However what about brushing your teeth? Most people would brush their

Use caustic soda for excellent results.

Some toothpaste (e.g. Maclean's Whitening, which I have some of
in the cupboard) does contain caustic soda.

I think those have got sodium bicarbonate; caustic soda is sodium
hydroxide, which is altogether different. Caustic soda would be a very
effective tooth-cleaning agent; the problem is that it would also be a
rather effective flesh-dissolving agent as well.
