Tooth removal vs removing a tooth / molars removal vs removing of molars [duplicate]

I have a dentistry student who writes things like: "the need for molars removal" and "molar removal treatment" which sounds off to me. I prefer to say (write) "the need to remove molars" and "treatment involving removal of molars", which sound more 'direct' to me.

Yet, I am struggling to explain why my version is more direct.

I'd be most obliged for any pointers...

Thank you!

Solution 1:

You are right. "the need for molar removal" sounds wrong, especially as 'molar's a different specialist meaning chemistry and chemical engineering. "The need to remove a molar" or "extract a molar" is concise and precise
