No, teething does not cause a runny nose. Many parents notice nasal discharge around the age their babies start teething, but this is purely coincidental. A runny nose is usually caused by infections, allergies, or environmental factors, not tooth eruption.
It can be worrying when your baby seems uncomfortable and you’re unsure what’s happening. Knowing which symptoms are truly related to teething, and when to seek help for pediatric emergencies, helps you provide the right care without unnecessary stress.
When Does Teething Start
Teething generally begins between 4 and 7 months of age, although some babies start earlier or later. While parents may notice symptoms like runny nose during this period, research shows these symptoms are not caused by teething itself. In a prospective study of 125 healthy infants, no symptom, including nasal congestion or runny nose, occurred more than 20% more often during teething than non-teething periods, demonstrating that runny nose is likely coincidental rather than a direct result of tooth eruption
How To Tell If Baby Is Teething
- Increased Drooling: Extra saliva is common when gums are irritated.
- Chewing On Objects: Babies often gnaw on toys or fingers to relieve gum pressure.
- Irritability/Fussiness: Mild mood changes occur during teething discomfort.
- Sensitive Or Swollen Gums: Inflamed gums may appear where teeth are about to erupt.
Does Teething Cause Runny Nose
No, teething does not cause a runny nose. While it’s common for babies to develop nasal discharge around the same age they start teething, medical evidence confirms there’s no direct link between tooth eruption and a runny nose. Runny nose in infants is almost always due to viral infections, colds, allergies, or environmental irritants.
Other Causes Of Runny Nose
A runny nose in babies is typically a symptom of something other than teething. Nasal discharge often signals an immune response to infections or exposure to allergens, irritants, or environmental triggers. Understanding the real causes helps ensure babies get proper care when needed.
- Viral Infections: The most common cause, including colds and mild respiratory viruses.
- Allergies: Environmental allergens can trigger sneezing and runny nose.
- Environmental Irritants: Smoke, dust, or strong odors stimulate mucus production.
- Sinus or Ear Infections: Can cause nasal discharge alongside fever or irritability.
Other Causes Of Teething Misattributed Symptoms
Many symptoms often blamed on teething are actually unrelated. Babies at teething age are exposed to more germs and may show coincidental signs of illness.
- Fever: Typically caused by infections, not teething.
- Diarrhea: Usually due to viral infections or dietary changes.
- Rash on Face: Drool rash is common, but other rashes are often unrelated.
- Prolonged Crying: May indicate illness rather than gum discomfort.
How Long Does Teething Last
Teething is a process from about 4–7 months to 2–3 years, as all 20 primary teeth emerge. Each tooth usually causes mild gum discomfort a few days before and after breaking through.
When to See a Doctor
Most runny noses during the teething period are mild and harmless, but there are times when professional evaluation is necessary. Persistent, severe, or unusual symptoms may indicate an infection, allergy, or other underlying medical issue that needs prompt attention. Signs you should contact a doctor:
- High Fever: Temperature above 100.4°F (38°C) that doesn’t improve with home care.
- Persistent Runny Nose: Nasal discharge that lasts more than 10–14 days or changes color.
- Breathing Difficulty: Wheezing, rapid breathing, or noticeable effort to breathe.
- Severe Irritability or Poor Feeding: When fussiness or feeding issues last longer than expected.
- Dehydration Signs: Reduced wet diapers, dry lips, or lethargy.
If your baby shows any of these symptoms, contact the Texas Emergency Care Center for immediate evaluation and care.
Treatment For Runny Nose And Teething
Proper care involves addressing your baby’s teething discomfort while also managing the real cause of a runny nose. Supportive care, home remedies, and pediatric guidance ensure your baby stays comfortable and healthy.
Treatment For Teething
- Cool Teething Rings: Chilled (not frozen) teething toys help soothe sore gums.
- Gum Massage: A clean finger or cool cloth gently pressed on gums can relieve discomfort.
- Pain Relief Medicine: Under pediatric guidance, infant acetaminophen or ibuprofen may ease teething pain.
- Comfort Measures: Extra cuddles, rocking, or breastfeeding can reduce fussiness linked to gum discomfort.
- Teething Wipes or Gels: Only use pediatric-recommended products; some gels can numb gums temporarily.
Treatment For Runny Nose
- Saline Nasal Drops: Helps loosen mucus and clear nasal passages safely.
- Humidifier: Using a cool-mist humidifier adds moisture to the air, easing congestion.
- Gentle Suction: A bulb syringe or nasal aspirator can remove excess mucus.
- Hydration: Frequent feeds or fluids keep your baby hydrated and help thin mucus.
- Monitor & Seek Care: If the runny nose is accompanied by fever, colored discharge, or irritability, contact your pediatrician.
