Mariah the person who wrote that post, did so in 2005. I think a few of the posts back then were less positive about how easy it is to get and wear braces.
Luckily we're able to relate that pain is rare ... and since I've not had any related to having braces, I'm more than happy about that!
I've had a few cavities ... again no pain ... mostly as a child of the 70's. I never knew I had them until my school dental checkups and they were filled without pain and from memory the only annoying part was not being able to chew on that side (where the filling was) for a few hours. As an adult I've not had any fillings, but have had to have fillings replaced ... and again ... pain free!
