Orthodontists

[JockSporran]

Why aren't they called 'orthodentists'? (I'm serious).

[Ethel]

Good question.

An orthodontist practices orthodontics - which is from two latin words:

Ortho - to straighten

Odon - tooth.

So you can see it literally means 'straighten tooth'.

My orthodentist is a bender.

[JockSporran]

Ethel - so why aren't dentists called dontists?

[Ethel]

Because we use the word dentist from the French word dentiste, dent = tooth.

[meredith101]

so why are orthodentists prononounced 'orthodontists' and dentist pronounced 'dentist'?
