Why is my baby drooling so much?

It is a common physiological phenomenon for babies to drool, which is related to the incomplete development of the child's oral cavity and teething. In addition, food residues and bacterial growth can easily cause children to drool. As a parent, you should wipe the child's saliva in time to avoid eczema or allergies in the child, and keep the child's mouth clean.

1. Oral problems

(1) Imperfect oral function. Imperfect body functions are the prominent feature of babies, and the leakage of saliva in children is attributed to imperfect oral functions. At this time, the child's mouth is small and shallow, causing saliva to flow out easily. The nervous system that regulates swallowing is not perfect, and it is difficult for children to reduce the amount of saliva by swallowing.

(2) Food residues. Some children wake up with a wet, yellowish area on their pillow that tastes salty. This is most likely caused by oral problems. Most babies do not have the habit of brushing their teeth, so there is a lot of food residue in their mouths. Many children will suffer from tooth decay, gingivitis, etc., and the amount of saliva in their mouths will also increase.

(3) Bacterial growth. The temperature of the mouth can provide a breeding ground for bacteria. Once the mouth is invaded by bacteria, it will cause pain, which will stimulate the salivary glands.

2. External stimulation

(1) Solid food. When your child starts eating solid food, your baby's mouth is no longer as dry as before, and the amount of saliva will increase. The salivary glands will secrete a large amount of saliva under the stimulation of complementary food.

(2) Bad habits. If babies often put their fingers or small objects in their mouths, it will also stimulate the salivary glands.

drug. Medications are also a major cause of increased drooling. For example, some babies will drool unconsciously when taking epilepsy medications.

3. Dental problems

(1) Long teeth. When a child starts teething, their mouth becomes flooded with saliva. At this time, the deciduous teeth break through the restrictions of the gums and grow outward, and the gums will feel painful. Since the nerves in the oral cavity are a whole, the nerves in the salivary glands will also react, causing their secretion.

(2) Buck teeth. Some babies have difficulty closing their lips when sleeping, and drool often flows out. Often these children have front teeth that protrude so far forward that they are difficult to be covered by the lips.

4. Neuroregulation disorders

(1) Being too excited during the day. A small number of babies drool in their sleep due to neurological disorders. This is because some children are abnormally excited during the day, and their nervous system remains in this state at night, which affects the function of the salivary glands.

(2) Systemic diseases. Some children suffer from diseases, especially systemic diseases, whose entire nervous system may be in a state of disorder and their saliva secretion may be abnormal.
