What causes milky white secretions on the oral mucosa?

White, milk-like secretions on the oral mucosa may arise from various causes. One possible cause is oral ulcers, a common oral condition that can damage the oral mucosa and lead to such secretions. Oral candidiasis is another frequent cause, particularly among immunocompromised individuals and infants, which may result in thrush—characterized by curd-like white patches that, when shed, leave behind white, viscous, thread-like residues. Additionally, factors such as oral inflammation and periodontitis may disrupt normal salivary gland secretion, resulting in milky discharge. When encountering this condition, it is advisable to maintain good oral hygiene and seek timely medical evaluation for accurate diagnosis and appropriate treatment.
