Dental Doubt

I hate when people say that something is “like pulling teeth”. First of all, how much hands-on experience does the so-called average person have with tooth-pulling? Maybe it’s really not that hard to pull a tooth. Maybe most dentists are girly-armed weaklings, and tooth-pulling is a lot easier than it’s cracked up to be.
Second of all, how hard can it really be? Doesn’t the new-fangled technology of this supersonic modern age extend into the dental profession? There must be ways to pull teeth that don’t involve leverage, pliers, and elbow grease. What about pneumatics? Magnets? Robots? A computer program?
