Bad breath: why the mouth is examined first

01 “It must be coming from my stomach” — is that true?

The cause is often actually in the mouth. As bacteria break down organic substances, they can produce compounds that cause odour. The tongue surface plays an important role. Inflamed gum pockets and other changes in the mouth may also be involved. A dental practice is therefore a sensible first point of contact for persistent bad breath.

It would, however, be equally inaccurate to rule out other causes in principle. Alongside tooth and gum problems, dry mouth or, less commonly, conditions outside the oral cavity may play a role. Examination matters, rather than prematurely attributing it to one organ. gesund.bund.de: Bad breath

02 What is discussed at the appointment?

The conversation includes questions about duration and progression, oral care, diet and medication. The mouth is then examined, including the teeth, gums and tongue coating. Treatment is based on what is actually found. gesund.bund.de: Bad breath

If no adequate explanation is found in the mouth, further medical assessment may be appropriate. A later review helps determine whether the agreed measures are sufficient. German Society of Periodontology: Bad breath

You can note three things: when is the odour noticeable? Did you notice it yourself, or did someone else? What have you already changed? This starts the conversation with specific observations. You do not need to diagnose yourself.

03 Four tips that fit into everyday life

1. Brush regularly: Brush twice a day with fluoride toothpaste and clean between your teeth daily using a suitable aid.
2. Clean your tongue gently: Gently clean the tongue surface once a day; vigorous scrubbing or injury is not the aim.
3. Do more than mask it: A fresh taste after using a product does not establish whether the cause has been addressed.
4. Have persistent symptoms assessed: If bad breath continues for several weeks despite careful care, or if your gums are painful or bleeding, a dental appointment is advisable. NHS: Bad Breath

This list offers guidance, not a suggestion to buy every available oral care product. Instead, note what you already use and bring outstanding questions to the appointment. A clear care plan should fit your everyday life and be chosen according to the findings.

Bad breath cannot be reliably assessed solely by how you perceive your own breath. If you are unsure, an objective examination is more helpful than repeatedly checking yourself. gesund.bund.de: Bad breath
