Hello, I'm Fifi and this is the English We Speak.
With me is Rob.
Hello, everyone.
Rob, are you okay?
You look in pain.
I am.
I've just been to the dentist.
Oh.
Oh.
Not my favourite place.

And dentists look at teeth.
Sorry, Fei Fei.
That's one tooth related expression that doesn't need a dentist.
When you cut your teeth, you get your first experience doing something in a particular job.
