There are 2 types of teeth, primary and secondary. Primary teeth are often referred to as baby teeth. These are the ones that are expected to fall out eventually. Secondary teeth are your (hopefully) permanent teeth. There are 20 primary teeth and 32 secondary. Primary teeth are notated with letters, secondary teeth with numbers.
Also, all of your teeth (except for your MIGHTY INCISORS) have six sides to them.

Because a young patient who was seen in my office had a two surface filling done on one of their teeth. It was a primary tooth, tooth "J", and the surfaces in question were the lingual and the occlusal. The procedures office fee was $153, but the insurance would only pay $93 of it. But all I could see was "J-LO, $153, $93".
So now we know how much her love DOES cost, no matter how much she protests to the contrary.
