Does Teething Cause Fever in Babies? A Doctor Explains

Teething is a natural process in which your baby's teeth begin to come through the gums. It usually occurs during the first year of life. During this time, your baby may become fussy, drool more, or want to chew on things. On the other hand, a fever occurs when your baby's body temperature rises, often because the body is fighting an infection.
Since both can happen during infancy, parents may wonder what their baby is experiencing. Our expert shares the facts about teething and fever and explains when parents should pay closer attention to their baby's symptoms.
Why Do Parents Often Confuse Teething and Fever?Many parents confuse teething with fever because they often occur at the same stage of a baby's development. Most babies start teething between 6 and 12 months of age, which is also the time when they begin exploring their surroundings and putting objects in their mouths.
As a result, they may develop infections that can cause fever. Over the years, many people have also believed that fever is a normal part of teething. This common belief can make it difficult for parents to know the real cause when their baby feels warm.
What Happens During Teething?Teething happens when your baby's teeth start coming through the gums. As the teeth move upward, your baby's gums may become sore or sensitive for a short time. This pressure on the gums can make your baby uncomfortable for a short time. As the teeth come in, your baby may have sore gums, drool more, or want to chew on things to feel better.
Does Teething Really Cause Fever?Teething may make your baby feel slightly warm, but it does not usually cause a true fever. A true fever means your baby's body temperature is 38°C (100.4°F) or higher. As the teeth move through the gums, mild irritation may cause a slight increase in body temperature.
High fever is usually not caused by teething. If your baby has a temperature above 38°C, it may be due to an infection or another illness rather than teething.
Teething vs Fever: Key Differences Parents Should KnowTeething and fever can sometimes happen around the same time, which can make it difficult to understand what your baby is experiencing. Looking at your baby's overall symptoms, behaviour, and temperature can help you tell the difference.
The table below highlights common signs that may help you determine whether your baby is teething or has a fever or illness:
