Medical Mythbuster: Teething Can Cause Your Baby to Have a Fever…

For seemingly forever, a host of symptoms and behaviors have been attributed to infant teething – including fever. However, it’s important for parents to know that teething does not cause a fever in babies.

This myth is probably rooted in the fact that teething can cause a slight rise in a baby’s temperature. However, this slight rise does not meet the definition of a fever, which is 100.4 degrees F or above. A meta-analysis, published in the journal Pediatrics in 2016, which reviewed many different studies on teething, concluded that gum irritation, irritability and drooling were the main indications of infant teething – but not fever.

So parents shouldn’t automatically attribute a temperature of 100.4 or higher to teething. It more than likely means your baby is fighting an infection and may need to be seen by their healthcare provider.
