Tongue Ulcers and Fever in Babies: Causes & When to See a Doctor

Babies can get a fever from ulcers on the tongue, as ulcers can be a sign of an infection. When the body is fighting an infection, it may produce a fever to help kill the bacteria or viruses that are causing the illness. In addition to a fever, other signs of an infection in a baby may include irritability, poor appetite, and increased sleepiness. If your baby has an ulcer on the tongue and a fever, it is important to see a doctor to determine the cause of the infection and get appropriate treatment.
