Does drinking coffee through a straw help prevent discolouration of teeth?

okay so basically i want whiter teeth but i love my coffee. So i did some research and seen someone say about using a straw when drinking coffee as it won't touch your teeth. Is this true? my friends find it funny that i use a straw and think its ridiculous cause your not supposed to use a straw with hot drinks but surely if you let it cool down a bit first there's no problem.

I just think it makes sense it wouldn't be in your mouth as much and would go straight down your throat rather than around the mouth.

my mum tried to get me to stop because sucking from a straw can cause wrinkles on the mouth overtime but i mean there is relaxed mouth ways to drink from a straw and not purse your lips so much.

so in conclusion can coffee be drank from a straw to prevent staining teeth?
