Ha!! The old bait and switch! The threats are a famous game of dentists. Let me do this, and possible you won't need that.....BS!! Then they tell you later you are going to need it anyway. I wonder what their cut is for passing people onto gum surgeons? I bet there is some kind of payback.
There is a link on that website to biological dentists by the way for anyone that cares to look.
I'm so thankful you had the presence of mind to say no! Have no fear, OP is not letting you down. You may not feel or see anything, but the good is there, absolutely.
