Can teething cause fever?

Teething may be linked with a slight rise in temperature for some babies, but it should not cause a true high fever. Many parents notice fussiness, drooling, gum discomfort, and a baby who feels a little warmer than usual. In general, a temperature under 100.4°F may happen around teething, while 100.4°F or higher is more likely to be considered a fever and may have another cause, such as a viral illness. Because teething and common childhood infections often happen at the same age, it’s easy for symptoms to overlap.

How to think about teething fever

Low-grade temperature

A mild temperature increase may happen during teething. Parents often describe this as their baby feeling warm, but not truly sick.

100.4°F or higher

A temperature at or above 100.4°F is generally treated as a fever. If your baby has this level of fever while teething, it may not be from teething alone.

Above 101°F

A higher fever deserves closer attention, especially if your baby seems unusually sleepy, uncomfortable, or has other symptoms like cough, vomiting, or diarrhea.

Common teething fever symptoms parents ask about

Warm cheeks and gum discomfort

Babies who are teething may have red cheeks, swollen gums, more drooling, and a strong urge to chew on objects.

Fussiness with disrupted sleep

Teething often causes irritability, clinginess, and more night waking, which can make a mild temperature feel more concerning.

Symptoms that suggest something else

A true fever with congestion, ear pulling, vomiting, poor feeding, rash, or unusual tiredness may point to illness rather than teething alone.

How long does teething fever last?

If your baby’s temperature seems related to teething, it is usually brief and mild. A temperature that lasts more than a day or two, keeps rising, or returns after improving is less likely to be explained by teething alone. Duration matters, but so do your baby’s age, behavior, feeding, and other symptoms. Personalized guidance can help you sort out what’s most likely going on.

When parents usually seek extra guidance

Your baby is under 3 months

Any fever in a very young baby should be taken seriously, even if teething seems to be happening at the same time.

The fever seems too high for teething

If you’re wondering how high is teething fever, the key point is that teething should not cause a significant fever.

You’re not sure what’s normal

Many parents want help deciding whether this looks like baby teething with fever or a separate illness that needs medical advice.

Frequently Asked Questions

Is fever normal when teething?

A slight rise in temperature can happen during teething, but a true fever is not usually considered a normal teething symptom. If your baby’s temperature is 100.4°F or higher, it’s worth considering other causes too.

How high is teething fever in babies?

Teething may be associated with a low-grade temperature, but it should not cause a high fever. If your baby has a temperature above 100.4°F, especially above 101°F, it may be more than teething.

How long does teething fever last?

Any temperature related to teething is usually mild and short-lived. If the fever lasts more than 24 to 48 hours, gets higher, or comes with other symptoms, another illness may be involved.

What are teething fever symptoms in a baby?

Parents often notice drooling, swollen gums, chewing, fussiness, and sleep changes during teething. If these happen along with a true fever, especially with cough, vomiting, diarrhea, rash, or poor feeding, teething may not be the only cause.

Can a baby have fever during teething in infants and still need medical care?

Yes. A baby can be teething and also have an unrelated infection. Age, temperature level, duration, and other symptoms all matter. Babies under 3 months with fever need prompt medical attention.
