Patient's question:
Does the child often drool, is it a cold?Doctor's answer:
Children drooling is generally caused by the following factors:1. Poor oral hygiene: The temperature and humidity in the mouth are most suitable for bacterial growth. The accumulation of food residue or sugary substances in the gaps between teeth and on tooth surfaces can easily lead to tooth decay and periodontal disease. These adverse factors can stimulate the mouth, causing drooling during sleep.
2. Malocclusion of front teeth: This may be caused by genetic factors or acquired bad habits such as biting nails, sticking out the tongue, or chewing pencil tips, resulting in malocclusion of the front teeth and drooling during sleep.
3. Neurological regulation disorders: Saliva secretion is entirely regulated by neural reflexes. The phrase "yearning for plums" is an example of conditioned reflexive saliva secretion in daily life. If a child still drools after the age of 2–3, it is recommended to visit a pediatrician for a professional examination, including tests and evaluations of neurological, brain, swallowing, and muscle function, to ensure timely treatment.
