What Causes Bad Breath and How to Stop It: Dentist-Approved Solutions
Bad breath happens to everyone from time to time, but when it becomes persistent, it may be a sign of an underlying oral health issue. At Ballard Family Dentistry, we believe that understanding the cause of bad breath is the first step to finding a lasting solution.
In this guide, our dental team explains the most common causes of bad breath, what you can do to prevent it, and when to seek professional care.
What Causes Bad Breath?
Occasional bad breath can result from strong foods like garlic, coffee, or onions—but when it lingers, there’s usually more going on beneath the surface.
Here are the most common causes:
-
Poor Oral Hygiene
When plaque and food particles aren’t properly removed, bacteria break them down, releasing unpleasant odors. Brushing twice daily and flossing are your best defenses. -
Dry Mouth (Xerostomia)
Saliva naturally cleans your mouth and neutralizes odor-causing acids. A lack of saliva, often from dehydration, certain medications, or mouth breathing, can lead to chronic bad breath. -
Gum Disease
Bad breath is one of the earliest signs of gum disease. When bacteria collect along the gum line, they can cause inflammation, bleeding, and persistent odor. -
Diet and Lifestyle Habits
Tobacco products, alcohol, and certain diets (like high-protein or low-carb plans) can alter your mouth’s chemistry and cause noticeable breath odor. -
Medical Conditions
In some cases, sinus infections, tonsil stones, acid reflux, or diabetes can contribute to halitosis. If you maintain good oral hygiene but still have bad breath, it’s worth discussing with your dentist or physician.
How to Prevent and Treat Bad Breath
Fresh breath starts with consistent oral care and healthy daily habits. Here’s what you can do to manage or prevent bad breath:
-
Brush and Floss Regularly
Brush your teeth for two minutes, twice a day, and floss daily to remove odor-causing bacteria. Don’t forget to brush your tongue—it harbors bacteria that can lead to unpleasant smells. -
Stay Hydrated
Drink plenty of water to maintain saliva flow and wash away food particles. Chewing sugar-free gum can also help stimulate saliva production. -
Use Mouthwash Wisely
Choose an alcohol-free antibacterial mouthwash. It freshens breath while reducing bacteria, but remember—it’s a supplement, not a substitute for brushing and flossing. -
Eat a Balanced Diet
Crunchy fruits and vegetables like apples, carrots, and celery help naturally clean your teeth and promote saliva flow. Limit sugary snacks, which feed bacteria. -
Schedule Regular Dental Visits
Professional cleanings remove plaque buildup that brushing can’t reach. During your visit, your dentist can check for signs of gum disease or other causes of halitosis.
When to See Your Dentist
If you’ve tried improving your hygiene routine but still experience bad breath, it may be time for a professional evaluation. Persistent halitosis can be a sign of gum disease, infection, or other dental concerns that require treatment.
