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.

This dental practice is excellent with my daughter (25 y/o with autism). The entire team is kind, patient, and understanding. They take time to explain what will be happening and only recommend procedures that are truly necessary.

The staff never rushes and makes patients feel comfortable and supported. They are very in tune with sensory challenges. It’s clear they care deeply about creating a positive experience and treating everyone with dignity.

We heartily recommend Dr. Hoffmann and his team.
Response from the owner:Thank you so much for your kind words! We’re thrilled to hear your daughter feels comfortable and supported. Dr. Hoffmann and our team truly appreciate your recommendation.
Best decision I ever made was coming here. Highly recommend. The front office is great, Lena is awesome and docs are so good. Plus you get sweet glasses while they work 😎
Dr. Thom and the entire staff at the Dental Anesthesia Center were warm, friendly and welcoming to me and my husband. My husband has dementia and needed extensive dental work. Dr. Thom took the time to explain to me what needed to be done before the procedure began. My husband is now fully recovered and doing just fine. I'm so grateful that we were referred to the Dental Anesthesia Center. Thank you!!

The Dental Anesthesia Center (DAC) is awesome. When I started there 19 years ago my dental health had deteriorated and my fears were intense. Their expertise and compassion got me back on the right dental track. I still get nervous - but things are so much better now in terms of my dental and gum health.. Don't lose hope - try the DAC!

My appointment today was for a cleaning - and a standard check of gum health etc. Carrie - as always - did EXCELLENT work. She is very kind and thorough and knowledgeable .. and patiently answers all my questions. Carrie is positive and supportive with us patients ... and provides guidance on better at-home care for our teeth and gums.

My thanks also to the office staff who are very helpful with questions or concerns.
Response from the owner:Thank you for your continued trust and kind words! We're honored to have be part of your journey. It means so much to know we've made a lasting impact—your story is truly inspiring!

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
