Can teething cause a high fever?

Teething can sometimes come with mild temperature changes, but a true high fever is not usually caused by teething. Many pediatric sources consider temperatures above 100.4°F to be a real fever, and a fever higher than 101°F is less likely to be explained by teething alone. If your baby has a high fever in teething season, it is important to also consider common illnesses such as viral infections, ear infections, or other causes.

How to tell teething fever vs illness

More likely teething

Drooling, gum rubbing, chewing on objects, mild fussiness, and disrupted sleep can happen with teething. These symptoms may occur without a true fever or only with a very slight temperature rise.

More likely illness

A fever above 101°F, low energy, poor feeding, vomiting, diarrhea, cough, congestion, rash, or unusual sleepiness suggest something more than teething may be going on.

When symptoms overlap

Babies can be teething and sick at the same time. That is why the full picture matters: temperature, behavior, hydration, breathing, and how long the fever has lasted.

When to worry about fever during teething

Fever higher than expected

If the temperature is above 101°F, many parents ask, 'is high fever from teething or illness?' In most cases, that level of fever should not be assumed to be from teething alone.

Concerning symptoms with fever

Call a clinician sooner if your baby has trouble breathing, signs of dehydration, a seizure, a stiff neck, a new rash, persistent crying, or is hard to wake.

Age matters

Any fever in a baby under 3 months needs prompt medical attention. For older babies, the right next step depends on the temperature, duration, and other symptoms.

Why parents often confuse teething and high fever

Teething often happens during the same months when babies start getting more common childhood infections. Because gum discomfort, fussiness, and sleep changes can happen with both, it is easy to assume the fever is from teething. But if your baby has a fever not caused by teething, spotting the difference early can help you decide whether home care is enough or whether it is time to contact your pediatrician.

Frequently Asked Questions

Can teething cause a fever above 101°F?

Usually no. Teething may be linked with mild temperature increases, but a fever above 101°F is more likely to be related to an illness than teething alone.

How high is too high for teething fever?

If your baby has a true fever, especially above 101°F, it is wise not to assume teething is the cause. Higher temperatures deserve a closer look at other symptoms and may require medical advice.

How can I tell if it is teething fever vs infection?

Teething is more often associated with drooling, gum irritation, and chewing. Infection is more likely when fever is higher, your baby seems unusually sleepy, is feeding poorly, has respiratory symptoms, vomiting, diarrhea, or seems generally unwell.

When should I worry about fever during teething?

Worry more if the fever is above 101°F, lasts more than a day or two, happens in a baby under 3 months, or comes with dehydration, breathing trouble, rash, seizure, or difficulty waking your baby.

Can my baby be teething and sick at the same time?

Yes. Teething does not protect babies from infections, and the timing often overlaps. That is why a high fever in a teething baby should still be evaluated based on the full set of symptoms.
