David,
Just curious as to which product you are using with your trays and where you find it.

The Prosthodontics gave me a bottle of Omni Gel by 3M (.4%) and said I should be able to get it at most drug stores, but the ones I have checked don't seem to have that brand and I am not sure if what they have will work OK with the trays.

While being treated at the CCC, I can just walk over to the Prosthodontics office and buy a bottle, but afterwards it would be nice to have a closer source of supply even if it is a different brand.
