In which form is fluoride often delivered in professional applications?

Fluoride is frequently delivered in professional applications using gel, foam, or varnish formats. These forms are specifically designed to maximize fluoride retention on the tooth surface, providing enhanced protection against dental caries.

Gels can be applied using trays that hold the fluoride in contact with teeth for a specific duration, improving fluoride uptake. Foam is often easier to apply and can fill in areas where a gel might not make complete contact, while fluoride varnish adheres to the tooth surface and allows for a gradual release of fluoride over time, making it particularly effective for promoting remineralization.

These application methods are favored in clinical settings because of their effectiveness, ease of use, and the ability to control the dosage provided to patients. The specific forms mentioned are developed to optimize the therapeutic benefits of fluoride while minimizing the risk of ingestion or absorption that can occur with other delivery methods.
