Does Teething Lead To Fever?

Posted: February 25, 2025

Teething is an exciting yet challenging milestone for parents and babies alike. It signals your baby's growth, but it often comes with discomfort and confusion.

One common concern parents face is the question, can teething cause fever? While teething is often blamed for fevers, there’s more to the story.

Let’s explore the relationship between teething and fever, separate myths from facts, learn when your child should visit the dentist, and provide actionable advice to make this phase smoother for you and your baby in this My Teeth and Me guide.

Understanding Teething

Teething is the process where an infant's teeth start emerging through the gums, usually around six months of age. While this is an exciting time for parents, it can also be a challenging period due to the discomfort and distress that teething can cause for babies.

Some babies sail through the process with barely a fuss, while others might experience noticeable irritability and physical changes.

What is Teething?

Teething refers to the eruption of primary teeth, often called “baby teeth,” through the gum line. The process usually begins when a baby is between 4 to 7 months old, although the exact timing varies for each child.

Most children will have a full set of 20 primary teeth by the age of three. The first teeth to appear are typically the lower central incisors, followed by the upper central incisors. This process is gradual and continues until all baby teeth are in place.

Common Teething Symptoms

  • Increased drooling
  • Irritability
  • Chewing on objects
  • Swollen gums
  • Trouble sleeping

Teething and Fever: A Complex Relationship

The question of whether teething can cause fever has puzzled parents and healthcare professionals for years. While it is tempting to attribute every new symptom to teething, it’s essential to separate fact from fiction when addressing this concern.

Can Teething Cause Fever?

The idea that teething causes fever has been widely debated, but pediatric experts generally agree that teething does not directly cause a fever.

If your baby has a temperature higher than 100.4°F (38°C), it is more likely due to an unrelated illness, such as a mild viral infection.

Mild inflammation of the gums during teething can cause slight warmth, but it is not enough to elevate the body’s core temperature to the level of a true fever.

The Myth of Teething Fever

The belief that teething leads to fever has been passed down through generations, often supported by anecdotal observations from parents.

However, studies show that while teething can cause local gum irritation and discomfort, it does not trigger the immune response necessary to produce a full-body fever.

Other symptoms, such as a runny nose or diarrhea, are also commonly misattributed to teething but are more likely signs of a coinciding illness.

Why Fever is Not a Typical Teething Symptom

Teething primarily affects the gums and mouth, leading to localized symptoms like swelling and soreness. Fever, on the other hand, involves the entire body and typically occurs when the immune system is fighting off an infection.

The absence of systemic changes during teething further supports the conclusion that teething is unlikely to cause a fever.

When to Worry About a Fever 

It is important for parents to remain vigilant and distinguish between typical teething symptoms and signs of a more serious condition.

If your baby develops a high fever, appears unusually lethargic, or has additional concerning symptoms such as a persistent rash or difficulty breathing, consult a pediatrician promptly.

While teething might coincide with illness, it should not be considered the primary cause of fever or other severe symptoms.

Other Common Teething Discomforts

Drooling

Teething often stimulates excessive saliva production. While it’s harmless, constant drooling can lead to a mild rash around the mouth, chin, or neck.

Irritability and Fussy Behavior

The pressure of emerging teeth against the gums can make babies cranky. You might notice your little one crying more frequently or having trouble settling down.

Changes in Eating and Sleeping Patterns

Teething pain can disrupt normal routines. Babies may refuse food or wake up more frequently at night due to discomfort.

Mild Gum Inflammation and Soreness

Swollen, tender gums are a hallmark of teething. You may notice redness or small bumps where the teeth are about to emerge.

Soothing Teething Discomfort

Teething Rings

Chewing on a teething ring can provide gentle pressure to soothe aching gums. Opt for BPA-free rings for safety.

Cold Foods

Cold items, like chilled cucumber slices or yogurt, can numb sore gums and reduce inflammation. Avoid frozen items that can be too hard.

Over-the-Counter Pain Relievers

If your baby is particularly uncomfortable, infant acetaminophen or ibuprofen may help. Always consult a doctor for the correct dosage.

Gentle Massage

Rubbing your baby’s gums with a clean finger can offer immediate relief. Use circular motions for the best results.

When to Consult a Pediatrician

Persistent Diarrhea or Vomiting

While drooling can cause loose stools, consistent diarrhea or vomiting should be evaluated by a doctor.

Signs of Infection

Swelling, redness, or pus around the gums could indicate an infection requiring prompt care.

Unusual Symptoms

If your child appears lethargic, has difficulty breathing, or exhibits other alarming signs, seek help right away.

Promoting Oral Health During Teething

Gentle Brushing

Start cleaning your baby’s teeth as soon as they appear. Use a soft, baby-friendly toothbrush and water.

Fluoride-Free Toothpaste

For infants under two, fluoride-free toothpaste is recommended to protect their developing teeth and gums.

Regular Dental Check-ups

Schedule your baby’s first dental visit by their first birthday at My Teeth and Me. Early check-ups establish a strong foundation for oral health.

Mythbusting Teething Myths

Teething and Rashes

Drooling-related rashes are common, but they’re not directly caused by teething. Keeping the area dry can help.

Teething and Diarrhea

While drooling might loosen stools, frequent diarrhea is likely due to another cause and should be checked by a doctor.

Promoting Healthy Teething Habits

Breastfeeding and Bottle-Feeding

Breast milk provides comfort and nutrients during teething. Avoid prolonged bottle-feeding to prevent tooth decay.

Pacifier Use

Pacifiers can soothe babies, but overuse might affect tooth alignment. Gradually limit their use after teething.

Teething Toys

Invest in safe, age-appropriate teething toys. Clean them regularly to prevent bacteria buildup.

Additional Tips for Parents

Be Patient and Understanding

Remember, teething is temporary. Your calm and supportive demeanor can ease your baby’s discomfort.

Create a Calming Environment

A quiet, dimly lit room can help soothe a fussy baby. Soft music or white noise may also be comforting.

Offer Comfort and Reassurance

Sometimes, all your baby needs is a cuddle. Holding and rocking them can make a world of difference.

Teething Rash

Excessive drooling during teething can lead to rashes around the mouth and neck. Apply a thin layer of barrier cream, like petroleum jelly, to protect the skin. Regularly wipe drool with a soft, clean cloth.
