Do You Have Bad Breath? Here’s What Might Be Causing It

Are you struggling with bad breath? Here’s what might be the cause and what you can do to fix it. Contact us to get fresh breath today.

We’ve all had that moment—cupping a hand over the mouth, checking our breath, and wondering, “Is it me?” Bad breath, or halitosis, can be more than just a social inconvenience. It’s often a sign of underlying oral or medical issues, and for many people, it can seriously damage confidence and relationships.

At The Dental Anesthesia Center in St. Louis, we help patients address the root causes of chronic bad breath—often with simple solutions and, when needed, comfortable care options like sedation for those who are nervous about visiting the dentist.

I have NEVER had a positive experience with dentist…until now!! I was mind blown how kind the staff was, not just to me but to everyone! I have debilitating anxiety when it comes to dentists because of bad previous experiences, so I was very nervous. But, all the staff, including Dr. Thom, were very gentle, kind, and understanding. They took time to listen to all my concerns and address them, helping to put me at ease. I was also amazed how professional the whole office ran and how completely reliable they were. They easily guided me through the process and everything went so smoothly, including my sedation. I have never been treated so kindly by any dental office before, I was struggling to believe I wasn’t in some kind of dream. But. They really were that nice.

My recovery from sedation and all
The dental work they did to save my tooth was amazing, not a single issue! Dr. Thom even called personally to check on me a day later.

Coming back to put my permanent crown in was the same experience. They were all so kind,
Good about explaining everything they were doing and make the experience light and dare I say…fun.

I would drive 2.5 hours again in a heartbeat to do my work here. Best dental experience I’ve ever
had hands down!!!!!!! Thank you Dr. Thom for giving my life and tooth back. I’m so excited to not be in so much excruciating pain anymore!

What Exactly Is Halitosis?

Halitosis is persistent bad breath that doesn’t go away with brushing, mouthwash, or mints. While almost everyone experiences temporary bad breath (especially in the morning or after garlic-heavy meals), chronic halitosis typically signals a deeper issue.

Common Causes of Bad Breath

1. Poor Oral Hygiene

  • The most common culprit. When food particles and bacteria build up around the teeth, tongue, and gums, they release foul-smelling compounds.
  • If you skip flossing, you’re leaving about 35% of your tooth surface uncleaned.

2. Gum Disease

  • Gingivitis and periodontitis harbor anaerobic bacteria that produce sulfur compounds—the “rotten egg” smell.
  • Bleeding gums can also create an environment where bacteria thrive.

3. Dry Mouth

  • Saliva helps cleanse the mouth and neutralize acids. A dry mouth allows bacteria to grow unchecked.
  • Common in people taking medications, those who mouth-breathe, or anyone with salivary gland issues.

4. Dietary Triggers

  • Garlic, onions, coffee, and alcohol are known offenders.
  • High-protein, low-carb diets can also create ketone breath—a strong, chemical smell.

5. Smoking or Tobacco Use

  • Tobacco products leave a distinctive odor and dry out the mouth, increasing bacteria.
  • Smokers are also more likely to have gum disease, compounding the problem.

6. Tonsil Stones

  • Small, calcified deposits that form in the tonsils and trap bacteria and debris.
  • Often produce a strong, foul odor when disturbed.

7. Underlying Medical Conditions

  • Bad breath may indicate:
    • Sinus infections
    • Acid reflux (GERD)
    • Diabetes (sweet or fruity breath)
    • Liver or kidney issues

If you’ve ruled out oral causes and still have persistent bad breath, it’s worth consulting a physician.

How to Get Rid of Bad Breath

How Is Bad Breath Diagnosed?

At The Dental Anesthesia Center, we conduct a comprehensive evaluation that may include:

  • Review of medical and dental history
  • Examination of gums, teeth, and tongue
  • Measuring pocket depths to assess for gum disease
  • Identifying signs of dry mouth or oral infections

For patients who feel anxious or embarrassed about this discussion, we offer sedation options to make your visit as stress-free as possible.

How to Get Rid of Bad Breath

1. Upgrade Your Daily Hygiene Routine

  • Brush twice a day with fluoride toothpaste
  • Floss daily to remove hidden food particles
  • Don’t forget to brush your tongue—a major source of odor-causing bacteria

2. Stay Hydrated

  • Drink water regularly to stimulate saliva
  • Avoid sugary or acidic beverages that contribute to dry mouth

3. Quit Tobacco

  • One of the most powerful ways to improve both your breath and overall health

4. Use Antimicrobial Mouth Rinses

  • Look for rinses that kill bacteria, not just mask odor
  • Avoid alcohol-based rinses if dry mouth is an issue

5. Treat Gum Disease

  • Professional cleanings
  • Scaling and root planing (deep cleaning)
  • Ongoing periodontal maintenance

6. Address Dental Issues

  • Repair cavities or cracked fillings
  • Remove impacted food or treat infections
