White Tongue in Babies: Milky Whiteness or Thrush?
Dear mothers, white spots on babies' tongues often cause concern. Especially milky whiteness and thrush are often confused because they are very similar to each other. However, there are important differences between these two situations.
What is Milky Whiteness?
In breastfed babies, a white layer may form on the tongue after breastfeeding. This is usually caused by milk residue and is completely normal.
Milky whiteness is harmless and often does not require any treatment.
How Do You Understand Milk Whiteness?
When the white layer is gently wiped with the help of a clean cheesecloth or a mouth swab used as recommended by a doctor, it is easily cleaned and healthy, normal oral tissue is visible underneath.
Therefore, milky whiteness is generally an innocent condition and does not negatively affect the baby's health.
What is Thrush?
Thrush is a fungal infection that occurs in the mouth. It can be seen especially in newborns and young babies.
The most obvious symptom of thrush;
- On the tongue,
- Inside the lips,
- On the inner surfaces of the cheeks,
- In some cases, in the throat area,
These are white or cream colored plaques that appear.
What is the Difference Between Thrush and Milky Whiteness?
The white plaques seen in thrush are not easily removed like milk residues.
When you try to scrape it lightly, the underlying tissue may appear red or bleed slightly. This is one of the most important distinguishing features of thrush.
How Does Thrush Affect the Baby?
Thrush does not only cause whiteness in the mouth. It can also make it difficult for the baby to feed.
In babies with thrush:
- Uneasiness during sucking,
- Don't let go of the breast frequently,
- Refuse to suck,
- Crying during feeding,
may occur.
Swallowing a fungal infection in the mouth may also cause increased gas and digestive problems in some babies.
It Can Also Be Seen on the Mother's Breast
Thrush can be seen not only in the baby but also in the breastfeeding mother.
On the mother's nipple:
- Itching,
- Sensitivity,
- Cracks,
- Burning sensation,
- Whitening,
may occur. Therefore, it is important to evaluate the mother and baby together.
What Can Be Done at Home?
If thrush is suspected, a healthcare professional should be consulted first.
One of the supportive methods that can be applied at home, in line with the doctor's recommendation, is to gently clean the inside of the baby's mouth and the mother's nipple with the help of a clean cheesecloth, using a solution prepared with carbonated water.
However, these practices do not replace treatment and must be supported by expert opinion.
Is Thrush Caused by Breast Milk?
A common misconception among mothers is that thrush is caused by breast milk.
However, thrush is usually not caused by breast milk;
- Failure to provide adequate breast care,
- Failure to clean pacifiers and feeding bottles with sufficient hygiene,
- Due to inadequate oral hygiene,
can be welded.
Therefore, it is of great importance to pay attention to hygiene rules and clean pacifiers and bottles regularly during breastfeeding.
Result
Whiteness on your baby's tongue does not always mean thrush. Milky whiteness, which often occurs after breastfeeding, is completely normal and harmless. However, if the white plaques do not disappear, your baby has difficulty in sucking, or widespread white areas appear in the mouth, the possibility of thrush should be evaluated. In such cases, the best approach would be to consult a healthcare professional without wasting time.
