Can povidone-iodine be applied inside the mouth?

Iodophor should not be applied inside the mouth.

Iodophor is a broad-spectrum antiseptic commonly used in daily life for disinfection of the skin and mucous membranes. Although iodophor may have some disinfectant effect on minor inflammation or injuries of the oral mucosa, the oral environment is complex and sensitive. Direct application of iodophor may cause risks such as irritation to the oral mucosa, pain or discomfort, and could potentially disrupt the balance of normal oral flora.

Therefore, in general, it is not recommended to directly apply iodophor inside the mouth unless under the guidance of a doctor or healthcare professional for localized disinfection of specific oral conditions. For routine oral hygiene and care, it is recommended to use specialized oral care products, such as mouthwash or toothpaste, and maintain good oral hygiene habits. If any oral discomfort occurs, seek medical attention promptly and follow the advice of a healthcare professional for treatment.
