A new review finds that teething can make babies miserable, but it rarely causes fevers above 100.4 degrees Fahrenheit, or any other signs of illness, as reported by HealthDay News.

The analysis, published online Feb. 18 in the journal Pediatrics, found that teething most often just causes babies to be a little crankier, drool more and rub their irritated gums.

And while some infants have a slight rise in their temperature, teething usually does not cause a full-fledged fever — or any other signs of illness, according to the researchers led by Dr. Michele Bolan, of the Federal University of Santa Catarina, in Brazil.

If a baby’s temperature rises to 100.4 degrees F or higher, George said, then it’s a fever — and not just a mild temperature elevation from teething.
