White patch on gums of toddler. Else?

It's important to consult a pediatric dentist or a healthcare professional who can examine your son's condition in person and provide an accurate diagnosis. They will be able to recommend appropriate treatment options based on his specific needs. The white patch with a red surrounding on your son's upper gum area could have several potential causes. It could be a canker sore, which is a small, painful ulcer that can develop inside the mouth. Canker sores are usually round or oval with a white or yellowish center and a red border. However, it's also possible that the white patch could be due to oral thrush, which is a fungal infection caused by Candida yeast. Oral thrush often appears as creamy white patches on the tongue or inside the cheeks. Given your son's history of dental decay and abscesses, it's essential to seek professional dental care. A dentist can evaluate the extent of the decay and assess the condition of the affected teeth. Treatment options may include dental fillings, extractions, or other appropriate interventions to address the abscesses and decay. It's not advisable to apply ointments or give antibiotics without professional guidance. The appropriate treatment will depend on the underlying cause of the white patch and the overall condition of your son's oral health. A healthcare professional will be able to recommend the most suitable course of action, which may include topical or systemic medications, depending on the diagnosis. I highly recommend reaching out to a pediatric dentist or healthcare professional as soon as possible to have your son evaluated and receive appropriate treatment. They will be able to provide the specific guidance and care needed to address your son's dental issues and alleviate his discomfort.
