Children’s drooling is medically known as salivation, which can be divided into physiological salivation, such as stimulation of milk teeth eruption, salivary gland function is not yet perfect, and pathological salivation, which is often caused by oropharyngeal inflammation, respiratory tract infection, neurological diseases, etc. Parents need to take their children to the doctor in time to analyze the specific symptoms and relevant examination results of their children, and then treat them after a clear diagnosis. Common causes and treatment a. Physiological salivation is common in infants and toddlers, generally from 4 months to 3 years old, salivation is common because the function of salivary glands has not yet been perfected or stimulated by the eruption of milk teeth, resulting in increased saliva secretion, at this time the child’s ability to regulate the muscles is poor, chewing ability is weak, swallowing function is poor, so the phenomenon of drooling will occur. Generally, no special treatment is needed. When the teeth erupt and the depth of the mouth increases, infants and children gradually learn to swallow, and the drooling will gradually disappear. Pathological salivation 1, oropharyngeal inflammation: such as tongue inflammation, gingivitis, hand, foot and mouth disease, chicken pox, mouth ulcers, etc., due to inflammatory stimulation led to increased saliva secretion, and due to oral pain, resulting in children swallowing difficulties, causing drooling situation. Can follow the doctor’s instructions to use acyclovir, amoxicillin capsules, metronidazole and other drugs to treat; 2, respiratory tract infections: such as colds, tonsillitis, pharyngitis, etc., due to nasal obstruction, poor breathing, the child will breathe through the mouth, which leads to poor swallowing, the performance of drooling. At this time, under the guidance of the doctor, the use of blue scutellaria oral solution, ibuprofen suspension mixture and other symptomatic treatment; 3, neurological diseases: such as encephalitis, medullary paralysis, carbon monoxide poisoning, meningitis sequelae, facial nerve palsy, mental retardation, cerebral palsy, etc., due to damage to the nerves governing the salivary glands, resulting in salivary secretion dysfunction, and cause drooling. In this case, we should actively search for the cause and give anti-infection, cranial pressure lowering, nerve nutrition and other treatments. If the child is physiologically drooling at a young age, parents are advised to replace the bib or saliva bib in a timely manner to prevent discomfort from saliva soaked skin.
