Halitosis: hidden causes and effective solutions

Halitosis, also known as bad breath, is a common disorder and can have a significant impact on the social life and personal safety of sufferers. Although it is often associated with poor oral hygiene, there are numerous hidden causes that can contribute to bad breath. Adopting the right prevention strategies and identifying the triggers allows the problem to be solved effectively and lastingly.

In this article, we will look in detail at the causes of halitosis, the lesser-known factors that can trigger it, and the most effective remedies to counteract it permanently.

Halitosis causes: when the problem is more than just oral hygiene

Many people believe that bad breath depends solely on the lack of a proper cleaning of the mouth. However, although poor oral hygiene is among the most common causes, it is not the only one responsible for persistent halitosis.

The main causes of halitosis include:

• Accumulation of bacteria on the tongue: The tongue is one of the areas where more bacteria are deposited, especially in the back, contributing to the formation of volatile sulfur compounds, which are responsible for bad odor.
• Dryness of the mouth (xerostomia): Saliva plays a key role in cleaning the oral cavity. Reduced saliva production, due to dehydration, medications or salivary gland problems, can cause halitosis.
• Gum problems: Gingivitis and periodontitis promote the proliferation of anaerobic bacteria that produce unpleasant odors.
• Unsanitized dentures: Orthodontic devices and removable dentures, if not cleaned properly, can accumulate food debris and bacteria, contributing to bad breath.

When oral hygiene is not enough to solve the problem, other possible deeper causes need to be investigated.

Causes of halitosis: digestive disorders and health problems

In many cases, halitosis may be a symptom of an underlying medical condition. Digestive problems and systemic disorders can disrupt the body's balance and manifest as a bad breath.

Here are some of the most common disorders that can cause halitosis:

1. Gastroesophageal reflux disease (GERD).

Acid reflux can cause stomach contents to back up into the esophagus and into the mouth, bringing with it unpleasant odors. Those who suffer from GERD often experiences a bitter or sour taste in the mouth, accompanied by persistent halitosis.

2. Liver and kidney problems

Liver or kidney dysfunction can alter toxin metabolism, leading to persistent bad breath. Breath with a sweetish odor may be a sign of liver problems, while an ammonia-like odor may indicate kidney failure.

3. Respiratory tract infections.

Chronic sinusitis, bronchitis, and upper respiratory tract infections can cause mucus accumulation, which promotes bacterial growth and consequently bad breath.

4. Diabetes

In subjects with uncontrolled diabetes, the body uses fats as an energy source, producing ketone bodies that cause fruity smelling breath, typical of diabetic ketoacidosis.

If a medical cause of halitosis is suspected, it is important to see a physician for an accurate diagnosis.

Causes of halitosis: the importance of nutrition

Nutrition plays a crucial role in breath balance. (We discussed this in detail in the article devoted to the’nutrition and oral health ) Some foods can exacerbate the problem, while others can help counteract it.

Foods that worsen halitosis:

• Garlic and onion: contain sulfur compounds that, once absorbed into the bloodstream, are released through the breath.
• Dairy products: Milk and its derivatives promote bacterial fermentation in the mouth, increasing the risk of bad odor.
• Alcohol and coffee: they dehydrate the mouth and reduce saliva production, facilitating the proliferation of bacteria.
• Excess animal protein: Diets rich in red meat and fish can promote the accumulation of sulfur compounds responsible for halitosis.

Foods that help improve breath:

• Fruits and vegetables rich in water: Apples, celery and carrots stimulate saliva production and help eliminate food debris.
• Green tea and parsley: have antibacterial properties and neutralize volatile compounds responsible for halitosis.
• Yogurt and probiotics: they improve intestinal flora and reduce the proliferation of harmful bacteria.

A balanced diet, rich in fiber and low in refined sugars, helps maintain a fresh breath in a natural way.

Effective solutions to combat halitosis

Countering halitosis requires a targeted approach that includes oral hygiene, balanced diet, and, if necessary, specific treatments.

1. Improving oral hygiene

• Brushing teeth at least twice a day and floss to remove food debris between the teeth.
• Use one tongue brush or a tongue cleaner to eliminate the bacteria responsible for bad breath.
• Choose an antibacterial mouthwash based on. chlorhexidine or zinc, which helps neutralize odors.

2. Keeping the mouth hydrated

• Drink at least 2 liters of water per day To promote saliva production.
• Chew sugar-free chewing gum to stimulate salivary glands.
• Avoid excessive alcoholic beverages and coffee, which contribute to oral dryness.

3. Consult a specialist

If halitosis persists despite proper oral hygiene, it is advisable to consult a dentist or a physician To identify any hidden causes.

Some useful tests for diagnosis include:

• Dental examination to rule out caries or gum disease.
• Breath test to detect the presence of sulfur compounds.
• Blood tests to check for systemic diseases.

4. Natural remedies for fresh breath

• Chew fennel seeds or cloves For their antibacterial properties.
• Drink herbal tea made from mint or sage, which naturally freshen the breath.
• Prepare a do-it-yourself mouthwash with water and baking soda, useful for neutralizing acids in the mouth.
