Dr. Zhou Xiaofeng
The main causes of bad breath in infants include the following:
1. **Oral hygiene issues**: Poor oral cleanliness can lead to food residues fermenting in the mouth and producing an odor.
2. **Oral diseases**: Conditions such as dental caries, gingivitis, and periodontitis allow oral bacteria to break down food residues, causing bad breath.
3. **Gastrointestinal problems**: Infants have weaker digestive function; conditions such as indigestion and gastroesophageal reflux may also lead to bad breath.
4. **Dietary habits**: Consuming excessive amounts of spicy or hard-to-digest foods may also trigger bad breath.
In addition, nasal cavity diseases and respiratory tract infections can also cause bad breath in infants. Parents should carefully monitor their baby's condition. If the bad breath persists or worsens, timely medical examination and treatment are necessary.
