Many parents observe their babies experiencing nasal congestion during teething. While tooth emergence is a natural developmental stage, some symptoms, like a runny nose, are often misunderstood. This article explores the scientific understanding behind these observations, clarifying the causes of a snotty nose in teething babies.
Understanding Teething Symptoms
Teething involves the eruption of a baby’s first teeth through the gums. Common signs include swollen, tender, or red gums where a tooth is emerging. Babies may also exhibit increased drooling, fussiness, irritability, and changes in eating or sleeping patterns. A mild elevation in temperature, below 100.4°F (38°C), can also occur. These symptoms arise a few days before a tooth cuts through and can persist for a short period afterward.
The Indirect Link: Teething and Nasal Congestion
A runny nose is not a direct symptom of teething, but several indirect factors can lead to nasal congestion during this stage. Teething can stimulate inflammatory substances in the body, leading to increased mucus production and nasal congestion.
Babies put more objects into their mouths to relieve gum discomfort. This increased mouthing exposes them to more germs and allergens, increasing the risk of minor infections that cause nasal discharge. The stress or inflammation associated with teething can also temporarily affect the baby’s immune system, increasing susceptibility to common colds and other viral infections.
Excessive drooling also contributes to nasal issues. Constant saliva flow can irritate the skin around the nose and mouth, and increased moisture can indirectly affect nasal passages. While a clear runny nose can be related to this inflammatory response, green or yellow snot indicates a viral infection, not directly caused by teething.
When to Seek Medical Advice
Differentiate between typical teething discomfort and signs of illness. If a baby develops a high fever, above 100.4°F (38°C), it is likely due to a virus or bacterial infection, not teething. For infants younger than three months, any fever warrants a doctor’s visit.
Seek medical advice if the baby experiences a severe cough, difficulty breathing, or persistent symptoms. Other indicators include a rash, diarrhea, vomiting, ear pulling, or severe pain. A runny nose that does not improve after 10 days, or one accompanied by increasing fussiness or worsened symptoms, also warrants professional evaluation.
Caring for Your Teething Baby
Providing comfort can alleviate a teething baby’s discomfort, including any associated nasal congestion. Gently wipe the nose to remove excess mucus and prevent skin irritation. For congestion, use a bulb syringe or nasal aspirator to clear nasal passages.
Before using an aspirator, administer saline drops to moisten and thin mucus, making it easier to remove. Use these devices gently and not more than four times daily to avoid irritating the nasal lining. Offering safe teething toys, a cool washcloth, or gently massaging the gums with a clean finger can also provide relief. Ensuring the baby stays well-hydrated also helps during this period.
