Teething may cause a mild temperature rise but does not typically lead to high fevers over 101°F (38.3°C).
Understanding Teething and Its Symptoms
Teething is a natural developmental phase where infants’ primary teeth break through the gums. It usually begins around six months of age but can vary widely, sometimes starting as early as three months or as late as twelve months. This process can be uncomfortable, causing symptoms that worry many parents. Common signs include drooling, irritability, gum swelling, and a tendency to chew on objects.
One question that pops up frequently is about fevers during teething. Parents often notice their babies feeling warmer than usual and wonder if teething is the culprit behind high fevers. It’s crucial to differentiate between a mild rise in body temperature due to teething and a true fever indicating an infection or illness.
Can Teething Cause High Fevers? Exploring the Evidence
The short answer is no—teething itself does not cause high fevers. While it’s common for babies to experience slight temperature elevations during teething, these are typically low-grade fevers below 101°F (38.3°C). High fevers—those above this threshold—are usually signs of something else going on, such as viral or bacterial infections.
Medical research supports this distinction. Studies have shown that while infants may appear flushed or warm during teething episodes, their core body temperature rarely reaches levels considered a significant fever. The inflammation around the gums can cause discomfort and minor systemic effects but doesn’t trigger the body’s fever response in the same way infections do.
Why Do Parents Mistake Teething for High Fever?
It’s easy to confuse teething symptoms with illness because many signs overlap:
- Irritability: Both teething and infections can make babies fussy.
- Increased drooling: Teething causes excessive drooling, which might lead to skin irritation mistaken for illness.
- Mild temperature elevation: Slight warmth can be misread as a fever.
- Changes in feeding or sleeping patterns: Discomfort from teething can disrupt routines.
Because infants cannot communicate their feelings clearly, parents understandably worry when their child feels warm and unsettled. However, it’s important to use an accurate thermometer reading rather than relying on touch alone.
The Biological Mechanism Behind Teething and Temperature Changes
Teething involves localized inflammation in the gums where teeth push through soft tissue. This inflammation triggers the release of certain chemicals called prostaglandins and cytokines, which can slightly raise body temperature. However, this reaction is mild compared to systemic infections that activate the hypothalamus—the brain’s temperature regulation center—to induce fever.
The inflammation during teething is limited to the mouth area and doesn’t spread throughout the body like an infection would. That’s why any temperature increase tends to be minimal and transient.
Typical Temperature Range During Teething
Most infants experience temperatures between 99°F (37.2°C) and 100.4°F (38°C) while teething. These readings fall under what doctors call “low-grade” or “subfebrile” temperatures—not true fevers requiring medical intervention.
Here is a table summarizing typical temperature responses related to teething compared with common infant illnesses:
| Condition | Usual Temperature Range | Common Symptoms |
|---|---|---|
| Teething | 99°F – 100.4°F (37.2°C – 38°C) | Mild gum swelling, drooling, irritability |
| Viral Infection (e.g., cold) | 100.4°F – 102°F (38°C – 38.9°C) | Coughing, congestion, lethargy |
| Bacterial Infection (e.g., ear infection) | >102°F (>38.9°C) | Pain, persistent high fever, fussiness |
Differentiating Between Teething Fever and Illness Fever
Parents need clear guidelines for when elevated temperatures are cause for concern beyond teething discomfort:
- Duration: A mild rise in temperature lasting less than 24 hours may be linked to teething.
- Severity: Temperatures above 101°F (38.3°C) are unlikely caused by teething alone.
- Add-on symptoms: Presence of vomiting, diarrhea, rash, lethargy, or difficulty breathing suggests illness.
- Behavior changes: Excessive crying that doesn’t improve with soothing or signs of pain unrelated to gums require evaluation.
If your baby shows persistent high fever or additional symptoms like poor feeding or dehydration signs (dry mouth, fewer wet diapers), medical attention should be sought promptly.
The Role of Infections During Teething Periods
Infants often start encountering new germs around the same age they begin teething due to increased hand-to-mouth activity and exposure at daycare or playgroups. This coincidence sometimes leads parents to wrongly blame teeth eruption for symptoms actually caused by infections.
For example:
- Upper respiratory infections: Common colds cause higher fevers than teething ever would.
- Ear infections: These often occur simultaneously with teething but require antibiotics.
- Canker sores or thrush: Oral infections might worsen gum discomfort but are distinct conditions.
Recognizing these differences ensures babies receive timely treatment instead of just comfort measures for presumed teething issues.
