Sadly can confirm as I had no cavities in high school, did terrible in my 20's especially around 20-27 went through a lot of depression, lack of money/medical care/ in and out of work a lot and I'm trying to fix what I can just starting my 30's after losing 2 teeth It can be hard to overcome shame when already depressed so it's hard to visit a dentist moreso if you have no money to do anything.
It's easy to screw up even more so if you have bad genes on top of it, a lot of my family has issues with teeth.
At least stem cells can be found within your teeth and there is a process now to regrow some of your teeth with your own stem cells, doesn't replace implants though but helps. This process isn't popular yet but at least it's possible in a few areas in the states.
