小孩子有口臭What to do
Generally, bad breath in children may be caused by incomplete oral cleaning, improper diet, dental caries, gingivitis, indigestion accompanied by gastroesophageal reflux, and other factors. Depending on the specific situation, improvements can be achieved through general management, medication, or surgical treatment. Detailed analysis is as follows:
1. Incomplete Oral Cleaning
Food residues remaining in the mouth are broken down by bacteria, producing unpleasant odors. Parents should help children brush their teeth twice daily using a child-specific toothbrush, rinse with warm water after meals, and regularly use dental floss to clean between teeth to prevent accumulation of food debris.

2. Improper Diet
Excessive consumption of sweets and fried foods, or eating before bedtime without subsequent oral cleaning, easily promotes bacterial growth and leads to bad breath. Adjust the child's diet by reducing intake of sweets and fried foods, avoiding eating before sleep, and promptly cleaning the mouth after meals.
3. Dental Caries
Bacteria erode the tooth structure, forming cavities where trapped food ferments and produces odor. Under medical guidance, sodium fluoride glycerin paste, silver nitrate solution, or ammoniated silver nitrate solution may be used to inhibit decay progression. For deeper cavities, dental fillings (restorations) should be performed to repair the affected tooth.
4. Gingivitis
Poor oral hygiene leads to plaque buildup, which irritates the gums and causes inflammation, often accompanied by gum bleeding and bad breath. Under medical supervision, use of compound chlorhexidine mouthwash or hydrogen peroxide solution may help. In cases of severe inflammation, oral amoxicillin granules may be prescribed, along with supragingival scaling to remove dental plaque.
5. Indigestion with Gastroesophageal Reflux
Gastrointestinal dysfunction leads to indigestion, and stomach contents may reflux into the mouth, causing bad breath. Under medical guidance, medications such as pediatric spleen-strengthening and stagnation-dissolving oral liquid, xingpi yang'er granules, or domperidone suspension may be administered. Maintain regular eating habits, avoid overeating, and do not let the child lie flat immediately after meals.
In daily life, cultivate good oral hygiene habits in children; maintain a regular diet rich in vegetables and fruits; schedule routine dental checkups to detect oral problems early; encourage light physical activity after meals to promote gastrointestinal digestion and reduce reflux episodes.
