Bad breath is a complaint that directly affects a person’s social life but is often something people are reluctant to talk about. Temporary relief is provided with masking products; however, as long as the source is not found, the problem continues. In the complaint of bad breath, the right approach lies in identifying the cause. As DijiDent Oral and Dental Health Polyclinic, in Türkiye we address this complaint with a detailed evaluation.
How Does Odor Form?
Most bad breath comes from volatile sulfur compounds released as a result of bacteria in the mouth breaking down protein residues. These bacteria multiply in areas with little oxygen that are not cleaned. Therefore, odor is mostly an indicator of a hygiene or tissue problem.
Causes Inside the Mouth
- The back of the tongue: It is the most common source. Build-up forms in the grooves at the back of the tongue.
- Gum disease: Periodontal pockets provide a sheltered environment for bacteria.
- Caries: Especially deep cavities that cannot be cleaned.
- Inadequate oral care: Interdental surfaces not being cleaned.
- Ill-fitting restorations: Overhanging margins and areas under bridges.
- Dentures: Denture surfaces that are not cleaned.
- Dry mouth: The reduced cleansing effect of saliva.
- Tonsil stones: Formations that accumulate in the crypts of the tonsils.
The Importance of Tongue Cleaning
This is the most neglected step. The surface on the back of the tongue offers a large area for bacteria and cell debris. Studies report that a significant proportion of mouth-related odors originate from this area.
A tongue brush or tongue scraper can be used for cleaning. It is recommended that it be applied with gentle movements from back to front, without triggering the gag reflex. This simple step makes a noticeable difference in many patients.
Dry Mouth
Saliva is the mouth’s natural cleanser. When it decreases, bacteria multiply more easily. This is also why the odor is more pronounced in the morning: saliva flow decreases during sleep.
Persistent dry mouth may be associated with some medications (some blood pressure, depression, allergy and urinary tract medications), some systemic diseases, mouth breathing and insufficient fluid intake. Do not stop your medications on your own decision; however, inform your dentist.
Causes Outside the Mouth
Most odors originate in the mouth; however, not all of them. Sinusitis and postnasal drip, tonsil problems, some respiratory diseases, advanced digestive system disorders and some metabolic conditions can also cause odor.
A common misconception needs to be corrected here: the belief that bad breath comes from the stomach is very widespread; yet the passage between the stomach and the mouth is normally closed and odor originating from the stomach is not as common as thought. There may be a contribution in conditions such as reflux; however, causes inside the mouth should be ruled out first.
Evaluation and Treatment
The path followed at our clinic is this: a detailed intraoral examination, periodontal measurements, tongue evaluation, examination of restorations and dentures, and questioning about dry mouth and medication history.
Treatment is directed at the source: professional cleaning and, if necessary, periodontal treatment, caries treatment, correction of ill-fitting restorations, establishing a tongue-cleaning habit and recommendations for dry mouth. If the complaint persists even though the causes inside the mouth have been eliminated, a referral is made to the relevant specialists.
Measurement Methods
Different methods can be used in the clinic to evaluate bad breath. The dentist’s direct evaluation is the most common approach; there are also devices that measure volatile sulfur compounds. These measurements make it possible to compare before and after treatment. In addition, some patients may perceive an odor even though there is actually none; distinguishing this situation is also part of the evaluation.
Are Mouthwashes Enough?
No. Antiseptic mouthwashes can provide temporary support and can be used on a dentist’s recommendation in certain periods. However, they do not eliminate the source. With long-term use, some products can cause surface staining and changes in taste perception. Mints and gum only mask it.
Frequently Asked Questions
