1, the baby's oral hygiene is not good. After the baby eats sweets or drinks milk, the mother fails to clean the baby's mouth in time, or the baby overflows milk at night, leaving the milk in the mouth, which leads to the growth of oral bacteria and odor. Some babies have teeth, and food residues remain in the gaps of the teeth, rotting and fermenting, giving off an unpleasant smell.
2. Oral diseases. A, oral bacterial infection, such as mold infection (mold from the mother's birth canal or contaminated milk utensils, or caused by taking antibiotics for a long time due to a certain disease) can lead to thrush, and then oral odor. If the mold is brought by the mother, that is, the mother suffers from fungal vaginitis when she is pregnant, in this case, the baby's bad breath will be more stubborn, and targeted treatment can be taken. B, oral mucosal inflammation, gingivitis, periodontitis, oral ulcer with suppuration, bad breath will also occur. C, indigestion or intake of food containing too much soap protein or greasy, constipation, small mouth will stink.
3. Systemic diseases. When the baby suffers from systemic diseases such as hepatitis and lung abscess, the body's immunity is poor, and some punctate or miliary ulcers will appear in the mouth, leading to bad breath and loss of appetite.
4, oral bacterial imbalance can cause bad breath. Everyone has a certain proportion of bacteria in his mouth. When the proportion is out of balance, it will cause oral diseases. The most direct symptom is bad breath, and the baby will lose appetite and cry.
Therefore, it is very important to do a good job in baby's oral care:
Although the baby is small, it should be treated with oral care 2~3 times a day like an adult. Babies will inevitably have some minor illnesses, and they should pay more attention to oral care during illness. Don't let your baby sleep with a pacifier at night, which is prone to tooth decay or lower teeth covering upper teeth. Cleaning your baby's mouth in time every day will make your baby form a habit, that is, you will have the consciousness of cleaning your mouth. Clean gauze can be wrapped around adults' fingers (or dipped in boiling water or light salt water with a cotton swab). After the baby drinks milk, scrub the baby's gums and tongue, the bottom of the jaw and the upper jaw. On the one hand, it cleans teeth, on the other hand, it can promote the eruption of deciduous teeth. When scrubbing, the action must be gentle to prevent excessive force or rough gauze from hurting the baby's oral mucosa. After the baby drinks milk, give the baby some water and rinse his mouth with clear water.
Because the baby's immunity and disease resistance are low, when kissing the baby, adults are likely to pass the germs and viruses in their mouths, especially those transmitted through the respiratory tract, to the baby. So refuse adults to kiss babies.
