Is it a Cold and Teething? How to Tell the Difference and Help Your Baby

If you are a parent, you have likely spent a midnight hour wondering why your little one is fussing. Is it that baby’s first tooth finally making an appearance, or is a pesky virus at play? Differentiating between a cold and teething can be surprisingly tricky because the symptoms often overlap. Both can cause a cranky baby, sleepless nights, and a fair amount of stress for the whole family.

Understanding the subtle nuances between common cold symptoms and the developmental milestone of tooth eruption is essential for providing the right care. In this guide, we will explore how to spot the signs of gum inflammation, manage a runny nose, and know exactly when it is time to seek professional paediatrician advice.

The Great Debate: Symptoms Comparison

While many parents believe teething causes systemic illness, research published on PubMed suggests that teething symptoms are generally localised to the mouth and face. A true fever in infants (a temperature over 38°C) is rarely caused by teething alone and is more likely a sign of an infection.

Below is a handy comparison to help you distinguish between the two conditions:

Symptom	Teething Signs	Cold Symptoms
Nasal Congestion	Rare; usually limited to clear moisture.	Common; thick or discoloured mucus.
Temperature	Mild “flushing” or very slight rise.	Often a high temperature (over 38°C).
Coughing	Occasional; usually due to excessive drooling.	Frequent; often sounds chesty or dry.
Drooling	Extremely common and heavy.	Uncommon, unless the throat is sore.
Sleep Patterns	Waking due to sore gums.	Waking due to nasal congestion.

Spotting the Signs of Teething

When a baby is teething, the primary source of discomfort is gum inflammation. As the tooth pushes through the periodontal tissue, it creates a dull ache. You might notice your baby constantly chewing on their fists or reaching for a teething ring to apply counter-pressure to the site.

According to the NHS, teething usually begins around six months, though it can start much earlier or later. Common signs include:

• Irritability in babies that peaks and ebbs throughout the day.
• Red, swollen, or bulging gums.
• A mild “teething rash” on the chin caused by excessive drooling.
• Changes in baby sleep patterns, typically difficulty settling.
• Loss of appetite for solid foods (sucking a bottle or breast might feel better).

If you suspect the pain is significant, you can explore Cochrane reviews for evidence-based natural teething remedies, such as chilled (not frozen) teething toys or gentle gum massage.

Identifying a Common Cold

A cold is a viral infection of the upper respiratory tract. Unlike teething, which is a localized physical process, a cold involves the immune system. The CDC notes that infants can have as many as eight to ten colds in their first two years as their immune systems mature.

Key indicators of a cold include:

1. Significant nasal congestion that makes breathing or feeding difficult.
2. Sneezing and a persistent cough.
3. A high temperature that may last for two or three days.
4. Decreased energy levels or lethargy.
5. Watery or red eyes.

The Cleveland Clinic emphasises that while a cold is usually harmless, it requires monitoring to ensure it doesn’t lead to secondary infections like earaches.

Can a Cold and Teething Happen at the Same Time?

The short answer is: Yes. In fact, they often do. Between six and 24 months, babies lose the maternal antibodies they were born with and start exploring the world by putting everything in their mouths. This “oral phase” is exactly when most teeth erupt, making the overlap of cold and teething very common.

Some experts theorise that the stress of teething might slightly weaken the immune response, or that the extra hand-to-mouth contact increases viral exposure. Regardless of the cause, managing both requires a double dose of patience and teething pain relief strategies.

Safe Relief for Your Little One

Whether it is a virus or a new molar, your goal is comfort. For teething pain relief, focus on cooling and pressure. A clean, damp flannel kept in the fridge can provide immense relief for sore gums. For a cold, using saline drops can help clear nasal congestion before feeds.

The Mayo Clinic advises against using teething gels containing benzocaine or lidocaine, as these can be harmful to infants. Instead, stick to physical comfort or paracetamol/ibuprofen if recommended by your pharmacist, especially if there is a fever in infants.

Remember to follow The Lullaby Trust guidelines for safe sleep, even when your baby is unwell. Avoid placing extra pillows or loose items in the cot to help them breathe better; instead, keep the room at a comfortable temperature.

When to Call the Doctor

While most cases of cold and teething can be managed at home, certain “red flags” require a call to your GP or health visitor. According to NICE guidelines, you should seek medical attention if:

• The baby is under 3 months old and has a temperature of 38°C or higher.
• There are signs of dehydration (fewer wet nappies, dry mouth).
• The baby has difficulty breathing or is wheezing.
• A rash appears that does not disappear when a glass is pressed against it (see St John Ambulance for meningitis signs).
• The irritability in babies becomes inconsolable or the baby is unusually drowsy.

For more general child health information, the World Health Organization and American Academy of Pediatrics offer extensive resources on developmental milestones and illness management.

Maintaining Oral Hygiene

Even before those teeth fully emerge, oral health is vital. The British Dental Association and the British Dental Health Foundation recommend brushing as soon as the first tooth breaks the surface. Use a tiny smear of fluoride toothpaste to protect that new enamel.

If you are ever unsure about a symptom, organisations like the British Red Cross offer first-aid apps and courses that can empower you to handle these common parenting hurdles with confidence.

Frequently Asked Questions (FAQs)

Can teething cause a runny nose?

While teething causes excessive drooling, it does not typically cause a thick or persistent runny nose. If the mucus is clear and very mild, it might be related to the facial irritation of teething, but a true “snotty” nose is almost always a sign of a viral common cold.

How long do teething symptoms last compared to a cold?

Teething discomfort usually lasts for a few days before and after the tooth breaks the gum. A cold typically peaks at day three or four and can linger for up to 10 to 14 days. If irritability in babies lasts longer than a week without a tooth appearing, it may be worth consulting a professional.

What is the best way to soothe a baby with both a cold and teething?

Focus on hydration and comfort. Offer plenty of fluids (milk or water), use a cool teething ring for sore gums, and utilise saline drops for nasal congestion. Plenty of skin-to-skin contact and cuddles are also scientifically proven to help lower stress levels for both parent and child.
