It seems to happen a lot to people who haven't seen a dentist in years.
My mom had a Root Canal when she as a kid when she hadn't seen a dentist in 5 (?) years. The same happened with the kid of one of my bosses...their family moved from Korea about a year before I took a summer job with them. Their daughter, who was about 12 at this point, hadn't seen a dentist in her life and had ~10 cavities and a Root Canal...which needed fixing or to remove the tooth (I had to translate this from the doctor to my boss to simpler English, which is why I know this).
Never seen that dramatic a turn around though. Most of the time you can get an indication of how good your teeth are based on the reaction of your teeth to scaling.
Though, Root Canals are harder to detect until x-rays are looked at if memory serves because of their nature of going so close to the tooth and existing in non-visible locations.
