Teething may cause a slight rise in temperature, but true fever is uncommon and usually signals another issue.
Understanding Teething and Its Symptoms
Teething is a natural developmental process where babies’ primary teeth emerge through the gums. This milestone often triggers discomfort, irritability, and physical symptoms that can puzzle many parents. Among these concerns, the question “DO Babies Have Fever When Teething?” stands out as a common worry.
Babies typically begin teething around 4 to 7 months of age, although this can vary widely. The process continues until about age 3 when all 20 primary teeth usually have erupted. During this time, babies may drool excessively, chew on objects, and experience swollen or tender gums.
Parents often notice changes in behavior — fussiness, disrupted sleep patterns, and decreased appetite are frequent complaints. However, distinguishing between teething symptoms and signs of illness is crucial for caregivers.
Common Signs Linked to Teething
The physical effects of teething are mostly localized to the mouth area. These include:
- Gum swelling and redness: The gums become inflamed as the tooth pushes through.
- Increased drooling: Saliva production ramps up during teething.
- Mild irritability: Discomfort leads to crankiness or clinginess.
- Mild chewing or biting behavior: Babies try to relieve gum pressure by gnawing on toys or fingers.
These signs are generally mild and manageable. But when it comes to fever, things get murkier.
The Science Behind Fever and Teething
A fever is medically defined as a body temperature above 100.4°F (38°C). It’s a response by the immune system typically triggered by infection or inflammation. But does teething itself cause this spike in temperature?
Research indicates that while teething can cause a slight increase in body temperature (often called low-grade fever), it rarely leads to an actual fever. The irritation from the erupting tooth may induce mild inflammation localized in the gums but shouldn’t provoke systemic fever.
Several studies have monitored infants during teething phases and found no significant correlation between teething and high fevers. Instead, when babies display true fevers during this period, it’s often due to unrelated infections such as colds, ear infections, or other illnesses.
Mild Temperature Rise vs. Fever
It’s important to differentiate between a mild temperature increase and a genuine fever:
- Mild rise (below 100.4°F): Can occur due to increased blood flow in gums or minor inflammatory response; considered normal during teething.
- True fever (above 100.4°F): Typically signals infection; should prompt medical evaluation especially in infants under 6 months.
Parents sometimes mistake fussiness combined with warm skin for fever caused by teething alone. However, actual fevers warrant close attention.
Why Do Babies Often Get Sick While Teething?
Babies’ immune systems are still developing during the teething period, making them more vulnerable to common childhood illnesses like colds or flu viruses. This overlap in timing can create confusion about whether symptoms stem from teething or an infection.
Additionally, increased drooling during teething may lead babies to put more objects into their mouths. This behavior increases exposure to germs that cause respiratory or gastrointestinal infections.
Therefore, while teething itself isn’t a direct cause of high fever or serious illness, it coincides with an age when babies frequently encounter pathogens.
Signs That Fever Is Not From Teething
Recognizing when a baby’s fever is unrelated to teething is critical for timely treatment:
- High temperature (above 101°F): Unlikely caused by teething alone.
- Lethargy: Excessive sleepiness or difficulty waking up.
- Persistent crying inconsolable by typical soothing methods.
- Refusal to eat or drink fluids: Risk of dehydration increases with illness.
- Other symptoms such as coughing, vomiting, diarrhea: Indicate possible infection.
If these signs appear alongside fever during teething stages, consult a pediatrician promptly.
Treating Discomfort: Managing Teething Symptoms Safely
While you can’t stop teeth from coming in, there are safe ways to ease your baby’s discomfort without mistaking symptoms for illness.
Pain Relief Options for Teething Babies
- Cold objects: Chilled (not frozen) teethers or washcloths soothe inflamed gums effectively.
- Gentle gum massage: Using clean fingers to rub gums offers relief by counteracting pressure buildup.
- Avoid numbing gels containing benzocaine: These pose risks including methemoglobinemia and aren’t recommended for infants under two years.
- Pediatrician-approved pain relievers: Infant acetaminophen (Tylenol) may be used if discomfort interferes with feeding or sleeping; always follow dosage instructions carefully.
Creating a calm environment helps too—soft rocking motions and cuddling comfort your baby during this trying phase.
The Role of Temperature Monitoring During Teething
Keeping track of your baby’s temperature during suspected teething episodes helps distinguish normal symptoms from illness requiring medical attention.
