Causes and Improvement Methods of Children’s Bad Breath

Question

My child is three years old, and there is often an unpleasant smell in his mouth.

Answer

1. Oral lesions.
2. Nasal diseases, such as rhinitis, sinusitis, etc.
3. Throat diseases, such as tonsillitis, pharyngitis, laryngitis, etc.
4. Gastrointestinal diseases, such as reflux gastritis, esophageal relaxation, etc. Although there are many possible causes, most are related to oral issues. Therefore, it’s important to first consult a dentist to actively treat any oral disorders and ensure proper and effective brushing, including the tongue. If the condition does not improve, it may be necessary to consult an otolaryngologist and a gastroenterologist.
