6 Causes of Bad Breath (And How a Dentist Can Help You Fix It)

Bad breathe, also known as halitosis—can be more than just embarrassing. It might be a sign that something more serious is going on with your oral or overall health.

At Smile Dental in Stafford, TX, we treat patients every week who are frustrated with chronic bad breathe. The good news? Most cases are treatable, especially when diagnosed early.

Let’s explore the top causes of bad breath and how your dentist can help you get fresh breath and your confidence back.


1. Poor Oral Hygiene

The most common cause of bad breath is simple: not cleaning your mouth well enough. Food particles left behind feed bacteria, which produce foul-smelling sulfur compounds. If you’re not brushing and flossing thoroughly, plaque builds up, especially around your gums and tongue.

Fix:

  • Brush twice a day (especially before bed)
  • Floss daily
  • Clean your tongue using a scraper or soft toothbrush
  • Get regular dental cleanings

2. Diet

Foods like garlic, onions, coffee, and dairy can cause temporary bad breath. But a low-carb or high-protein diet can also lead to “ketone breath,” which has a metallic or fruity smell.

Fix:

  • Rinse your mouth after meals
  • Drink water throughout the day
  • Consider adjusting your diet if bad breath is persistent

3. Dry Mouth (Xerostomia)

Saliva helps wash away bacteria and food particles. If your mouth is too dry (due to medication, mouth breathing, or dehydration), bad breath can quickly follow.

Fix:

  • Drink plenty of water
  • Chew sugar-free gum to stimulate saliva
  • Ask your dentist about artificial saliva options

4. Gum Disease (Periodontitis)

Chronic bad breath may be a warning sign of gum disease, where bacteria infect the gums and cause inflammation, bleeding, and odor.

Symptoms include:

  • Red or swollen gums
  • Bleeding while brushing
  • Loose teeth

Fix:

  • Professional dental cleaning or deep scaling
  • Possible antibiotic rinses or root planing
  • Consistent home care afterward

5. Sinus or Throat Infections

Sometimes, bad breath doesn’t start in your mouth—it starts in your sinuses or throat. Mucus buildup, tonsil stones, or post-nasal drip can all contribute to unpleasant odors.

Fix:

  • Treat underlying sinus or throat issues
  • Stay hydrated
  • See a dentist or ENT for persistent cases

6. Medical Conditions

Conditions like diabetes, acid reflux, liver or kidney disease can cause systemic bad breath. This type of breath may smell fruity, metallic, or ammonia-like.

Fix:

  • Schedule a check-up with your primary care physician
  • Inform your dentist of any changes in health or medication
