“The Orabrush® Tongue Cleaner features ultra-soft, micro-pointed bristles that reach deep into the uneven crevices of your tongue to loosen and lift away stinky bacteria.

Scraping your tongue with a spoon should be permitted, just don’t make it bleed etc, which I don’t think will happen, and even if the spoon will dislodge some skin cells from your tongue the poskim say that they are not noticeable and you don’t have to worry about it. Regarding using a brush with bristles, it would have the same halachos as using a toothbrush on Shabbos.
