Teething is a normal developmental stage when an infant’s first teeth emerge through the gums. This process starts around six months of age, though it can vary from three months to after their first birthday. Parents frequently observe changes in their babies during this period and may wonder which symptoms relate to teething.
Common Signs of Teething
When a baby is teething, several localized symptoms appear. Increased drooling is a widespread sign, often leading to a facial rash around the mouth and chin due to constant moisture and irritation. Babies also chew on objects, seeking to relieve pressure or discomfort in their gums. Gum pain is mild, and the gums may appear swollen or red where a tooth is about to emerge.
Behavioral changes also occur. Infants may become more fretful or irritable than usual, and their sleeping patterns might be disrupted. There can also be slight changes in appetite, particularly a decreased interest in solid foods. Some babies may experience a mild temperature elevation, less than 101 degrees Fahrenheit (38.3 degrees Celsius).
Are Runny Nose and Cough Teething Symptoms?
A common misconception among parents is that teething directly causes symptoms such as a runny nose and cough. However, scientific consensus indicates that these respiratory symptoms are not direct results of the teething process. Teething is a localized phenomenon affecting the gums and does not cause systemic symptoms like fever, diarrhea, or respiratory issues.
The appearance of a runny nose or cough during the teething period is more often coincidental, as infants between 6 and 30 months are frequently exposed to common colds, viruses, or allergies. During this age range, a baby’s immune system is still developing, and the protective antibodies transferred from the mother at birth begin to decrease, making them more susceptible to infections. While increased drooling can sometimes lead to a “teething cough” if saliva goes down the throat, and inflammation around erupting teeth might indirectly contribute to a clear, short-lived runny nose, these are considered secondary or coincidental. If a runny nose involves colored mucus (green or yellow) or lasts longer than two to three days, it is more likely indicative of a viral infection.
When to Consult a Doctor
Parents should seek medical attention for their infant if symptoms are concerning, regardless of whether teething is occurring. A persistent or worsening runny nose, especially if accompanied by thick or colored mucus, warrants a doctor’s visit. A persistent cough, particularly if it is severe, causes difficulty breathing, or lasts longer than a few weeks, also requires medical evaluation.
Immediate medical attention is advised for a high fever, specifically if a baby under 12 weeks old has a temperature of 100.4°F (38.0°C) or higher, or if a baby over 12 weeks has a persistent temperature above 104°F (40°C). Other indicators for consulting a healthcare provider include poor feeding, unusual drowsiness or lethargy, signs of dehydration (such as decreased urination or no tears when crying), or any other signs of significant illness. If there is any doubt about an infant’s symptoms, contacting a pediatrician is recommended.
