Hi Andrew,

Many of us, including myself, have been told to use them daily for life for at least 5 minutes though there are some variations for others. I do mine for 7-10 minutes each night before I go to bed.

There are a few other threads on the forums on this topic, so you could search 'flouride' to see previous activity.

Regards,
Nancy
