Infant fever teething: what’s going on and what you can do

Your baby is teething… and suddenly, their temperature climbs. Maybe the thermometer shows 102°F or even 104°F. You wonder, “Is this from teething? Or is something else going on?” You’re not the only one asking. Infant fever teething is common, but it can also be confusing.

In this article, we’ll explain what to expect, what you can do, and when to check in with your pediatrician or nurse.

Teething and fever: what’s normal?

Most babies start teething between 4 and 7 months. And yes, it can come with discomfort. Infant teething and fever sometimes go hand in hand. But usually, the fever is low-grade, around 100.4 to 101.3°F. Still, many parents report higher numbers. Their infant has a fever from teething as high as 102°F or 103°F. So the doubt sets in: is this still normal?

Infant teething fever: what’s really happening?

When teeth push through the gums, it causes minor inflammation. This can trigger a mild immune response, leading to fever. Common signs of teething and fever in infants include:

Fussiness and crying
Poor sleep
Lower appetite
Drooling
Flushed cheeks
Putting hands or anything in the mouth

If these symptoms come with a mild fever, chances are your infant teething fever is totally normal.

Can an infant have a fever from teething?

Yes, it happens. Some babies spike a higher temperature when teething. Seeing a 102°F fever from teething in infants isn’t unusual, especially alongside other teething signs like chewing, drooling, and irritability. Still, it’s good to stay alert.

You should call your doctor if:

The fever lasts more than 3 days
Your baby seems unusually drowsy or distressed
The temperature hits 104°F or higher

Because even though infant fever teething is common, it can also be a virus or infection. Trust your instincts.

What to do when your infant has a fever while teething

If your baby is content and their fever stays under 101.3°F, you likely don’t need to do anything. But if they’re clearly uncomfortable, try:

Extra fluids to avoid dehydration
Dressing lightly and keeping the room cool
Lots of cuddles and comfort
Infant acetaminophen, but only after checking with your pediatrician

When will my infant start teething and show these symptoms? Every baby is different, but your calm presence can make a big difference.

Can teething cause fever in infants?

Yes, but only mild. Infant fever teething usually stays within a safe range. If the fever gets too high or lasts too long, call a doctor. You know your baby best. And even if the fever from teething in infants is usually harmless, it’s always okay to ask for help.
