What should you eat and drink to keep your breath fresh for longer?

Diet is not a substitute for hygiene or treatment of the causes of bad breath, but it can affect saliva production, trapped debris and the intensity of odour after a meal. Water remains the most important drink for the mouth.

What supports fresher breath?

Water

Drinking water regularly helps limit dryness and rinse away some debris. Small amounts throughout the day are more helpful than a large amount only in the evening.

Crunchy vegetables

Carrots, cucumber and peppers require chewing and can stimulate saliva flow. However, they do not clean between the teeth in the same way as floss.

Foods that require chewing

Chewing increases saliva flow, so sugar-free gum may be helpful after a meal if there are no reasons for you to avoid it.

Regular meals

For some people, long periods without food or drink can increase dryness and a characteristic odour. This does not mean that you should snack constantly.

What can make odour worse?

• garlic and onions,
• alcohol,
• large amounts of coffee,
• smoking,
• very sweet snacks eaten frequently,
• strongly flavoured foods.

Some compounds from garlic or onions enter the bloodstream and are exhaled through the lungs, so brushing alone does not remove the smell immediately.

Mints, parsley and home remedies

They may temporarily change the perceived smell, but they do not remove coating, debris between the teeth or gum problems. Sugary mints are also not a good option when used frequently.

The most important plan for the whole day

1. Drink water regularly.
2. Rinse your mouth with water after meals.
3. Follow a complete hygiene routine morning and evening.
4. Clean your tongue and the spaces between your teeth every day.
5. Do not mask a persistent problem with food.

FAQ

Does an apple replace brushing?

No. It can stimulate saliva, but it does not remove dental plaque thoroughly.

Does lemon freshen the breath?

The sour taste can increase saliva flow, but frequent acid contact with enamel is not a good hygiene method.
