Teething may cause a slight temperature rise but does not directly cause true fevers above 100.4°F (38°C).
Understanding Teething and Its Symptoms
Teething is a natural process where an infant’s primary teeth push through the gums. This milestone usually begins around six months of age but can vary widely among babies. It’s a time filled with new sensations and sometimes discomfort, leading to common symptoms like drooling, gum swelling, irritability, and disrupted sleep.
One question parents often ask is: Does teething cause fevers? The answer isn’t straightforward because while many babies experience mild temperature elevations during teething, a genuine fever—defined as a body temperature over 100.4°F (38°C)—is rarely caused by teething alone.
The gum irritation and inflammation from a tooth breaking through can cause slight warmth or flushed cheeks. However, if your baby has a high fever or other concerning symptoms like lethargy or vomiting, it’s important to look for other causes such as infections.
Why Do Parents Think Teething Causes Fevers?
Babies often develop their first teeth around the same time their immune systems are still maturing. This period coincides with increased exposure to viruses and bacteria. When infants catch colds or other infections, they develop fevers. Since these illnesses often happen simultaneously with teething, it’s easy to assume the two are directly linked.
In reality, the mild discomfort from teething can make babies fussier and less able to fight off infections effectively. Plus, excessive drooling and putting objects in their mouths can introduce germs, increasing infection risk.
The Science Behind Fever and Teething
A fever is the body’s natural defense mechanism against infection. It raises the internal temperature to create an environment less hospitable to viruses and bacteria while boosting immune response.
Teething causes localized inflammation in the gums but doesn’t trigger systemic immune responses strong enough to cause high fevers. Research shows that any rise in temperature during teething is usually minimal—often under 100.4°F (38°C), which is considered low-grade or no fever at all.
One study observed infants during active teething phases and found no significant difference in core body temperatures compared to non-teething periods. Mild temperature increases can result from irritation or minor inflammation but are not true fevers caused by infection.
How To Differentiate Teething Symptoms From Fever
It’s essential for caregivers to recognize when a baby’s symptoms indicate something more serious than just teething discomfort:
- Temperature: A slight increase below 100.4°F may be related to teething; anything higher suggests infection.
- Behavior: Mild fussiness is normal; extreme irritability, lethargy, or poor feeding needs medical attention.
- Other symptoms: Runny nose, cough, vomiting, diarrhea—signs of illness rather than teething.
If your child has a high fever that lasts more than a day or other worrying signs, consult your pediatrician promptly.
Common Signs Accompanying Teething
Besides the potential for slight temperature rises, here are typical signs associated with teething:
- Gum swelling and redness: The area where the tooth will emerge often looks inflamed.
- Drooling: Increased saliva production can lead to skin irritation around the mouth.
- Biting and chewing: Babies try to relieve pressure by gnawing on toys or fingers.
- Mild irritability: Discomfort may disrupt sleep patterns temporarily.
These symptoms vary widely between infants; some hardly notice teething while others show clear signs of distress.
The Role of Inflammation During Teething
Inflammation is part of the body’s healing process when teeth push through gums. It causes redness and tenderness but remains localized without triggering systemic fever responses.
The gum tissue releases inflammatory chemicals like prostaglandins that cause swelling and sensitivity but don’t elevate overall body temperature significantly.
Treatment Options for Teething Discomfort
Relieving your baby’s discomfort during teething involves soothing irritated gums safely:
- Cold items: Chilled (not frozen) teethers or washcloths help numb gums.
- Massage: Gently rubbing gums with clean fingers provides relief.
- Pain relief meds: Infant acetaminophen or ibuprofen may be used under doctor guidance if pain disrupts sleep or feeding.
Avoid using topical numbing gels containing benzocaine as they pose risks for infants.
The Importance of Hygiene During Teething
Since babies tend to put everything into their mouths during this phase, keeping items clean reduces infection risk that could cause genuine fevers:
- Regularly sanitize teethers and toys.
- Avoid exposure to sick individuals.
- Wash hands frequently after diaper changes or before feeding.
Good hygiene helps prevent illnesses that might be mistaken as “teething fevers.”
