Back in the dark ages when women very rarely got into med school (early 60's, pre civil rights act) I had a momentary pause to consider trying to get into dental school. Trouble was, I just didn't want to. Now, all these years later, I'm pleased I had that insight about not being interested. I would probably have been miserable but would have accumulated more in the bank. No matter.
I had sort of a crowded mouth, teeth wise, and when I was 20 or so, had a tooth or two pulled and some caps fixed on. I've no idea if caps are still used, but my caps were and still are white. They are different looking than the other teeth, but they work, which is the key thing.
I am mildly discomfited by many americans' need for perfect white teeth. I can see orthodontia as a real need for some, of course. Many times when I see photos of people in Britain and the persons' teeth are visible, that reminds me of my childhood, when a lot of people had imperfect teeth. I like the photos.
