A fluoride rinse is a liquid solution that contains fluoride, a mineral known for its ability to strengthen tooth enamel and prevent cavities. It is often used as a preventive measure in dental care, especially for individuals at higher risk of tooth decay. The rinse is typically swished around in the mouth for a specified time before being spat out, allowing the fluoride to coat the teeth. Using a fluoride rinse can be beneficial for both children and adults. It is commonly recommended by dentists as part of a comprehensive oral hygiene routine, which includes regular brushing and flossing. Regular use can help maintain dental health and reduce the likelihood of cavities.
