Is drinking 5-6 cups of coffee a day with no sugar bad for your teeth?

Hello, I drink 5-6 cups of coffee a day without any sugar and I am wondering is this bad for your teeth

With or without milk? With milk it's a marginal issue, but not a huge deal, without milk then not a problem at all.

I add milk into it, I just started thinking that what if I am damaging my teeth with the coffee

Theoretically the plaque bacteria can metabolise the lactose in the milk, but in practical terms the effect on your teeth is pretty minimal.

Might not be doing your general health a whole lot of good though, that's quite a lot of caffeine. (Says me who used to get through a fair bit of coffee when I was working!).
