floss, I always seem to have bad breath. What could be causing this, and how can I get rid of it?

Persistent bad breath, also known as halitosis, can be frustrating, especially if it happens even when you brush and floss regularly.

Many factors can contribute to bad breath, which often starts in the mouth. Bacteria naturally build up on your teeth, gums, and tongue, and some of these bacteria produce unpleasant odors. Gum disease and cavities can also hold onto these bacteria.

Here are some common causes of bad breath originating in the mouth:

  • Bacteria buildup — This is the most common culprit, and these bacteria produce sulfur compounds that cause unpleasant odors.
  • Gum disease and cavities — These conditions create pockets where food particles and bacteria can get trapped, leading to bad breath.
  • Dry mouth (xerostomia) — A lack of saliva can lead to an increase in bacteria, as saliva helps cleanse the mouth by removing food particles and debris.
  • Tonsil stones — These are calcified deposits that form in the crevices of the tonsils and can cause bad breath.

Sometimes, the culprit isn’t in your mouth. Dry mouth, which can be caused by certain medications or medical conditions, can lead to bad breath because saliva helps wash away food particles and bacteria. Even some health problems, like GERD or sinus infections, can cause bad breath.

Diet can also play a role. Foods like onions and garlic have strong odors, and some of those odors can travel through your bloodstream to your lungs and come out in your breath. Coffee and sugary foods can also contribute to bad breath.

What can you do about persistent bad breath?

There are things you can do to manage bad breath. Here’s a routine you can follow for fresher breath:

  • Brush your teeth twice daily with fluoride toothpaste for at least two minutes.
  • Floss daily to remove food particles and plaque between your teeth.
  • Clean your tongue with a scraper or brush to remove bacteria that can cause bad breath.
  • Stay hydrated by drinking plenty of water throughout the day.

What diet adjustments can you make for fresh breath?

Consider limiting your intake of foods known to cause bad breath, like onions and garlic. Probiotic foods, like yogurt, can help reduce bad bacteria in your mouth.

Some people find natural remedies like chewing fennel seeds or drinking pineapple juice helpful for freshening breath. However, it’s important to consult your doctor before trying any new supplements.

When should you see a dentist for bad breath?

If you’ve tried these tips and your bad breath persists, don’t hesitate to see your dentist. They can help identify any underlying medical conditions and recommend treatments specific to your situation.

There are also special mouthwash and toothpaste designed to combat bad breath that your dentist might recommend.

Remember, there are effective ways to deal with persistent bad breath. With a little effort and the right guidance, you can achieve fresh breath and regain your confidence.
