Has anyone heard about a relation between brushing with baking soda/peroxide and mouth cancer? Any refereed journal article on this subject?

Curiosity got me so I googled significantly... and find no mention of a relationship. In fact to the contrary I find use of baking soda and/or peroxide
suggested to cancer patients for various reasons:

HI,
I do know that brushing with hydrogen peroxide can help with gingivitis, as my Dentist recommended it years ago. It did help, along with the work he did to rid it.
Best of luck.
