How come when the Orthodentist say, “we’re going to need to remove a few teeth” it suddenly turns in to EIGHT teeth?

As my son pointed out to me a few is two, three at the most; NOT eight.  He is an astute child but they are his eight teeth.

My BA-BEE!

If anyone wants me, I’ll be wimpering under my desk thinking about the pain of pullin ‘a few’ teeth.
