It was problematic for me because my baby tooth could move. So it was putting stress on the teeth on either side and that was causing me other dental issues.

The orthodontic surgeon who diagnosed and did my dental work did mention that baby teeth often don't have a strong root and so they can become problematic in a adult mouth, but if I'm honest my dental health at the time wasn't great (I had a cavity where a wisdom tooth grew in and put tension on a rear molar and eventually that molar cracked and it turned out that with my wisdom teeth grown in I had a lot of crowding which eventually led to me having all four molars and four wisdom teeth removed.

I also used to suck my thumb as a kid so some of my problems with the baby tooth may have resulted from that pressure as well. My recollection of all my dental work isn't the greatest so I may have missed some of what the dentist said.

TLDR: If you think your kids don't need to see a dentist for a whole decade, you're wrong.
