Which form of topical fluoride is NOT commonly used?

Topical fluoride treatments are essential in dental care for preventing caries and strengthening enamel. Among the various forms of topical fluoride, the most commonly utilized are gels, varnishes, and foams. Each of these formulations has specific applications and benefits within clinical practice.

While solutions do exist in the realm of fluoride treatments, they are not as commonly used in practice as the other options. Varnishes are particularly popular due to their prolonged retention on the teeth, allowing for better fluoride uptake, while foams and gels are favored for their ease of application and effectiveness.

In professional settings, the choice of fluoride treatment typically prioritizes those forms that provide optimal patient compliance and fluoride retention. Thus, while solutions can be effective, their use is less frequent compared to the more established methods like gels, foams, and varnishes. This is why the solution is identified as the option that is not commonly utilized in dental practices.