Treating Discomfort Without Misinterpreting Fever Causes
Managing your baby’s pain during tooth eruption focuses on soothing irritated gums rather than fever reduction unless truly needed.
Here are safe options:
- Cold objects: Chilled (not frozen) teethers help numb sore gums effectively.
- Gentle gum massage: Using clean fingers can relieve pressure points.
- Pain relievers: Infant acetaminophen or ibuprofen may be used under pediatric guidance if discomfort affects feeding or sleep.
- Avoid topical anesthetics: Many over-the-counter gels contain benzocaine which isn’t recommended for infants due to potential side effects.
If your child develops a high fever alongside other worrying symptoms, don’t hesitate to consult a healthcare provider rather than attributing everything solely to teething.
The Importance of Accurate Temperature Measurement
Taking your baby’s temperature correctly helps avoid unnecessary panic over “fever.” Rectal thermometers provide the most accurate readings in infants under three years old; oral thermometers aren’t reliable at this age.
Avoid guessing by touch alone—skin warmth doesn’t always reflect internal body temperature accurately.
The Science Behind Why Can Teething Cause High Fevers? Is It Myth or Fact?
Despite widespread beliefs linking high fevers directly with tooth eruption, pediatricians consistently report no causal relationship between severe fever spikes and teething alone.
A landmark study published in Pediatrics examined hundreds of infants during their primary tooth eruption phases and found no significant correlation between severe febrile episodes and timing of tooth emergence.
The myth likely stems from coincidental timing: many childhood illnesses peak around six months when babies also start cutting teeth.
Understanding this distinction helps prevent delayed diagnosis of potentially serious infections mistakenly blamed on normal developmental milestones like teething.
The Impact of Misdiagnosis on Infant Health Care
Misattributing high fevers solely to teething can lead parents down dangerous paths:
- Treatment delays: Serious infections might go untreated if parents assume it’s just “teeth coming in.”
- Anxiety escalation: Repeated unexplained fevers cause stress without proper medical guidance.
- Avoidance of necessary care: Hesitating to seek help increases risk of complications from illnesses like ear infections or pneumonia.
Healthcare professionals emphasize vigilance during this vulnerable period while reassuring families about what symptoms truly signal emergency versus normal growth processes.
Navigating Parental Concerns: Practical Advice For Monitoring Symptoms During Teething
Parents juggling sleepless nights with fussy babies need clear strategies:
- Create a symptom diary: Track temperatures alongside behaviors daily; patterns help differentiate causes over time.
- Avoid self-medicating unnecessarily: Use medications only when recommended by pediatricians based on confirmed fevers above threshold levels.
- Keen observation for additional signs: Look beyond gum discomfort—runny nose, coughs, rashes require attention too.
- Cultivate calm reassurance: Understand that some fussiness is normal but persistent distress warrants professional input.
This approach empowers caregivers with knowledge rather than fear-driven assumptions about “high fevers” linked directly with teeth eruption.

Frequently Asked Questions
Can Teething Cause High Fevers in Babies?
Teething may cause a mild increase in temperature but does not typically lead to high fevers above 101°F (38.3°C). High fevers are usually caused by infections or illnesses, not the teething process itself.
Why Does Teething Sometimes Seem to Cause a Fever?
During teething, localized gum inflammation can cause slight temperature elevations. However, this mild warmth is not the same as a true fever and rarely exceeds low-grade levels.
How Can Parents Tell if a Fever Is Caused by Teething?
Parents should use a thermometer to measure their baby’s temperature accurately. Fevers above 101°F (38.3°C) likely indicate an infection rather than teething and require medical attention.
What Symptoms Accompany Teething Besides Temperature Changes?
Common teething symptoms include drooling, irritability, gum swelling, and chewing on objects. These signs can overlap with illness symptoms, making it important to monitor temperature carefully.
When Should I Be Concerned About a Fever During Teething?
If your baby has a high fever over 101°F (38.3°C), persistent irritability, or other signs of illness, it’s best to consult a healthcare provider. High fevers are not typical of teething alone.
The Bottom Line – Can Teething Cause High Fevers?
Teeth erupting through tender gums can make babies cranky and cause slight rises in body temperature—but they do not trigger high fevers by themselves. True fevers exceeding 101°F signal underlying illness needing evaluation beyond typical teething discomforts.
Parents should focus on accurate measurement methods combined with close monitoring for additional symptoms indicating infection rather than attributing all distress solely to teeth cutting through gums.
By separating fact from myth regarding “Can Teething Cause High Fevers?” families gain peace of mind knowing when comfort measures suffice and when prompt medical care becomes essential for their little ones’ health and safety.
