Can Teething Cause a Fever? Here’s What the Science Says

Teething is a natural developmental stage that often causes discomfort as new teeth emerge. Many parents associate teething with a high fever, raising concerns about their child’s health. Understanding the true relationship between teething and temperature is crucial for appropriate care.

Understanding Teething and Temperature

While teething can cause a slight elevation in a baby’s body temperature, it does not typically lead to a high fever. However, research indicates that a low-grade temperature increase, generally below 100.4°F (38°C) orally or rectally, might be observed due to mild gum inflammation as a tooth emerges. If a baby’s temperature reaches or exceeds 100.4°F (38°C), it is generally not attributed to teething and suggests an underlying issue, such as an infection. Attributing a high fever solely to teething could delay the diagnosis and treatment of a more serious condition.

Identifying Common Teething Signs

Beyond temperature changes, common teething signs include increased drooling, which can lead to a rash around the mouth or chest from the saliva. Babies may also exhibit fussiness, irritability, or increased crying due to discomfort.

Swollen, tender, or red gums are direct indicators of an erupting tooth. Infants often chew or gnaw on objects like their fingers or toys to alleviate gum pressure. Changes in eating patterns, such as a temporary decreased appetite or a preference for chewing on solid foods, are also observed. Sleep disturbances can occur as a result of the discomfort.

Recognizing Signs of Illness

It is important that parents distinguish typical teething symptoms from those signaling a potential illness. A high fever, defined as 100.4°F (38°C) or higher, warrants a call to a healthcare professional, especially if it persists for over 24 hours or is accompanied by other symptoms.

Symptoms like vomiting, diarrhea, a widespread rash (not localized to the face from drooling), coughing, or nasal congestion are not typically associated with teething. Extreme lethargy, inconsolable crying that prevents comfort, or refusal to drink liquids also point to an illness. Consulting a pediatrician is recommended if these symptoms appear, as they may indicate an infection or other health concern needing prompt evaluation.

Soothing Teething Discomfort

When a baby is experiencing discomfort, several methods can help soothe teething discomfort. Gently massaging the baby’s gums with a clean finger can alleviate pressure. Offering cold objects like chilled (not frozen) teething rings, pacifiers, or a cool, wet washcloth can numb gums and reduce soreness. Avoid freezing teething rings, as they can become too hard and damage delicate gums.

For older babies on solids, chilled foods like yogurt or applesauce offer relief. If discomfort is significant, over-the-counter pain relievers such as acetaminophen or ibuprofen for infants can be administered. Always follow dosage instructions on the packaging or from a pediatrician, especially for babies under two, and do not exceed the recommended frequency. Avoid topical numbing gels containing benzocaine for babies younger than two due to potential serious side effects.
