Thrush is generally due to an imbalance in the microbial flora, leading to an infection by Candida albicans. It is common in newborns and infants. Children who have long-term malnutrition, diarrhea, or who have been treated with broad-spectrum antibiotics or corticosteroid hormones may also be susceptible to thrush. Additionally, if the mother has an infection with Candida albicans in the intestines, or if there is contamination on the nipple during breastfeeding, or if the nursing equipment is infected with fungi, this could also lead to the occurrence of thrush.

Is thrush prone to recurrence?

Oral thrush is due to an infection with Candida albicans in the mouth, and it is relatively easy to recur. It primarily occurs in children who have been frequently ill recently and have taken a lot of antibiotics, or in those children who have low immunity. Under these conditions, if oral care is poor and these adverse factors persist, then the child's oral thrush is particularly prone to recurrence. Therefore, once oral thrush is diagnosed, it is essential to treat it actively. After treatment, it is necessary to treat the area with sodium bicarbonate for a period of time. If antibiotics or corticosteroid drugs are still being used, preventive treatment should also be carried out to completely cure the oral thrush. (Please use medication under the guidance of a doctor)

Does thrush hurt?

Thrush is caused by an infection of Candida albicans, forming white plaques on the surface of oral mucosa. Typically, it presents as small dots or patches on the oral mucous membranes that resemble curdled milk and can gradually merge into larger patches. They are not easily wiped off, without surrounding inflammatory response. Forceful removal might result in local mucosal redness, roughness, and possible bleeding. Generally, it is painless, does not cause drooling, and does not affect feeding. In severe cases of thrush, the white mucosal coating can extend to the pharynx, esophagus, trachea, and lungs, leading to symptoms like refusal to eat, low-grade fever, difficulty in breathing, and even life-threatening conditions. Typical thrush does not involve significant pain.

Can thrush heal by itself?

Thrush is generally caused by a fungal infection due to an imbalance in the microbial flora, primarily involving the formation of a white plaque membrane by Candida albicans on the surface of the oral mucosa. It is mainly seen in individuals with lowered immunity, such as those with long-term malnutrition, repeated use of antibiotics, diarrhea, or the use of certain medications like corticosteroids. Additionally, unsanitary conditions during breastfeeding, fungal contamination on the mother's nipples, or fungal infection from nursing equipment can also lead to thrush. Typically, thrush does not require special antimicrobial medication. If the baby's immunity improves and their intestinal flora are properly established, thrush can heal spontaneously. It is generally recommended to orally take some probiotics and enhance oral care, which can include cleaning the oral cavity with 2% sodium bicarbonate before and after breastfeeding, or locally applying antifungal agents to suppress the fungal growth in the mouth.

What does thrush look like?

Children with thrush mainly suffer from an infection by Candida albicans. In the child’s oral mucosa, including the lips and pharynx, a white membranous substance can be observed, which cannot be wiped off. In this situation, thrush should be considered. Often, it is due to the child repeatedly having an infection, the long-term use of antibiotics or corticosteroids, leading to decreased immunity and thus the occurrence of thrush. Therefore, it is essential to pay attention to oral care. Once thrush is diagnosed, the child should be locally treated with a sodium bicarbonate solution and an antifungal to quickly treat the thrush. At the same time, it's important to prevent diseases from entering through the mouth. All items entering the mouth, like bottles and milk utensils, should be sterilized at high temperatures.

Does thrush need treatment?

Oral thrush is a white Candida infection of the oral mucosa, which certainly requires timely treatment. Firstly, oral thrush causes discomfort in the mouth; secondly, if left untreated for an extended period, it may also spread to the pharyngeal area. Thirdly, recurrent episodes of oral thrush can lead to decreased immunity and may facilitate subsequent infections. Therefore, active treatment is necessary. Treatment primarily involves using 2% baking soda solution to rinse the mouth. In severe cases, adding nystatin for oral rinsing might be required. Of course, maintaining good oral hygiene is crucial, and all tools that come into contact with the mouth must be thoroughly disinfected.
