Have you ever noticed that your breath smells bad even after brushing your teeth?

You may think the problem is simply from the food you ate, but persistent mouth odour can have several causes.

Mouth odour, medically called halitosis, is an unpleasant smell coming from the mouth. It can be temporary, such as after eating garlic or onion, or it can persist because of an underlying oral or medical problem.

Common causes of mouth odour include:

1. Poor oral hygiene: Food particles and bacteria can remain between the teeth, around the gums and on the tongue. These bacteria can produce unpleasant-smelling compounds.

2. Tongue coating: The tongue can collect bacteria, dead cells and food debris, especially toward the back of the tongue. This is one reason why cleaning the tongue is important.

3. Gum disease: Bleeding, swollen or infected gums can contribute significantly to persistent bad breath.

4. Dry mouth: Saliva helps clean the mouth and control bacteria. When saliva production decreases, mouth odour can become more noticeable.
 This can happen with dehydration, sleeping with the mouth open, certain medications or some medical conditions.

5. Certain foods: Garlic, onions and some strongly flavoured foods can temporarily affect breath.

6.Smoking and alcohol: Smoking can contribute to persistent mouth odour, while alcohol can contribute to dry mouth.

7.Dental problems: Untreated cavities, infections and poorly cleaned dentures or dental appliances can contribute to bad breath.


What can you do to prevent mouth odour?

• Brush your teeth twice daily with fluoride toothpaste.
• Clean your tongue gently every day.
• Clean between your teeth with floss or another appropriate interdental cleaner.
• Drink enough fluids throughout the day.
• Avoid smoking.
• Don't rely on chewing gum or mouthwash to permanently cover the smell.
• Visit a dentist if the problem persists.


And what about your diet?

Your diet can influence your breath, but there is no special food that permanently "cures" mouth odour.

Try to maintain a balanced diet containing vegetables, fruits, whole grains and adequate protein.

Foods with high water content, such as cucumber, watermelon and oranges, can also contribute to overall hydration.

Crunchy fruits and vegetables may help mechanically stimulate saliva while chewing, but they should not replace proper brushing and dental care.

Also pay attention to foods that seem to trigger odour for you. Garlic and onions, for example, can temporarily affect breath.

One important point:

If your mouth odour continues even though you maintain good oral hygiene, don't simply keep buying breath mints.

Persistent bad breath can sometimes be a sign of gum disease, dental infection, dry mouth or another underlying condition.

Start with a dental check-up, especially if you also have bleeding gums, tooth pain, loose teeth, mouth sores or a persistent unpleasant taste.

Your breath can sometimes tell you something about your health.
