If you don't have plumber's putty, you can also use silicone sealant
(caulk). In fact, some manufacturers actually recommend silicone now as it
doesn't discolor porcelain the way that some plumber's putty will.

What will the consequences be if I don't use plumber's putty around
the drain before inserting it into the sink hole?

Can you overtighten a fiber glass sink drain?
