Recently, a dental crown came loose.
It filled a gap from a tooth that I lost years ago due to neglect.
Root canal and all.
Back in the day, I would brush less frequently, drink soda, and view dental visits as things to avoid.
The result was that I lost a couple of teeth and had some others that needed much help to save.
Since then, my personal dental care has improved significantly.
And, thank God, I haven't even had a cavity in quite some time.
So, when it became clear that I needed to replace the crown (and went through the process of fitting for a new one,) it brought me back to that time when it seemed like I was in for a rude awakening every time I visited the dentist.
