Brushing your teeth or wiping your bum – you have to give one up. Which one would it be and why?

Now here is the thing. Wiping my bum would be a great choice cause you didn't specify washing my bum. Though if you wanted a more satisfying answer, the feces or any excrement from my bum would dry out and probably flake. Now brushing my teeth would have a more dire consequences as it can lead to painful teeth issues as for a long term pain as well as probably being able to see the amount of build up plaque. Also eating is MOSTLY our daily everyday routine compared to wiping a bum
