I have a friend with extreme food restrictions, they can mostly only eat animal products (plus white rice and very few other things). They also cannot brush their teeth regularly due to disability - yet their teeth look fantastic!

I remember in Sub-Saharan Africa, they all chewed on this stem (can't remember what it was), and everyone I knew had incredible teeth. Their diet was probably also fairly simple. I wasn't really a fan of the local cuisine.

When I lived in Morocco, however, it was the opposite.

Moroccan food is some of the best in the world, but they have sugar in everything. Their mint tea is something that should come with an insulin injector. They buy these giant bricks of sugar, wrapped in blue paper, and just drop them in the pot.

When many Moroccans smile, it looks like a brown picket fence.

Did I mention that Moroccan food is awesome?

The stick is likely Neem; my father did the same in Pakistan.
