Hi all,
I would like to add that Eileen is right about nothing to drink for 30 minutes after application and you should add to that nothing to eat as well.
Also, for anyone who is or wants to bleach their teeth to whiten them, whitening products will not work after fluoride application. So, use your whitening products before you use your fluoride.
The best time of day to use fluoride, of any type, is before bedtime. Eileen also mentions this in her post for the sake of conveinience but, she as well has picked the perfect time. When we sleep our saliva production goes down considerably. Once again, for those who have a less than normal saliva function, less saliva means less natural defense against bacteria that cause cavities and gum disease. Applying fluoride before going to bed accomplishes two goals in protecting your teeth and strenghtehning them and killing bacteria when your natural defenses are lower. Fluoride is, in fact, a substance that kills bacteria.
Cheers,
Mike
