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 cannot say enough wonderful things about The Dental Anesthesia Center and Dr. Thoms. My 7-year-old, who has autism, recently had dental work done here and the experience exceeded expectations. The staff was incredibly kind, patient, and understanding of his needs. They took the time to make him and us feel comfortable, never rushed, and explained everything. I am so grateful for this office and the team that made my son's dental care possible. I would recommend The Dental Anesthesia Center and Dr Thoms to any parent, especially those with children who have special needs. They truly go above and beyond. ❤️
Response from the owner:Thank you so much for your thoughtful review and kind words! We’re truly grateful for your trust in our team and Dr. Thoms. Knowing your visit was a positive and comfortable experience means the world to us — it’s exactly what we strive for with every patient and family. 💙
Very patient with elderly patients. Very good experience.
Response from the owner:Thank you for sharing your feedback! We’re pleased to know the visit was a positive experience.
My son has been a patient of Dr Michael Hoffman since he was 5 years old. He is now 21 years old. My son has diagnosis of autism spectrum disorder and therefore I am cautious of who I select as a treatment provider. Dr. Hoffman’s office is professional, kind and I know they have his best interest at heart. I highly recommend Dr. Hoffman and staff to anyone seeking dental care.
Response from the owner:Thank you for your kind words and recommendation! We truly appreciate your trust in our team over the years.
Super experience. Gentle and empathetic. All round care is great. Staff are wonderful.
Response from the owner:Thank you for your kind review! We’re so glad you had a great experience with our team.
We are forever grateful for Dr Hoffman and his wonderful staff for having the vision of how to get necessary dental work done for patients who are dealing with autism and cannot tolerate it without dental anesthesia. We have been taking our adult daughter there once a year for the last four years. Thanks to Dr Hoffman’s vast knowledge and expertise, our daughter has been able to get wisdom teeth removed, cavities filled, teeth cleaned and detailed X-rays to know exactly what needed done. The Dental Anesthesia Center is a great service to the community. Thank you so much for helping us.
Response from the owner:hank you so much for your thoughtful review and kind words about our team! We truly appreciate your trust in us and are honored to provide care in a way that helps make dental treatment more comfortable and accessible for all patients. Your feedback means a great deal to our entire staff.

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
