Your question is pretty much asking if ANYONE can do dentistry...and the answer is no.
Face it...it's a skill, and not anyone can acquire that skill. A vast majority can learn to do it with hard work to a level that is sufficient, a few are naturals, but there is always going to be a large group of people who cannot do the necessary hand skills to become dentists. Most of those who cannot do it are part of the geneal world population that never apply to ental school...i'm sure that the application process may weed out a few who may not ever have what it takes 9as well as many who do) and a few probably make it into dental school and then find out they can't cut a crown.
It's like anything else in life. I have a friend who tried repeatedly to finish high school...no one expects that he would be a great scholar.
I have a friend who trips climbing stairs...no one expects him to be a great dancer or ice skater.
In the same regard, not everyone can do dentistry. Some can't hack the science courses, some can't take the job environment, and, yes, some don't have the hand skills.
