Without Shouting At Me, Why Do People Claim Dentistry Is Painless When It Just Simply Isnt?

Short question, but why do people do this, whats to gain out of lying that dentistry is painless?

You absolutely CAN feel whats going on, you DO feel needle pain with your injections, you just DO.

Why are people so determined to try and pretend you dont feel the needless, the vibrations, the awful sounds, and the obvious twinges of pain you get throughout your treatment.
