I tried drinking coffee through a straw one summer because it’s supposed to protect your teeth.

I’m pretty sure I’m at a greater risk of throat cancer now, and other than that I’m not too sure why you would want them.

If that's a concern, the more practical solutions are to 1) brush your teeth after drinking coffee or 2) don't drink coffee.

I do choose to drink coffee and don't brush immediately after and accept the risk to my teeth.

I was worried about the effect of soda on my teeth so I stopped drinking it.

Which is why it's not recommended to use a straw with hot beverages, only cold ones.

hot drinks != use straw

cold drinks = use straw

My teeth hurt if I drink icy beverages without a straw. I think it can also contribute to tooth staining, and probably cavities if it's a sugary drink.

There are people with disabilities that make it difficult to impossible for them to drink without using a straw. Until plastic straws were banned, they were transparently accommodated by the existing systems.

Now, they're shamed for or outright prevented from using the accessibility devices that allow them to actually, y'know, consume necessary and lifegiving liquid.

Straws were originally introduced for public health reasons, so that your mouth need not touch a surface previously touched by someone else's mouth (and which was not well-cleaned).

I'm not aware of any studies confirming or denying their advantage in the era of modern food safety standards.
