Colgate Gel-Kam uses Stannous Fluoride (0.4%) which stains the teeth.

There are other products that use Sodium Fluoride (1.1%) that don't stain the teeth.

I started with a Stannous Fluoride product, but due to heavy staining was switched to one based on Sodium Fluoride.

I was told that either product is fine. Currently I use Neutra Maxx 5000 Gel, but there are a number of other brands available.

You might want to discuss this with you Cancer Center's Dental Group or OC Dental professional.
