Teething may cause a slight rise in temperature, but it does not cause high fever or serious illness.
Understanding the Teething Process and Body Temperature
Teething is a natural developmental milestone in infants, typically starting around 6 months of age. As baby teeth push through the gums, many parents notice changes in their child’s behavior and health. One common concern is whether teething triggers high fever.
During teething, mild discomfort and irritation are expected. The gums become inflamed as teeth break through, causing fussiness, drooling, and sometimes a slight increase in body temperature. This mild temperature elevation is usually under 100.4°F (38°C) and should not be confused with a high fever.
High fever refers to temperatures above 101°F (38.3°C) and often signals infection or illness rather than teething itself. While it’s tempting to attribute all symptoms to teething, medical experts emphasize that significant fever should prompt evaluation for other causes.
Why Does Teething Cause Mild Temperature Rise?
The process of tooth eruption involves localized inflammation in the gums. This inflammation can slightly raise the body’s core temperature as part of the immune response. When tissues are irritated or swollen, blood flow increases to the area, which can cause a subtle systemic effect.
Saliva production also ramps up during teething, which may lead to minor throat irritation or diaper rash from drooling but does not directly cause fever.
It’s important to note that this mild temperature rise is transient and typically resolves on its own within a day or two without other symptoms like lethargy or poor feeding.
The Difference Between Mild Temperature and High Fever
Mild temperature elevation due to teething usually stays below 100.4°F (38°C). It often fluctuates slightly during the day but doesn’t spike suddenly or persist for more than 24-48 hours.
High fever, on the other hand:
- Is generally above 101°F (38.3°C)
- May last longer than two days
- Is often accompanied by other symptoms like cough, diarrhea, irritability, or rash
Recognizing this difference helps parents decide when to seek medical advice instead of attributing all signs to teething alone.
Common Symptoms Associated with Teething
Besides mild temperature elevation, teething can cause several noticeable signs:
- Gum swelling and tenderness: The gums become red and sore where teeth are emerging.
- Increased drooling: Excess saliva production can cause skin irritation around the mouth.
- Irritability: Babies may be fussy due to gum discomfort.
- Chewing behavior: Infants often bite or gnaw on objects to relieve pressure.
- Sleeplessness: Discomfort might disrupt normal sleep patterns temporarily.
None of these symptoms include severe systemic illness signs such as persistent high fever, vomiting, or diarrhea.
The Risks of Misattributing High Fever to Teething
Assuming that any fever is caused by teething can delay diagnosis of potentially serious infections like ear infections, respiratory illnesses, or gastroenteritis.
Health professionals caution against overlooking high fevers in infants because:
- Infections require timely treatment: Untreated infections can worsen rapidly in young children.
- Meningitis risk: High fever with lethargy and irritability could indicate dangerous conditions needing urgent care.
- Pediatric evaluation is essential: A doctor can differentiate between viral illness and benign teething symptoms.
Parents should monitor their child closely when fever exceeds 101°F (38.3°C) or lasts longer than two days.
When To Call a Doctor
Seek medical attention if your infant has:
- A fever over 101°F (38.3°C) lasting more than 48 hours
- Difficulties breathing or persistent coughing
- Poor feeding or dehydration signs such as dry mouth and fewer wet diapers
- Lethargy or unresponsiveness
- A rash accompanying the fever
These symptoms are unlikely caused solely by teething and warrant professional assessment.
The Science Behind Teething and Fever: What Studies Say
Numerous studies have investigated whether teething causes significant fevers. Research consistently shows that while minor temperature elevations are common during tooth eruption phases, true high fevers are not directly linked to teething.
For example:
- A study published in Pediatrics found no significant association between teething and high-grade fevers above 102°F (38.9°C).
- The American Academy of Pediatrics states that although mild temperature rises may occur with teething, any high fever should be evaluated for other causes.
- A review in The Journal of Family Practice concluded that attributing serious illness symptoms solely to teething risks missing critical diagnoses.
These findings reinforce caution against assuming all fevers during infancy are related to dental development alone.
Treating Teething Discomfort Without Mistaking Fever Symptoms
Managing typical teething discomfort involves simple remedies aimed at soothing irritated gums:
- Cold objects: Chilled (not frozen) teethers provide relief by numbing gum tissue.
- Gentle gum massage: Using a clean finger to rub gums can ease soreness.
- Pain relief medications: Acetaminophen or ibuprofen may be used under pediatric guidance for moderate pain.
