Parents often observe their babies coughing during the teething phase. While teething itself does not directly cause a cough, associated factors frequently coincide with this developmental milestone. Understanding this helps parents identify if the cough is a typical reaction to teething or a sign of something more significant. This article explores common reasons for coughing during teething and offers guidance on when professional medical advice may be necessary.
Understanding the Drool-Cough Connection
Excessive saliva production is a primary reason babies cough while teething. As new teeth erupt, babies produce increased drool. This heightened saliva accumulates in the throat, triggering a gag reflex or clearing cough as the baby manages the excess liquid. This cough is typically mild, wet, and does not affect the baby’s well-being or breathing.
The body’s gag reflex acts as a protective mechanism, preventing foreign objects and fluids from entering the airway. When a baby’s throat receives a large amount of saliva, this reflex may activate, resulting in a cough or gagging. This response is normal and not a symptom of illness. Parents might notice these coughing fits more frequently when the baby is lying down, as gravity can cause saliva to pool in the throat.
Other Common Reasons for Coughing During Teething
Beyond excessive drooling, other factors can lead to coughing during teething. Babies explore their environment more with their mouths, putting objects and hands into their mouths to soothe sore gums. This increased oral exploration can expose them to more germs, potentially leading to mild infections like colds or congestion, causing a cough.
Congestion from a mild cold can result in postnasal drip, where mucus trickles down the back of the throat. This irritation can trigger a cough as the baby tries to clear their throat. While teething itself does not directly cause a runny nose or congestion, the stress of teething might make infants more susceptible to common childhood illnesses, which can include these symptoms.
Some babies may also experience an increase in reflux symptoms during teething. Although teething does not directly cause reflux, the discomfort and changes in feeding patterns associated with teething can exacerbate existing reflux. When stomach contents or excess swallowed saliva come back up, it can irritate the esophagus and throat, leading to a cough.
When to Consult a Doctor
While some coughing during teething is normal, certain signs indicate a baby’s cough warrants medical attention. Parents should consult a doctor if the cough is accompanied by a high or prolonged fever, especially in infants under three months of age. A fever of 100.4°F (38°C) or higher, particularly if it lasts longer than three days, requires medical attention.
Difficulty breathing, rapid breathing, or visible effort when breathing are serious indicators requiring immediate medical evaluation. Wheezing, a high-pitched whistling sound during breathing, or rattling sounds in the chest also warrant concern. Other red flags include blue lips or fingernails, excessive sleepiness or lethargy, significant loss of appetite, or signs of dehydration. If the cough is persistent, severe, worsening, or accompanied by vomiting, seek professional medical advice.
