I like the feeling of pulling at my teeth
Why do you like pulling at your teeth?
It's pretty fun, but it does hurt.
Even though it's fun now, you may end up causing damage to your teeth. Then you'll have to get them repaired.
Well I'm going to break parts of my teeth off then if I just have to get them repaired anyways.
You don't have to get them repaired if you just stop pulling on them. It is the pulling of the teeth that damages them.
