Bad Breath: Common Causes, How to Check & What to Do
Bad breath happens to everyone occasionally. Whether it’s morning breath, coffee, garlic or something you ate, an unpleasant smell is usually nothing to worry about.
But what if your bad breath doesn’t go away?
Persistent bad breath, also known as halitosis, can sometimes be a sign of an underlying oral health problem.
At Metral Dental in Nanaimo, we often remind patients that chronic bad breath isn’t always something that can be solved with mints or mouthwash. Plaque buildup, gum disease, tooth decay, dry mouth and other dental concerns can all contribute to unpleasant breath.
Understanding what’s causing the problem is the first step toward finding a lasting solution.
How Can You Tell if You Have Bad Breath?
One of the frustrating things about bad breath is that it can be surprisingly difficult to detect yourself. Our sense of smell naturally adapts to familiar odours, meaning we may not notice changes in our own breath.
Here are a few ways to check:
1. Ask someone you trust
It might feel a little awkward, but asking a partner, family member or close friend is often one of the most reliable ways to find out.
2. Try the floss test
Gently floss between your back teeth and check the floss for an unpleasant odour. This may reveal trapped food particles or bacterial buildup between teeth.
3. Check your tongue
Look at your tongue in the mirror. A white or yellowish coating can sometimes indicate a buildup of bacteria and debris that contribute to bad breath.
4. Pay attention to a persistent unpleasant taste
A bad taste in your mouth doesn’t necessarily mean you have bad breath, but it can accompany dental infections, gum disease or other oral health concerns.
5. Ask your dentist
If you’re concerned about persistent bad breath, your dentist can examine your teeth, gums and oral tissues for potential causes.
While home checks may provide clues, they aren’t always reliable. A dental examination is the best way to investigate possible oral health problems contributing to chronic bad breath.
What Causes Bad Breath?
There are several possible causes of bad breath, ranging from everyday habits to underlying dental or medical conditions.
1. Plaque and Bacteria Buildup
Your mouth naturally contains bacteria. When food particles and plaque accumulate around your teeth, gums and tongue, certain bacteria produce unpleasant-smelling compounds.
Brushing, flossing and cleaning your tongue can help reduce this buildup.
2. Gum Disease
Persistent bad breath can be an early warning sign of gum disease. Gingivitis and periodontitis develop when plaque and bacteria contribute to inflammation and infection of the tissues surrounding your teeth.
Other symptoms may include:
- Bleeding gums when brushing or flossing
- Red, swollen or tender gums
- Receding gums
- A persistent bad taste in your mouth
3. Tooth Decay and Dental Infections
Cavities, cracked fillings and dental abscesses can create areas where bacteria and food debris accumulate. In some cases, persistent bad breath may be accompanied by tooth sensitivity, pain, swelling or an unpleasant taste. Dental infections require professional assessment and treatment.
4. Dry Mouth
Saliva plays an important role in keeping your mouth clean. It helps wash away food particles, neutralize acids and control bacterial growth. When saliva production decreases, bacteria and debris can accumulate more easily.
Dry mouth can be caused by:
- Certain medications
- Dehydration
- Mouth breathing
- Smoking
- Some medical conditions
If you regularly experience dry mouth, mention it to your dentist.
5. Food, Drinks and Lifestyle Habits
Certain foods and beverages can temporarily affect your breath. Common examples include garlic, onions, coffee and alcohol. Smoking and other tobacco use can also contribute to persistent bad breath, dry mouth and gum disease.
6. Other Medical Conditions
Not all bad breath originates in the mouth. Sinus infections, tonsil stones, acid reflux and certain medical conditions can sometimes contribute to unpleasant breath. If a dental examination doesn’t identify an oral cause, your dentist may recommend speaking with your physician.
Six Ways to Improve Bad Breath
The good news is that many common causes of bad breath can be managed with consistent oral hygiene and healthy habits.
1. Brush Twice a Day
Brush your teeth thoroughly twice daily using fluoride toothpaste. Pay particular attention to the gumline, where plaque tends to accumulate. An electric toothbrush can be helpful, especially if it includes a timer to encourage brushing for the recommended two minutes.
2. Floss Every Day
Flossing removes plaque and trapped food particles from areas your toothbrush can’t easily reach. If you notice an unpleasant smell when flossing, it may indicate bacterial buildup between your teeth.
3. Clean Your Tongue
Your tongue can harbour bacteria, particularly toward the back. Gently brushing your tongue or using a tongue scraper can help remove debris and reduce odour.
4. Stay Hydrated
Drinking water throughout the day helps maintain saliva production and rinse away food particles. If you frequently experience dry mouth, try sipping water regularly and discuss persistent symptoms with your dentist.
5. Try Sugar-Free Gum
Chewing sugar-free gum can stimulate saliva production, helping to reduce dry mouth and temporarily improve breath. Look for gum containing xylitol, a sugar substitute that doesn’t contribute to tooth decay in the same way as regular sugar.
6. Keep Up With Regular Dental Visits
Professional dental cleanings remove plaque and tartar that can’t be eliminated through brushing and flossing alone. Regular dental examinations also help identify cavities, gum disease and other oral health concerns that may contribute to bad breath.
Does Mouthwash Help Bad Breath?
Mouthwash can temporarily improve breath, but it isn’t always a long-term solution. Some mouthwashes simply mask unpleasant odours, while others contain ingredients designed to reduce bacteria or neutralize odour-causing compounds. An alcohol-free mouthwash may be preferable for people experiencing dry mouth.
If you’re using mouthwash regularly but still experiencing bad breath, it’s worth investigating the underlying cause rather than relying on temporary fixes.Your dentist can recommend products appropriate for your oral health needs.
When Should You See a Dentist About Bad Breath?
Occasional bad breath after coffee, garlic or certain foods is completely normal.
Persistent bad breath, however, is worth mentioning to your dentist, particularly if improving your oral hygiene doesn’t seem to help.
You should also arrange a dental examination if you notice:
- Bleeding or swollen gums
- Persistent bad tastes
- Tooth pain or sensitivity
- Loose teeth
- Ongoing dry mouth
- Swelling or other signs of dental infection
A dental examination can help determine whether your bad breath is related to plaque buildup, gum disease, tooth decay or another oral health concern. If your dentist doesn’t find an oral cause, further medical assessment may be recommended.
