What do you think of me hating to brush my teeth?
Why do you hate brushing your teeth?
It's annoying and I've heard that I can live many years with bad teeth.
It's bad to not brush or take care of your teeth. If you don't practice good oral hygiene then you could wind up having major dental problems in the future. I think you should start brushing your teeth every day.
Whatever, bad teeth are great and I don't give a shit.
Your teeth have to last you your whole life so it is wise to take good care of them.
