Can Teething Cause Runny Nose

Key Takeaways

• Teething may coincide with mild symptoms, but a persistent runny nose is usually caused by something else.
  
• Increased drooling during teething can irritate the skin and contribute to a teething rash or a rash on the face when teething.
  
• Research shows that teething does not directly cause infections, fever, or significant nasal symptoms.
  
• Symptoms like teething fever or teething and diarrhea are usually mild; more severe signs need evaluation.
  
• If symptoms worsen or overlap with illness, our Beaumont emergency room can help assess your child safely.

When Does Teething Start

Teething usually begins between 4 and 7 months of age, although some babies may start earlier or later. The lower front teeth are often the first to erupt, followed by the upper front teeth. During this stage, increased drooling and gum inflammation are common and can make babies more irritable. 

A well-known study published in Pediatrics by the National Institutes of Health found that 92% of infants experienced drooling, while symptoms like true illness were not directly linked to teething.

How Long Does Teething Last

Teething is a long process that continues until about 2 to 3 years of age, when the last molars erupt. Each tooth can cause discomfort for several days before and after it breaks through the gums. Symptoms tend to come and go rather than remain constant. Most babies experience relief once the tooth fully emerges.

Symptoms Of Teething

• Excessive drooling.
  
• Chewing or biting on objects.
  
• Gum swelling or tenderness.
  
• Mild irritability or fussiness.
  
• Teething rash on the face due to saliva irritation.
  
• Slight temperature rise, not a true fever.

The Link Between Teething And Runny Nose

Teething and a runny nose often appear together because both occur during the same age range. Babies explore their environment by putting objects in their mouths, which can expose them to viruses. Drooling associated with teething may also be mistaken for nasal discharge. This overlap creates the perception of a connection rather than a direct cause.

Does Teething Cause Runny Nose

Teething does not directly cause a runny nose, but it can happen at the same time. Medical evidence shows that teething does not trigger nasal inflammation or mucus production. A runny nose while teething is more often related to minor viral infections or environmental irritation. If nasal discharge is thick, persistent, or accompanied by fever, another cause should be considered.

Why Do People Think Teething Causes a Runny Nose?

Many parents notice a runny nose and teething symptoms appearing during tooth eruption and naturally associate the two. This belief is reinforced by timing, increased drooling, and facial moisture. Babies also become more fussy and touch their faces more often during teething. These factors together can make normal illness symptoms seem teething-related.

• Increased Drooling: Excess saliva can spread around the mouth and nose, creating the appearance of a teething runny nose.
  
• Immune System Development: Babies encounter more viruses at this age, leading to teething and runny nose overlap.
  
• Facial Skin Irritation: Constant moisture can cause a teething rash or rash on the face when teething, adding to concern.

What Causes Runny Nose

A runny nose in babies is usually a normal response to irritation or infection. Infant nasal passages are sensitive and react easily to viruses, allergens, or dry air. Unlike teething, these triggers directly stimulate mucus production. Understanding the cause helps ensure proper care and avoids unnecessary worry.

• Viral Infections: The most common cause, especially colds picked up during early exploration.
  
• Allergies Or Irritants: Dust, smoke, or strong scents can irritate the nasal passages.
  
• Dry Or Cold Air: Environmental changes can increase nasal secretions.

When To See A Doctor?

Most teething symptoms are mild and manageable at home. However, some signs suggest illness rather than teething and need medical attention. Prompt evaluation helps rule out infection and keeps your child comfortable. Seek medical care if your child has:

• Fever above 100.4°F (38°C).
  
• Thick yellow or green nasal discharge.
  
• Persistent cough or difficulty breathing.
  
• Poor feeding or signs of dehydration.

If these symptoms appear, contact the Exceptional Emergency Centers for timely evaluation.

Treatment For Teething And Runny Nose

Managing teething and a runny nose focuses on comfort and symptom relief rather than medication. Gentle care can ease gum pain and reduce irritation from nasal discharge. Treatment depends on whether symptoms are teething-related or due to illness.

• Cold Teething Rings: Chilled (not frozen) teething rings help soothe gum inflammation and reduce teething discomfort safely.
  
• Teething Pain Medicine: Pediatrician-approved acetaminophen may be used for significant discomfort, following age-appropriate dosing guidelines.
  
• Saline Nose Drops: Saline drops help loosen nasal mucus and ease breathing during a runny nose while teething.
  
• Nasal Suction (Bulb Syringe or Aspirator): Gentle suction removes excess mucus, especially before feeding or sleep, improving comfort and airflow.
  
• Cool-Mist Humidifier: Moist air helps prevent nasal dryness and can ease congestion, particularly during sleep or in dry environments.
  
• Gentle Skin Care: Keeping the face clean and dry helps prevent teething rash on the face and irritation caused by drooling.
  
• Upright Positioning After Feeding: Keeping babies slightly upright after feeds supports nasal drainage and reduces mucus buildup.
  
• Hydration And Rest: Adequate fluids and rest support recovery and overall comfort during teething and minor illnesses.

Exceptional Emergency Centers For Pediatric Teething Care

Teething-related symptoms are often mild, but ongoing nasal discharge, breathing difficulty, or unusual behavior should never be ignored. At Exceptional Emergency Centers, families have access to immediate pediatric care when symptoms worsen or overlap with illness. Our experienced medical team evaluates infants and young children in a calm, child-friendly setting, ensuring timely care and peace of mind.

Wondering, can teething cause a runny nose, or if something more serious may be involved? While teething itself is rarely the cause, persistent congestion, fever, or feeding changes may signal infection or another concern. Exceptional Emergency Centers provide advanced pediatric care, clear diagnosis, and guidance on next steps to protect your child’s comfort, breathing, and overall health.