- Keeps baby hydrated: Sufficient fluids help soothe overall discomfort.
If your child develops a true fever above 101°F (38.3°C), consult your pediatrician before administering medications targeted at infection rather than just pain relief.
Avoiding Common Mistakes With Teething Remedies
Some parents resort to outdated treatments like topical gels containing benzocaine or home remedies lacking evidence. These carry risks such as allergic reactions or toxicity in infants.
Stick with safe practices recommended by healthcare providers:
- No benzocaine gels for children under two years old due to risk of methemoglobinemia.
- Avoid aspirin because it’s linked with Reye’s syndrome in children.
- No herbal supplements without pediatric approval.
Proper treatment focuses on comfort while monitoring for signs beyond normal teething symptoms.
The Role of Immune System Changes During Infancy
Infants’ immune systems are still developing during the first year of life. This makes them more prone to infections coinciding with the typical age range for teething.
Babies explore environments orally; drooling increases exposure to germs from hands and objects. This overlap means illnesses causing fevers often occur around the same time as tooth eruption but remain unrelated causes.
Understanding this helps clarify why some parents mistakenly link high fevers directly with teething when another infection might be responsible instead.
A Detailed Comparison Table: Teething vs Fever Causes in Infants
| Symptom/Sign | Teething-Related Effects | Fever Due To Illness Causes |
|---|---|---|
| Mild Temperature Elevation | Slight increase below 100.4°F (38°C) | Sustained temperature over 101°F (38.3°C) |
| Irritability & Fussiness | Mild irritability from gum soreness; short duration | Irritability plus lethargy; prolonged discomfort |
| Drooling & Chewing Behavior | Excess saliva; biting objects relieves pain | No direct relation; drooling uncommon |
| Addition of Other Symptoms | No vomiting, diarrhea, rash | Coughing, vomiting, diarrhea, rash often present |
| Treatment Approach | Pain relief via cold objects & gum massage | Treat underlying infection; possible antibiotics |
| Pediatric Attention Needed? | No unless high fever develops | Yes if fever persists>48 hours or worsens |
The Emotional Toll on Parents During Teething Episodes With Fever Concerns
Seeing a baby uncomfortable is tough enough without worrying about what’s causing their distress. When a baby has both fussiness from teething plus an elevated temperature beyond normal limits, anxiety spikes for caregivers.
Parents need clear guidance on what signs require urgent care versus typical developmental discomforts. Misunderstanding this overlap leads many families down stressful paths involving unnecessary emergency visits or delayed treatment for real illnesses.
Healthcare providers encourage open communication so parents feel empowered recognizing red flags versus normal behavior changes during tooth eruption phases.

Frequently Asked Questions
Does Teething Cause High Fever in Babies?
Teething may cause a slight rise in temperature, but it does not cause high fever. High fever, typically above 101°F (38.3°C), is usually a sign of infection or illness rather than teething itself.
Why Does Teething Cause a Mild Temperature Increase?
The mild temperature rise during teething is due to localized inflammation in the gums. This inflammation triggers an immune response that can slightly elevate the body’s core temperature temporarily.
How Can You Tell If a Fever Is Caused by Teething?
A mild temperature under 100.4°F (38°C) may be related to teething. However, if the fever is higher or lasts more than two days, it’s important to consider other causes and seek medical advice.
Are There Other Symptoms Alongside Fever When Teething?
Besides a slight temperature rise, teething often causes gum swelling, tenderness, increased drooling, and fussiness. These symptoms are generally mild and temporary compared to signs of illness.
When Should You See a Doctor for Fever During Teething?
If your baby develops a high fever above 101°F (38.3°C), persistent fever lasting over two days, or additional symptoms like cough or rash, you should consult a healthcare professional promptly.
Conclusion – Does Teething Cause High Fever?
In summary, does teething cause high fever? The answer is no—teething itself may bring about slight increases in body temperature but does not cause true high-grade fevers exceeding 101°F (38.3°C). If your infant develops a significant fever alongside other concerning symptoms such as lethargy, vomiting, cough, or rash, seek medical advice promptly as these signs indicate an underlying illness rather than just tooth eruption discomfort.
Recognizing this distinction protects babies from delayed diagnosis while helping families manage typical teething challenges calmly using safe remedies focused on gum relief rather than unnecessary treatments aimed at reducing non-existent fevers caused by teeth coming through gums alone.