A Closer Look: Temperature Variations in Teething Babies
| Temperature Range (°F) | Description | Possible Cause During Teething |
|---|---|---|
| <99°F (37.2°C) | Normal/No Fever | Mild gum irritation; no systemic response |
| 99-100.4°F (37.2-38°C) | Slightly Elevated Temperature | Mild inflammation from teething; not true fever |
| >100.4°F (38°C) | Fever Present | Likely infection or illness unrelated directly to teething |
This table summarizes typical temperature readings seen in infants around teething time and helps clarify when medical evaluation is necessary.
The Link Between Teething And Illness: Coincidence Or Cause?
It’s common for babies to catch viral infections during the age window when they start teething because their immune systems are still developing. This overlap leads many parents to connect fevers directly with tooth eruption.
However, most pediatricians agree that while mild discomfort from teething can slightly raise body temperature temporarily, persistent high fevers almost always point toward an underlying illness such as:
- Common cold or flu viruses;
- Ear infections;
- Croup;
- Other bacterial infections requiring treatment.
Recognizing this distinction prevents delayed diagnosis of illnesses needing medical care.
The Impact of Misattributing Fevers To Teething
Assuming all fevers stem from teething risks overlooking serious conditions early on. Delays in seeking treatment could worsen outcomes for infants who develop infections requiring antibiotics or hospitalization.
Parents should monitor symptoms carefully: if fever persists beyond 24 hours or worsens despite comfort measures—or if accompanied by unusual behavior—professional advice should be sought immediately.
Tackling Myths About Does Teething Cause Fevers?
Numerous myths surround teething and fever links:
- “Teeth coming in cause high fevers”: No scientific evidence supports this claim; high fevers signal illness.
- “All fussiness means teeth pain”: Babies cry for many reasons including hunger, tiredness, infections—not just teeth pain.
- “Drooling causes fever”: This is false; drooling doesn’t affect internal body temperature but may irritate skin externally.
Understanding facts helps parents respond appropriately instead of worrying unnecessarily.
Taking Care Of Your Baby During Teething And Fever Episodes
If your baby shows signs of both teething discomfort and elevated temperature under 100.4°F:
- Keeps them hydrated with breast milk or formula;
- Soothe gums with cold teethers;
- Mild pain relievers under doctor guidance;
- Avoid overdressing as overheating can raise body temps;
- Create calm environments promoting rest;
If temperatures rise above 100.4°F or other symptoms appear—such as rash, vomiting, persistent crying—seek medical care promptly rather than assuming it’s just teething.

Frequently Asked Questions
Does Teething Cause Fevers Above 100.4°F?
Teething may cause a slight temperature rise but does not directly cause true fevers above 100.4°F (38°C). Any higher fever is likely due to an infection or other illness, not teething itself.
Why Do Parents Think Teething Causes Fevers?
Parents often associate fevers with teething because babies start teething when their immune systems are still developing. During this time, infections are common, which can cause fevers unrelated to teething.
Can Teething Cause Any Temperature Increase?
Teething can cause mild gum inflammation and localized warmth, sometimes leading to a slight temperature increase. However, this rise is usually minimal and not considered a true fever.
How Can I Tell If My Baby’s Fever Is From Teething?
If your baby’s temperature exceeds 100.4°F or is accompanied by symptoms like lethargy or vomiting, it’s unlikely caused by teething. Consult a healthcare provider to rule out infections or other causes.
What Are Common Symptoms of Teething Besides Fever?
Common teething symptoms include drooling, gum swelling, irritability, and disrupted sleep. These signs reflect gum discomfort but do not typically involve high fever or severe illness.
Conclusion – Does Teething Cause Fevers?
In summary, while mild temperature rises can accompany the gum inflammation caused by emerging teeth, true fevers above 100.4°F (38°C) are generally not caused by teething itself. Most high fevers indicate an underlying infection needing medical attention rather than simple tooth eruption discomfort.
Parents should carefully observe their child’s behavior alongside any temperature changes and treat minor symptoms with gentle remedies like cold teethers or appropriate pain relievers under guidance. Vigilance ensures that real illnesses don’t get mistaken for normal developmental phases like teething.
Understanding this distinction means better care decisions and peace of mind during those challenging early months filled with new milestones—and yes—those first wobbly little teeth!
