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.

Yes, my grandson has nonverbal autism and they took very good care of him.. He had to have some extra extractions which I was concerned about, but everything went very well. Very happy and I thank you all for all the work you did.
Response from the owner:Thank you for your kind words. We’re so glad to hear you had a positive experience and that everything went smoothly. We truly appreciate your trust in us.
I took my son to an appointment today with Dr. Hoffman. We had a great experience from the time we arrived until we departed. The receptionist was very friendly and helpful. The dental assistants were very helpful and polite with my son. The doctor is very kind and patient. They explain everything as we went through the process. We were aware of the cost from the beginning to the end and we're allowed to make decisions about how to handle my child's care and not shocked with additional charges after the fact. My child does not resist going to this office. Great experience.
Response from the owner:Thank you for your kind words! We’re so glad to hear your experience was positive from start to finish. Our team works hard to create a comfortable, transparent, and supportive environment for every patient and family. We truly appreciate you taking the time to share your feedback!
Always nice and professional doctors and staff! Highly recommend especially if you have dental anxiety!
Response from the owner:Thank you for your kind words! We’re so glad you felt comfortable with our team. We truly appreciate your recommendation!
Dr. Thoms and everyone of his staff members are incredible. I was warmly welcomed and made to feel comfortable and relaxed. Which is saying something as I had not been to the dentist in years due to fear/anxiety.
My procedure was clearly explained. The office staff was beyond helpful with payment and insurance.
The day of my appt was exactly as planned. We started ahead of schedule! The technicians and assistants were clearly skilled and again, helped ease my nervousness. We finished all work as planned. And then Dr. Thoms sat with me and my husband to discuss “everything.” He is very thorough. And finally one of his staff wheeled me down to the elevator, out across the parking lot, and helped me into my van. Now that is service!
Around 8:30 p.m. my cell phone rang and it was Dr. Thoms calling to check up on me. Wow!!!!! This man has all you could want in a dentist—kind, compassionate, thorough, understanding, excellent communicator, and skilled.
I cannot come up with the best words to so highly recommend the Dental Anesthesia Center. It was a remarkable, yet simple, but thorough experience for me.
If you are putting off going to the dentist and have anxiety or fears please call them. They will gently and competently take care of you.
And no, this is not an advertisement/ commercial—I am a real live (satisfied) patient.
Response from the owner:Thank you so much for your kind and thoughtful review! We’re honored to hear that you felt welcomed, comfortable, and well cared for throughout your experience. Our team is dedicated to providing compassionate, thorough care—especially for those who may feel anxious about dental visits—so it means a lot to know that came through. We truly appreciate your recommendation and are grateful you chose us for your care.
The practice is top notch. Could not ask for better care.
Response from the owner:Thank you for your kind words! We’re grateful for your feedback and are proud to provide high-quality care in a supportive environment.

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 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
