Overview of Teething

Typical Age Range for Teething Onset

Most babies begin teething between 4 and 12 months, with the first tooth often appearing around 6 months. The teething process continues until about 2½ years old, when most children have a full set of 20 primary teeth. This period can be filled with excitement as you watch your infant’s smile change and grow.

Timeline and Sequence of Tooth Eruption

  • The middle bottom teeth (lower central incisors) are usually the first to appear.
  • Next, the middle 4 upper teeth (upper central incisors) erupt.
  • These are followed by lateral incisors, first molars, canines, and second molars.
  • By age 3, most children have all their baby teeth.

Each stage of baby teeth eruption can bring its own set of challenges, including gum pain and increased drooling as the teeth grow in.

Why Teething Is Often Misunderstood

Teething is often misunderstood because its timing overlaps with a period when babies are more prone to infections, such as ear infections or urinary tract infections. As infants lose the natural immunity they received from birth and begin exploring the world (and putting objects in their mouths), they are exposed to more germs. This overlap can make it difficult for parents to distinguish between teething symptoms and signs of illness, leading to the ongoing question: can teething cause fever?

Can Teething Cause Fever

Common Beliefs About Teething and Fever

Historical Context of the Fever-Teething Myth

For generations, it was widely believed that teething could cause high fevers, diarrhea, and other serious symptoms. This myth likely persisted because the timing of teething coincides with increased exposure to germs and a decrease in maternal antibodies, making infections more common during this stage.

How Misinformation Spreads

Misinformation about teething fever is often passed down through family advice, social media, and outdated resources. Even today, some products are marketed for “teething fever,” despite a lack of evidence that teething causes a true fever. This can be confusing for new parents searching for answers to “can teething cause fever.”

Cultural Perspectives on Teething Symptoms

In some cultures, teething is blamed for a wide range of infant illnesses, which can delay proper care for real infections. Gentle parenting advocates encourage evidence-based information, helping new parents understand what to expect and when to seek medical advice.

Understanding Teething Symptoms

Recognizing Genuine Teething Signs

While every infant is unique, the most common and scientifically supported teething symptoms include:

  • Sore, swollen gums: Gums may appear red, puffy, and tender where teeth are about to erupt.
  • Increased drooling: Excess saliva can lead to a rash on the chin or cheeks.
  • Irritability and fussiness: Babies may be crankier than usual, seeking extra comfort.
  • Chewing or gnawing on objects: Infants instinctively bite on teething rings, toys, or their own hands to relieve gum pain.
  • Mild sleep disturbances: Discomfort may cause more night waking or trouble settling.
  • Slightly elevated temperature: Teething can cause a minor rise in body temperature, but not a true fever (not above 100.4°F/38°C).

Symptoms Often Misattributed to Teething

It’s important to know which symptoms are not caused by teething, as these may indicate an infection or other health issue:

  • High fever (≥100.4°F/38°C): A true fever is almost always a sign of infection, not teething.
  • Diarrhea: There is no scientific evidence linking teething to diarrhea.
  • Runny nose, cough, vomiting: These symptoms are more likely due to a viral or bacterial infection.
  • Rash beyond the mouth/chin area: While drool may cause a facial rash, widespread rashes are not related to teething.

The Myth of Fever and Teething

Myths vs. Facts

For new moms and parents, the question “can teething cause fever” is a common concern. Research and expert consensus show that while teething may cause a slight rise in body temperature, it does not cause a true fever. Typical teething symptoms include mild irritability, gum pain, drooling, and a minor temperature increase, but a genuine fever (100.4°F/38°C or higher) is not caused by teething. This understanding is essential for gentle parenting and ensures your newborn or infant receives the right care.

According to the MedlinePlus Medical Encyclopedia on teething, teething may cause some discomfort but does not cause fever or diarrhea. If your infant develops a true fever, it’s important to look for other causes and consult your healthcare provider.

Pediatric Fever Definition

Pediatricians define fever in infants as a rectal temperature of 100.4°F (38°C) or higher. Teething may cause a low-grade temperature, but it does not meet this threshold. If your baby’s body temperature reaches or exceeds this level, it’s time to look for other causes, such as infection.

Evidence-Based Consensus

The clear answer to “can teething cause fever” is no. Any temperature at or above 100.4°F (38°C) is a sign to check for infection, not just teething. This distinction helps parents avoid missing serious conditions in their infants.

Why Babies Often Get Sick When Teething

Many parents notice their infants seem to get sick more often while teething. This is not because teething causes fever, but rather due to:

  • Waning maternal immunity: As babies grow, the natural immunity they received from birth decreases, making them more susceptible to infections like ear infections and urinary tract infections.
  • Increased exposure to germs: As babies’ teeth erupt and they explore with their mouths, they encounter more bacteria and viruses, raising the risk of infection.

Differentiating Fever Causes in Infants

When your infant develops a fever, ask yourself: can teething cause fever, or is something else going on? If your baby’s temperature is 100.4°F (38°C) or higher, consider other causes such as infection.

Common causes of fever in babies:

  • Viral infections (colds, flu, respiratory illnesses)
  • Bacterial infections (ear infections, urinary tract infections)
  • Vaccinations (can cause mild, short-lived fever)

Red flags—call your pediatrician if:

  • Fever of ≥100.4°F (38°C)
  • High or persistent fever
  • Loss of appetite for both solids and liquids
  • Lethargy or inconsolable crying
  • Widespread rash, vomiting, or diarrhea
  • Symptoms lasting more than a few days
  • Signs of dehydration or breathing difficulty

Safe Practices for Teething Relief

  • Gum massage: Gently rub your baby’s gums with a clean finger or wet gauze.
  • Teething rings: Use firm rubber teething rings (chilled, not frozen).
  • Avoid: Numbing gels, teething necklaces, homeopathic teething tablets, and honey (for babies under one year).
  • Medications: Use infant acetaminophen or ibuprofen only after consulting your pediatrician.

The FDA’s guidance on safely soothing teething pain recommends avoiding teething gels, homeopathic teething tablets, and teething necklaces due to potential safety risks, and instead suggests using gentle gum massage and firm rubber teething rings.
