Oral thrush in babies is due to a yeast infection known as Candida. Candida is naturally prevalent in the mouth and on the skin. However, Candida may cause thrush when it develops out of control. Thrush is often seen in nail creases, diaper regions, and vaginas. Oral thrush might occur since the baby’s immune system is still developing and cannot manage Candida levels.
Another probable cause of oral thrush in babies is the recent use of antibiotic treatment. This is because antibiotics might destroy good microorganisms in your baby’s mouth. These beneficial bacteria generally aid in regulating Candida levels in your baby’s mouth. Candidiasis may arise when there are fewer beneficial bacteria present.
Furthermore, your beneficial bacteria levels may be reduced when you’re nursing and have previously been on antibiotics. This may increase your or your baby’s risk of developing thrush.
