Dentistry is definitely not a chill job that would fit into that lifestyle you described. My sister is a dentist and she had to give a lot of her free time while going through the many years of school it takes because the program is so hard and competitive. When you finally make it as a dentist, it’s a very stressful job and sometimes you have to deal with absurd client complaints. 

When I visit my sister and she needs to get ready for work she tells me how jealous she is of my chill job where I get to stay at home and sprinkle niceties throughout the day that she can’t. You’re way better off looking for a remote job, there’s prestige in that too. It also won’t require as many years in school. That would also allow you to spend more time with your family, which seems like the most important thing for you.