The Best Ways To Take Baby’s Temperature
| Method | Description | Accuracy & Notes |
|---|---|---|
| Rectal Thermometer | A small digital thermometer inserted gently into the rectum. | The gold standard for accuracy in infants; recommended for babies under 3 months. |
| Tympanic (Ear) Thermometer | A device measuring infrared heat from the ear canal. | Quick but less accurate if not positioned correctly; suitable for older infants. |
| Axillary (Underarm) Thermometer | A thermometer placed under the baby’s arm against skin. | Easiest but least accurate; useful for screening but confirm with rectal if elevated reading occurs. |
Regularly checking temperatures when your baby seems uncomfortable allows you to respond appropriately without overreacting to normal fluctuations.
Navigating Parental Concerns: DO Babies Have Fever When Teething?
This question pops up everywhere—from parenting forums to pediatric visits—and understandably so! The worry about whether your little one’s fussiness signals something serious is natural.
Experts agree that while mild warmth may accompany gum irritation during tooth eruption, any significant fever points toward another cause. Being alert but not alarmed prevents unnecessary stress.
Trust your instincts: if your baby feels hot consistently above 100.4°F with other concerning symptoms like poor feeding or lethargy, seek medical advice without delay.
The Importance of Professional Guidance
Pediatricians rely on thorough assessments beyond just temperature readings—examining overall behavior and physical signs—to differentiate between routine teething discomfort and illness needing treatment.
Don’t hesitate to reach out if you feel unsure about your child’s condition—early intervention can prevent complications from infections that sometimes masquerade as “teething fevers.”
A Quick Reference: Symptoms Comparison Table During Teething vs Infection-Related Fever
| Symptom/Sign | Teething-Related Symptom | Disease-Related Fever Symptom |
|---|---|---|
| Mild Temperature Rise (<100.4°F) | Possible due to gum inflammation; short-lived increase common. | No; temperatures usually higher with infections. |
| Irritability/Fussiness | Mild irritability typical around eruption times. | Loud crying inconsolable; extreme irritability common with illness. |
| Drooling & Chewing Behavior | Pervasive due to gum discomfort; normal part of process. | No direct connection; drooling not typical symptom of most infections. |
| Lethargy & Poor Feeding | No significant lethargy; appetite might dip slightly from discomfort only. | Lethargy common; refusal to eat/drink signals illness severity. |
| Coughing/Sneezing/Runny Nose | No associated respiratory symptoms from teething alone. | Presents frequently alongside infectious fevers (cold/flu). |
| Date Range | Sporadic episodes aligned with tooth eruption timelines (months). | No relation to eruption timing; any age possible depending on exposure/infection type. |

Frequently Asked Questions
Do Babies Have Fever When Teething?
Babies may experience a slight rise in temperature during teething, but a true fever above 100.4°F (38°C) is uncommon. If a baby has a high fever, it usually indicates an infection or another illness rather than teething itself.
Can Teething Cause a Mild Temperature Increase in Babies?
Teething can cause a mild increase in body temperature due to localized gum inflammation. This low-grade rise is typically below the fever threshold and should not be mistaken for an actual fever caused by illness.
How Can Parents Tell If Babies Have Fever When Teething or Sick?
Parents should monitor the baby’s temperature carefully. A mild temperature rise may occur with teething, but if the baby shows other symptoms like persistent high fever, rash, or lethargy, it’s more likely due to an infection requiring medical attention.
Why Do Some Parents Think Babies Have Fever When Teething?
Teething symptoms such as irritability, disrupted sleep, and drooling often coincide with mild temperature increases, leading parents to associate these signs with fever. However, true fever is rare during teething and usually signals another health issue.
When Should Parents Be Concerned About Fever During Baby’s Teething?
If a baby develops a temperature above 100.4°F (38°C) or shows signs of illness like vomiting, diarrhea, or difficulty breathing, parents should seek medical advice. Such symptoms are unlikely caused by teething and may require treatment.
Conclusion – DO Babies Have Fever When Teething?
To sum it up: true fevers aren’t typical results of teething itself. While babies might show slight rises in body temperature due to gum irritation during tooth eruption phases, anything above 100.4°F usually signals an underlying illness rather than just growing teeth.
Parents should monitor their child closely—using proper thermometers—and watch for additional warning signs such as lethargy, poor feeding, persistent crying, or respiratory symptoms that indicate infection rather than simple teething distress.
By understanding these nuances clearly and responding wisely with comfort measures plus medical support when needed, caregivers can confidently navigate those challenging months without unnecessary worry over “teething fevers.”
Remember: mild fussiness and drooling? Normal parts of growing up! High temp plus other concerning signs? Time for professional care!
