TL;DR
- Teething usually starts around 6 months and can cause fussiness, drooling, and tender gums; a runny nose around this time is often coincidental.
- Increased saliva and gum changes during teething may slightly irritate nasal passages, but teething does not directly cause a true runny nose.
- Common causes of a runny nose in children include cold weather, crying, irritants, colds or flu, nasal obstruction, sinus or adenoid infections.
- Less common causes include choanal atresia, pyriform aperture stenosis, deviated nasal septum, nasal polyps, and rare nasal cysts or tumours.
- Seek medical attention if mucus persists, is colored, if there’s a high fever, additional symptoms, facial swelling, or signs of dehydration.
- Comfort a teething baby by keeping them hydrated, easing nasal congestion, soothing gums, maintaining hygiene, giving gentle massages, and dressing them in soft, breathable clothing.
- Pediatric dentists can guide safe teething practices, recommend teething toys or gels, and check for early dental issues to support your baby’s oral health.
Does Teething Really Lead to a Runny Nose in Babies?
Teething is a natural part of a baby’s growth when their first teeth begin to push through the gums. It usually starts around 6 months of age, though the timing can differ for every child. During this stage, babies may become fussy, drool more than usual, and have swollen or tender gums. Along with these common signs, many parents also notice that their baby develops a runny nose and wonder if the two are connected.
So, can teething cause a runny nose, or is it just a coincidence? Let’s take a closer look.
Teething and Runny Nose: Is There a Connection?
Many parents notice that their baby gets a runny nose around the same time new teeth start to come in. It is easy to think the two are connected because teething does cause changes in the mouth and gums. When babies are teething, their gums can become slightly swollen and tender, and they produce more saliva than usual. This extra drooling may sometimes irritate the throat or nasal passages, making the nose seem a little runny.
However, doctors explain that teething itself does not directly cause a true runny nose. In most cases, the nasal discharge or congestion happens because babies are more likely to catch mild viral infections at this stage. Their immune systems are still developing, and they tend to put objects in their mouths, which increases their chances of picking up germs. So, while teething and a runny nose often occur together, it is usually just a coincidence rather than a direct connection.
Now that you have the answer to “Can teething cause a runny nose?” let’s take a look at the common causes of a runny nose.
What are the Causes of a Runny Nose in Children?
The nose makes mucus, which keeps it wet inside and catches germs before they go in deeper. Usually, the body pushes mucus back into the throat, and we swallow it. When too much mucus runs through the nose instead of going down the throat, it’s called a runny nose or rhinorrhea.
Mucus can be thick or thin and can be see-through or not. Usually, a runny nose goes away by itself.
In children, some common causes of a runny nose are
- Cold Weather: Sometimes, the body makes more mucus when exposed to cold temperatures.
- Crying: When a baby cries, tears can drain through the nose, causing it to run.
- Irritation: Being around irritants such as smoke, strong smells, or pollution can trigger nasal discharge.
- Colds and Flu: Viral infections like the common cold or influenza can cause the nose to fill with mucus and run.
- Obstruction: Something foreign, like a small object, can get stuck in the nose and cause a runny nose.
- Sinus Infection: In adults, the spaces in the face (sinuses) can get filled with infected mucus during sickness, making the nose run. This is rare in babies because their sinuses are not fully grown.
- Adenoid Infection: The adenoids are tissues at the back of the nose, and if they get infected, it can make the nose run.
Less common causes of a runny nose include:
- Choanal Atresia: This is when something closes off the back of the nose. Doctors usually find it soon after birth, but it might not be noticed for a while if it’s only on one side.
- Pyriform Aperture Stenosis: This is when the bony opening of the nose is too narrow, blocking it.
- Deviated Nasal Septum: The wall inside the nose can lean to one side, blocking it. This can happen from birth or after a nose injury.
- Nasal Polyps: These are growths in the nose lining that can make the nose run. They look like grapes.
- Nasal Cysts or Tumors: These are rare but can block the nose. Sometimes, they can be cancerous and usually grow on one side of the nose.
When to Worry About a Runny Nose in a Teething Baby?
While a runny nose can be common, certain signs may indicate something more serious:
- Persistent or Colored Mucus: A runny nose that lasts several days or produces yellow or green mucus may signal an infection.
- High Fever: A temperature above 100.4°F (38°C) should be monitored closely and may require medical attention.
- Facial Pain or Swelling: Swelling around the eyes or face could indicate a sinus or other infection.
- Signs of Dehydration: Fewer wet diapers, dry lips, or crying without producing tears can show your baby is not getting enough fluids.
- Additional Symptoms: Coughing, unusual sleepiness, or difficulty breathing are some more warning signs.
If any of these symptoms appear, it is important to consult a pediatrician promptly.
How to Comfort a Teething Baby with a Runny Nose
Teething can be uncomfortable for babies, and sometimes they may also have a runny nose. Here’s how you can help your little one feel better:
- Keep Baby Hydrated: Offer frequent breastfeeds, formula, or water (if age-appropriate) to prevent dehydration.
- Ease Nasal Congestion: Use gentle nasal suction or saline drops to clear the nose and help your baby breathe more easily.
- Soothe Sore Gums: Teething toys or a gentle gum massage can relieve discomfort.
- Maintain Hygiene: Clean hands, wipe the nose, and keep toys sanitized to prevent secondary infections.
- Gentle Chest or Back Rubs: Light massages can help your baby feel calm and aid in easier breathing.
- Soft, Comfortable Clothing: Dress your baby in breathable layers to avoid overheating, which can worsen discomfort.
How Dentists Can Help
Pediatric dentists can provide guidance on safe teething practices, recommend teething toys or gels if needed, and check for early signs of dental issues. Consulting a dentist can reassure parents and ensure your baby’s oral health is on track while managing teething discomfort.
