What should I do if my 3-year-old child drools?

Babies often drool, and many parents don’t know why. Often when people talk to their babies, their faces will be covered with drool. Because we think drooling is normal, many parents do not take their babies to see a doctor, and naturally they do not think about the cause of drooling. So why do 3-year-old babies often drool? What is the reason?

The baby is in the period when the deciduous teeth are gradually erupting. There are many tooth germs buried in the gums. These tooth germs must break through the obstruction of the gums to grow out, which will inevitably stimulate the gums and make them itchy. Under the stimulation of nerve reflex, the salivary gland secretion will increase. The baby's mouth is shallow and the oral capacity is small. The baby cannot use swallowing to regulate the saliva in the mouth. When there is a little more saliva in the mouth, it will flow out naturally. The baby's ability to inhibit saliva secretion and swallowing function are slightly poor. Often drooling.

The main reasons are as follows:

1. When you first wear dentures, you will feel uncomfortable and have a noticeable foreign body sensation, which will stimulate increased saliva secretion. The retention of saliva will stimulate the mucous membrane and cause nausea. Mucosal pain, redness, swelling and ulcers can all cause increased saliva secretion.

2. Oral diseases such as caries, acute and chronic inflammation, and periodontal disease.

3. Oral mucosal diseases, such as patients with recurrent aphthous stomatitis, herpetic stomatitis, and chronic recurrent aphthous stomatitis. There are too many missing teeth in the mouth, which causes more saliva to flow when speaking and the lips cannot hold it.

4. Alzheimer's disease, cerebral atrophy, and other brain diseases.

5. Any stimulation to the mucous membranes of the digestive tract, such as the esophagus and stomach, can reflexively lead to saliva secretion.

6. The sense of smell, vision and hearing can perceive the color, aroma and taste of food. Eating sour, sweet, bitter and spicy food forms conditioned stimulation, which induces excitement of the saliva secretion center through the corresponding centers and cerebral cortex, causing large amounts of saliva to be secreted.

It is normal for babies to drool when they are young. Because their chewing ability and facial muscle contraction ability are relatively weak, it is easy for them to not be able to close their mouths. Drooling will often occur, so there is no need to worry too much.
