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 had an excellent experience with Dr. Behl and her entire team during my wisdom tooth extraction. I chose IV sedation, and it made all the difference. I was awake and aware throughout the procedure, but I felt completely relaxed and never experienced the panic or anxiety I usually have at the dentist. Dr. Behl and her staff were compassionate, professional, and attentive from start to finish, making sure I was comfortable every step of the way. If you have dental anxiety or avoid going to the dentist because of fear, I highly recommend Dr. Behl and her team. They provided exceptional care and made what I expected to be a stressful experience surprisingly calm and comfortable.

All of the staff have been extremely incredible. Dr. Thoms was amazing & really helped calm me before my procedure. Dr. Thoms answered any & all questions I have had & was extremely understanding when it comes to having dental anxiety. Robyn was the best X-ray technician I have ever had. She felt personable but still extremely professional. Throughout my life I have been to numerous dentists in hopes of finding one that will take my extreme dental anxiety seriously & not make me feel bad for it. I have finally found my favorite dentist. The Dental Anesthesia Center is my #1 pick if I had to chose any dentist.

I started seeing this practice as a scared middle age woman that thought she was quickly on the way to being toothless. Years later now, still working with the amazing Dr Behl and her amazing staff, I have been able to continue with my present teeth. Alway kind, full of grace, mercy and humor!
Response from the owner:Thank you for your thoughtful review. We’re honored to be part of your dental journey and appreciate your kind words about Dr. Behl and our team.
We have been taking our son to Dental Anesthesia since 2019. He gets his dental treatment and blood work done at the same time. We find the staff and Dr. Thoms highly professional. They communicate well and provide excellent treatment/services. Getting blood work done during sedation helps us a lot.
Response from the owner:Thank you for your kind words and for sharing your experience. We’re honored to be part of your family’s care. We appreciate your trust in us.

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
