Children spitting, may be caused by physiological reasons, may also be gingivitis, herpes pharyngitis and other diseases. 1. Physiological reasons: when the child is in the teething period, the teeth will produce stimulation of the nervous system, resulting in the oral secretion of a large amount of saliva, and the child’s swallowing system is not well developed, resulting in the performance of unconscious spitting. Some children will also spit like a joke due to mischief, which is a bad habit. 2. Gingivitis: If children do not pay attention to oral hygiene or often open-mouth breathing, it is easy to gingivitis, which in turn leads to a bad taste in the mouth, abnormal gum color, spitting and other symptoms. 3. Herpes pharyngitis: due to the child’s weak resistance, it is easy to cause viral infections, resulting in herpes pharyngitis, which in turn leads to fever, vomiting, mouth ulcers, spitting and other phenomena. In conclusion, spitting in children can be caused by different reasons. If your child frequently spits with other symptoms, it is recommended to consult a doctor in time.
