1. Dry Mouth (Xerostomia)
Ever wake up with a mouth that feels like sandpaper? Dry mouth occurs when there’s not enough saliva to wash away food particles and bacteria. This creates the perfect environment for odor-causing bacteria to thrive. It also increases chances of dental decay, makes it hard to swallow food and even speak.
What causes dry mouth?
Dehydration
Certain medications (like antihistamines or antidepressants)
Chemotherapy
Mouth breathing, especially during sleep
How to fix it:
Drink plenty of water throughout the day.
Chew sugar-free gum to stimulate saliva production.
Consider a humidifier in your bedroom if you’re a mouth breather at night.
Discuss solutions like Biotene or perscription for Pilocarpine
Personal Note: I had a patient who was embarrassed by her bad breath despite brushing regularly. It turned out she wasn’t drinking enough water during the day. Once she improved her hydration, her breath improved dramatically!
2. Certain Foods
Garlic, onions, and spices are notorious for causing bad breath, but the issue goes deeper. These foods release sulfur compounds that linger in your mouth and bloodstream, returning through your lungs even after brushing. Also, keep in mind that certain foods or beverages carry an after taste.
How to fix it:
Brush and floss after meals.
Use a tongue scraper to remove residue from your tongue. May be hard to get used to them at first, start with small parts of the tongue at a time.
Chew parsley or drink green tea, both known for neutralizing odors.
3. Poor Oral Hygiene
Neglecting your brushing and flossing routine leads to plaque buildup, which harbors odor-causing bacteria. Food particles stuck between teeth are a common culprit.
How to fix it:
Brush twice daily for at least two minutes each time.
Floss once a day—don’t skip it! (Hard to build up to it, start with once a week)
Use an antibacterial mouthwash to kill odor-causing bacteria that can be prescribed through your dentist like Peridex.
4. Tongue Coating
Your tongue is like a sponge, trapping bacteria and food particles. If you’re not cleaning it, you’re leaving a major source of bad breath untreated.
How to fix it:
Use a tongue scraper daily (or your toothbrush if you don’t have one).
Pay attention to the back of your tongue, where bacteria often accumulate.
Personal Note: Tongue scrapers can be a challenge to use. Start with small portions of the tongue to avoid the gagging feeling.
5. Gum Disease (Periodontitis)
Bad breath can be an early warning sign of gum disease. When bacteria infect your gums, they release foul-smelling toxins. Left untreated, gum disease can lead to tooth loss or systemic health issues.
How to fix it:
Visit your dentist for a professional cleaning and gum assessment.
Follow a strict oral hygiene routine at home.
Personal Note: Periodontitis has no definite cure. It requires lifetime treatment to prevent it from getting worse and maintaining the issue is vital.
6. Tonsil Stones
Tonsil stones are small, hardened deposits of debris and bacteria that form in the crevices of your tonsils. They’re often a hidden cause of bad breath that many people overlook.
How to fix it:
Gargle with salt water to dislodge stones.
For persistent issues, consult a dentist or ENT specialist.
7. Acid Reflux (GERD)
When stomach acids travel up your esophagus, they can bring unpleasant odors with them. Acid reflux can also damage your teeth, compounding oral health issues.
How to fix it:
Avoid trigger foods like spicy dishes, coffee, and chocolate.
Eat smaller meals and avoid lying down after eating.
Consult a doctor for medication or further evaluation.
8. Unclean Dental Appliances
If you wear dentures, retainers, or mouthguards, they need just as much attention as your teeth. Failing to clean them regularly allows bacteria and odor to accumulate.
How to fix it:
Clean your appliances daily with a specialized cleaner.
Store them in a clean, dry container when not in use.
Put a few drops of your mouthwash on them to improve smell and taste when you put them on at night time.
9. Smoking and Tobacco Use
Smoking leaves a strong, lingering odor that’s hard to mask. It also dries out your mouth, exacerbating bad breath.
How to fix it:
Of course consider to quit smoking—it’s the best thing you can do for your breath and overall health.
Use a dentist-recommended mouthwash to combat odors as you work toward quitting.
10. Underlying Medical Conditions
Certain health issues, like diabetes, sinus infections, and kidney disease, can contribute to bad breath. For example, a fruity odor in the breath is a hallmark of uncontrolled diabetes.
How to fix it:
Consult a doctor for proper diagnosis and treatment.
Share your symptoms with both your dentist and physician for a comprehensive approach.
Personal Note: I have this issue in the winter time when my sinuses give me issues and have a consistent post nasal drip that gives me the bad odor. I use a saline rinse to clean my sinuses.
