How may high-risk patients use fluoride gels at home?

Using fluoride gels with a custom tray at bedtime is an effective method for high-risk patients to deliver concentrated fluoride to their teeth. This approach allows for better retention of the fluoride in the mouth, maximizing its anti-cavity benefits. The custom tray is designed to fit the individual's dental arch, ensuring an adequate and consistent application of fluoride gel over the surfaces of the teeth. This method is particularly beneficial because it promotes prolonged exposure to fluoride, which can help in the remineralization of enamel and provide protection against dental caries, especially for those considered at higher risk due to factors such as previous cavities, xerostomia, or orthodontic appliances.

Other options, such as swallowing the gel or mixing it with mouthwash, do not promote effective fluoride application. Brushing with fluoride gel during the day could potentially lead to inadequate fluoride retention and less effective treatment compared to using a custom tray at night.
