Completely rotten, enamel gone, just soft, rotting pulp tissue left. (That part was soft and squishy.) And also probably only 1/3rd of the size it should be... the rest had rotted away.

I've also had three root canals on the 1-7, 4-7 and 3-6.This is what drinking Coca-Cola for 15 years while going through 1-2 year phases of depression and degeneracy, not caring for oneself, not brushing teeth daily or often at all, will do to you.Humans greatest failures are the inability to learn from each other, and the inability to learn quickly from oneself. This is a true addiction and one that affects my life adversely.

I will likely need veneers, implants or dentures within the next 20 years. I say all this full well knowing I could have prevented it, and I could improve my current situation... though I'm sitting here writing this post while drinking a Coke.You only get one body, and even moreso, you only get one set of teeth. Make sure to live your life to the fullest while keeping yourself safe and healthy. There are some things you just don't get second chances with.
