During teething, a child may experience a decrease in immunity, which sometimes leads to a runny nose, cough, fever, or digestive upset. It is important to closely monitor the child's health. Symptoms when a runny nose is considered normal: * Increased nasal discharge. * Absence of nasal congestion. * Mild runny nose that lasts for three days. * Clear and watery mucus. These symptoms arise due to increased blood circulation in the gums, which are connected to the nasal mucosa, leading to mucus secretion. However, a runny nose is not always associated with teething. Normally, a child should not have other symptoms besides gum tenderness. If the runny nose becomes severe, nasal congestion appears, and the mucus changes color to green or white, it is necessary to consult a doctor. This may indicate an acute respiratory viral infection (ARVI) rather than teething. What to Do If a Runny Nose Appears? Often, no action is needed, as the runny nose resolves within 3-4 days. However, if the discharge interferes with the child's breathing, the following can be done: * Rinse the nose and moisturize the mucosa. This can be done using saline solution, seawater or regular water, saline solution, or nasal drops. * Remove mucus using a pipette or aspirator. If the runny nose does not go away after 6 days, it is advisable to consult a pediatrician. Decongestant drops are not recommended for use beyond this period. A runny nose in children under one year is often associated with teething, but this is not always the case. If there is also a fever and cough, this may be a sign of ARVI, as a decrease in immunity can make the child susceptible to infection.
