Rashes often appear on babies during teething. While teething itself does not directly cause a rash, the increased drooling often associated with it can lead to skin irritation. Various rashes can also coincidentally appear during this developmental stage, leading to confusion about their origin. Understanding the nature of these rashes helps parents provide appropriate care for their infants.
The Common Teething-Related Rash
The most commonly observed rash during teething is known as drool rash or teething rash. This irritation arises from increased saliva production, a natural part of the teething process. As teeth emerge, babies drool more, and this excess moisture accumulates on their delicate skin.
Constant wetness from saliva and bits of food irritates the skin around the mouth, chin, neck, and sometimes the chest. The rash appears as small patches of raised, red bumps, and the affected skin may look chapped or dry. This rash is a secondary effect of prolonged exposure to moisture and digestive enzymes in saliva, not a direct symptom of tooth eruption.
Other Rashes That May Coincide with Teething
Babies can develop various rashes at any time, and the teething phase is no different. Other rashes may appear concurrently with teething but are not directly caused by the process itself. Recognizing these distinctions is helpful for parents.
Heat rash, also known as miliaria, occurs when sweat ducts become blocked. This rash appears as tiny red bumps or blisters, particularly in skin folds or areas covered by clothing, and is more prevalent in warm, humid conditions. Eczema, another common skin condition, can also flare up during teething. Increased drooling can aggravate pre-existing eczema patches, making the skin more itchy and inflamed; the stress of teething might also contribute to these flare-ups.
Viral rashes are common in infants and can occur alongside teething. These rashes, like roseola, often accompany symptoms such as fever, a runny nose, or a cough, and typically resolve on their own. As new foods are often introduced around the same age as teething begins, food rashes can emerge. These reactions can manifest as hives, general skin redness, or a worsening of eczema, appearing shortly after consumption of an offending food.
Caring for Rashes and When to Consult a Doctor
Managing common baby rashes, particularly drool rash, involves keeping the affected area clean and dry. Gently wipe away excess saliva from your baby’s face, chin, and neck using a soft cloth, patting rather than rubbing to avoid further irritation. Applying a thin layer of a barrier cream, such as petroleum jelly or Aquaphor, protects the skin from moisture and aids healing. Using absorbent bibs and changing wet clothing frequently also helps keep the skin dry.
While many rashes are treatable at home, certain signs indicate the need for a medical consultation. Contact a healthcare provider if the rash spreads rapidly, develops blisters or open sores, or shows signs of infection like pus, increased redness, or warmth. A doctor’s visit is also warranted if the rash is accompanied by a high fever, unusual irritability, lethargy, or does not improve within a few days of home treatment.
