In 30% of the adult population, bad breath can be a constant concern, affecting not only oral health but also personal confidence.

At Clínica Curull, we understand the importance of a healthy and fresh smile. Our halitosis treatment focuses on restoring your security with excellent oral health.


Halitosis, one of the oldest social problems, popularly called “bad breath”, is defined as an unpleasant odor that comes from the oral cavity.

It is a concern that is demoralizing and negatively impacts the lives of millions of people. For a long time, bad breath was related to diseases of the stomach, maxillary sinuses, or lungs.


Today it has been medically proven that, in 90% of cases, bad breath comes from the mouth and is produced by the bacterial decomposition of food remains between the teeth, saliva, cells of the oral mucosa, or blood between teeth.

Currently, despite popular beliefs, there are effective treatments that not only change bad breath, but also help improve self-esteem and emotional problems derived from patients with halitosis.


There are different causes for the appearance of this condition, the most common are the following:

  • Reduced salivation during the night can cause bad breath when you wake up.
  • Follow an unstable diet with a low calorie intake or fast.
  • Long-term alcohol and tobacco use can trigger an unpleasant odor in exhaled breath.
  • The decrease in salivary flow, since the glands responsible for producing saliva weaken with age. This deterioration makes it difficult to eradicate bacteria.
  • Poor oral hygiene and careless oral hygiene habits. This can cause bacterial plaque on the surface of the tongue, as well as the presence of cavities or periodontal diseases such as gingivitis or periodontitis.
  • Having gastrointestinal diseases can cause an odor in the mouth that, along with oral health problems, contributes to halitosis.

Do you want to know if you suffer from halitosis? Answer the following questions, and you will easily know whether or not you suffer from bad breath:

  1. Do you have a white or yellowish coating on your tongue?
  2. Do you experience dry mouth, thick saliva, or a burning tongue sensation very often?
  3. Have you experienced the sensation of a bad taste in your mouth (bitter, sour…)?
  4. Have you been using mints, mouthwashes, or gum to mask your feeling of bad breath?

Frequent Questions

If I have bad breath, does that mean I have stomach problems?

The most frequent origin of bad breath lies in the oral cavity, exactly in the gums and tongue, and it is the dentist who can help you solve it. Most patients who have bad breath usually have periodontal infections, that is, gingivitis and periodontitis, diseases that, if not treated in time, lead to the loss of all teeth and molars. A minimal percentage of halitosis has its origin in respiratory and stomach problems.

Can bad breath be “measured or quantified” in an objective way?

At Clínica Curull we have a device called “Halimeter” that allows us to measure the volatile sulfurs responsible for bad breath in order to have an objective view of the problem and be able to treat the pathology that produces it.

Are the use of specific pharmaceutical products for bad breath indicated for the treatment of halitosis?

The products that are marketed for the treatment of halitosis only temporarily mask bad breath, but do not treat it. To do this, we must know the exact origin of halitosis (oral or extraoral), and thus be able to treat it correctly.

Are there foods that cause halitosis?

Foods with strong odors such as onions, garlic, certain cheeses, strong spices, and foods high in fermentable sugars can temporarily cause bad breath. Additionally, high protein diets can lead to increased production of sulfur compounds, which can also cause bad breath. However, this set of unpleasant odors is usually temporary and can be eliminated as long as proper oral hygiene is performed.

What is the difference between intraoral halitosis and extraoral halitosis?

The difference is based on its origin and cause. On the one hand, intraoral halitosis originates within the oral cavity. It is mainly caused by bacteria that accumulate in the mouth, on the tongue, gums, or teeth. Which can cause periodontal diseases, bacterial plaque, and cavities that can contribute to halitosis. On the other hand, extraoral halitosis has its origin outside the oral cavity. Rather, it is related to health problems that do not originate directly in the mouth, such as gastrointestinal problems, and respiratory diseases, among other factors.
