After applying FL2 gel or foam, how long should a patient refrain from eating or drinking?

The recommended duration for a patient to refrain from eating or drinking after the application of fluoride gel or foam is indeed 30 minutes. This wait time is crucial for the fluoride to effectively remineralize the enamel and enhance its protective benefits. During this period, the fluoride is absorbed by the tooth structure, providing maximum protection against dental caries.

If a patient eats or drinks too soon after the application, they may wash away the fluoride before it has had the chance to provide its full effect. The 30-minute interval is a standard guideline that ensures optimal uptake of fluoride, helping to support stronger and healthier teeth. Therefore, emphasizing this duration can significantly contribute to better oral health outcomes for patients.
