Fever During Teething – What’s Normal and When to Worry
Many parents notice their baby develops a mild fever or elevated temperature while teething. The big question: is fever during teething normal, or should you be concerned? In short, a slight temperature is common, but a true fever (over 100.4°F/38°C) is rarely caused by teething alone. If your baby’s fever is high, it’s best to check with your pediatrician.
It’s important to know that teething itself rarely causes a real fever. Babies’ immune systems are more sensitive during this stage, making them more likely to catch infections that can cause fever. So, teething and fever often happen together, but they’re not always directly linked.
What Happens During Teething? 🦷
Teething is the process of baby teeth breaking through the gums, usually between 6 and 24 months of age. The gums may swell and become tender, and your baby might be fussier than usual. Common teething symptoms include:
- Increased drooling
- Desire to chew on things
- Mild gum redness
- Restlessness or trouble sleeping
The body responds with mild inflammation, which can lead to a slight temperature—typically between 99.5–100.4°F (37.5–38°C)—that usually goes away in a few days.
Fever or Just a Mild Temperature? Understanding the Difference
A mild temperature (99.5–100.4°F/37.5–38°C) can occur with teething, but a fever above 100.4°F (38°C) is a warning sign. Higher temperatures are more likely due to infection than teething itself.
Practical Example:
- If your baby shows teething symptoms and has a temperature of 100°F (37.8°C) but seems otherwise well, keep monitoring.
- If the fever is above 100.4°F (38°C) and your baby is lethargic, has poor appetite, rash, or diarrhea, contact your doctor.
Why Can Fever Happen During Teething?
Teething causes mild gum inflammation, which can affect body temperature regulation. The immune system is more active, making babies more susceptible to viruses and bacteria. Teething doesn’t directly cause fever, but the stress and inflammation can make your baby more sensitive.

What Symptoms Should You Watch for During Teething?
Alongside typical teething signs, pay attention to:
- Persistent or high fever (over 100.4°F/38°C)
- Poor appetite, lethargy
- Rash, vomiting, diarrhea
- Difficulty breathing, seizures
These are not normal teething symptoms and may signal infection or another illness.
When Should You Call the Doctor? 🚑
Contact your pediatrician if:
- Fever over 100.4°F (38°C) lasts more than 24 hours
- Fever is accompanied by serious symptoms (rash, vomiting, diarrhea, seizures)
- Your baby is very drowsy or unresponsive
- Trouble breathing, constant crying, or extreme fussiness
Your doctor can rule out infections and provide reassurance about your baby’s symptoms.
What Can You Do at Home for Teething Fever?
- Check your baby’s temperature regularly
- Offer plenty of fluids
- Soothe gums with a chilled teething ring or spoon
- Watch your baby’s overall behavior and comfort
- Don’t give fever medicine unless advised by your doctor
Patience and careful observation are key during teething. If you’re unsure, it’s always okay to ask your pediatrician.
Possible Risks
Teething itself isn’t dangerous, but babies are more vulnerable to infections during this time. Persistent or high fever should always be checked by a doctor, as it could signal a more serious illness.
Medical Background
Inflammation in the gums during teething can temporarily affect body temperature regulation, causing mild elevation. True fever (over 100.4°F/38°C) is more likely a sign of infection. Babies’ immune systems are still developing, making them more sensitive to their environment.
Everyday Tips for Parents
- Pay attention to your baby’s behavior, not just the thermometer
- Keep a thermometer handy and note temperature readings
- Comfort your baby with cuddles and gentle rocking
- Chilled teething rings can help ease gum pain
- If fever is high or persistent, don’t wait—call your pediatrician
