Bad Breath (Halitosis) Treatment
An approach that identifies the source correctly and treats the cause
Provided at our clinic in Altunizade, Üsküdar (Istanbul).
IN SHORT
Bad breath (halitosis) is the general name for the unwanted odours felt in the breath, and it most often arises from causes inside the mouth. The odour comes from the volatile sulphur compounds produced by the bacteria that accumulate on the back of the tongue and in the gum pockets. The source of the odour is not always the mouth; in conditions related to the sinuses, the digestive system or systemic diseases, dental treatment alone is not enough and referral to the relevant doctor is needed.
What causes bad breath?
The most common cause of bad breath is the volatile sulphur compounds released by the bacteria in the mouth as they break down protein residues. These bacteria accumulate most densely on the back of the tongue, between the teeth and in inflamed gum pockets.
Gum disease, untreated cavities, ill-fitting dentures and dry mouth are the main oral factors that increase the odour. The temporary odour that occurs in the morning is a normal situation caused by the reduced flow of saliva during the night, and it usually passes with morning care.
Who needs an assessment?
Persistent bad breath is most often due to a correctable cause, and having it assessed is advised. Especially in people who complain of bleeding gums, suspected cavities or dry mouth, an examination can reveal both the source of the odour and an underlying gum problem.
Some people with bad breath think they smell constantly even though they have no noticeable odour, while others are not aware of their odour. For this reason, in the assessment the objective examination findings are as important as the person's complaint. Identifying the source correctly prevents unnecessary product use and wrong guidance.
Situations in which dental treatment is not enough
If the odour continues even though the oral causes have been resolved, the source is most likely outside the mouth. In this case, instead of insistently continuing dental treatment, referral to the relevant doctor is needed. The following situations suggest a systemic cause:
Odour accompanied by nasal congestion, post-nasal drip or frequent sinusitis (an ear, nose and throat assessment may be needed).
Odour accompanied by heartburn, acid regurgitation or reflux complaints.
A distinctive breath odour that can appear in conditions such as uncontrolled diabetes, kidney or liver disease.
Making this distinction honestly ensures that the patient receives the right treatment in the right place and at the right time.
How does the treatment progress step by step?
Examination and identifying the source
The teeth, gums and tongue are assessed; whether the odour is due to an oral cause is investigated.
Dental scaling and gum treatment
Inflamed gums and deposits are the most common oral source of the odour and are addressed first.
Resolving cavity- and denture-related causes
Untreated cavities and ill-fitting dentures are corrected.
Tongue care
The appropriate technique for regularly cleaning the biofilm on the back of the tongue is explained.
Management of dry mouth
The causes that reduce saliva flow are assessed and recommendations are given.
Referral in cases judged necessary
If no oral cause is found, referral to the relevant medical branch is made.
Daily care and control of the odour
The most effective approach in controlling odour of oral origin is the regular cleaning of the teeth and especially the back of the tongue, interdental cleaning and the prevention of dry mouth through adequate fluid intake. This care makes the result obtained with treatment lasting.
The temporary odour felt in the mornings and the persistent odour that continues throughout the day are different from each other. Morning odour is a normal situation caused by the reduced flow of saliva during the night and passes with morning care. Odour that continues throughout the day and persists despite care, however, is a situation that needs to be assessed.
Dry mouth is a frequently overlooked cause of odour. Some medications, breathing through the mouth and inadequate fluid intake reduce saliva flow and upset the bacterial balance. For this reason, the management of dry mouth holds an important place in controlling the odour.
Risks and common mistakes
Bad breath itself is not a medical procedure; what really matters is preventing the cause from being masked by wrong approaches.
Mint sprays, gum and mints only mask the odour temporarily; they do not treat the cause and do not provide a lasting solution.
Continuous and high-intensity use of antiseptic mouthwash can upset the oral flora and the saliva balance, increasing dry mouth and indirectly the odour; its use should be determined under the dentist's recommendation.
Trying to suppress persistent odour with products alone can allow an underlying problem such as gum disease to progress.
Oral and extra-oral causes
The first step in treating bad breath is to determine whether the source is inside or outside the mouth, because the treatment depends entirely on this distinction. While dental treatments give results in oral causes, referral to the relevant medical branch is needed in extra-oral causes. The table below compares the two sources.
Compare the options
| Oral-origin halitosis | Extra-oral (systemic) halitosis | |
|---|---|---|
| Common causes | Tongue biofilm, gum disease, cavities, dry mouth | Sinusitis/post-nasal drip, reflux, some systemic diseases |
| Course of the odour | Decreases noticeably with oral care | Persists despite oral care |
| Where it is resolved | Dental treatments | The relevant medical branch (ENT, internal medicine, etc.) |
| Role of the dentist | Carries out the treatment directly | Rules out the oral cause and refers the patient |
Which option is suitable is decided together after an intraoral examination.
Frequently Asked Questions
Most of the odour is of oral origin; the most common causes are the bacterial build-up on the back of the tongue, gum disease and untreated cavities.
These products mask the odour for a short time but do not remove the cause. For a lasting result, the source of the odour needs to be treated.
If the odour continues even though the oral causes have been resolved, the source is most likely outside the mouth. A sinus, reflux or systemic condition may be involved, and referral to the relevant doctor is needed.
Yes. The back of the tongue is the area where odour-causing bacteria accumulate most densely; regular tongue cleaning is effective in controlling odour of oral origin.
