About cavities...

There is now controversy about the way cavities are diagnosed.

Usually, the dentist sticks a poker into the enamel, and if it feels a little soft, he calls it a cavity and proceeds to drill out an enormous amount of perfectly good enamel and fills it.

I am very skeptical about this method of diagnosing cavities.

I also have heard more and more news stories about dentists (even long-term friend-of-the-family dentists) telling people they need cavities when they don't. I heard a report that up to 50% of people who got a second opinion from another dentist found out that they did not need fillings at all.

I personally know people who have been going to the same dentist for years and when they heard about this, began getting second opinions and found out that their dentist was diagnosing cavities that didn't exist.

Unfortunately, even the seemingly-nicest people have a dark side, especially when they don't think there is any chance of being found out.

I always say, you know the true character of a person by what they do when nobody is looking.
