Applying the Fluoride Treatment
Fluoride treatment may be applied as foam, varnish, or gel. The dentist applies it using a brush, swab, tray, or as a rinse. The application process is quick, and the fluoride is left on the teeth to absorb. You should avoid eating or drinking for 30 minutes after the treatment for optimal effectiveness. After this period, you can resume your regular oral care routine, including brushing and flossing.
