Broken tooth on chain ring

This year's Major Taylor Century had terrible cold, wet weather. I ended up bailing with Gary at the first rest stop. We ended up with 52 miles. When I got home, my bike was a total mess and was covered with dirt, grime and junk. Around mile 25, my crank started to squeeek very loudly. When I got home, I did a quick wash/rise with simple green foaming cleaner, but it was still squeeking.

Last weekend, I decided to give it a complete wash and clean out the bottom bracket. It was rather dirty. When I took off the crank and chain rings, I noticed the wear. A few of the teeth were dented and bent and 1 tooth actually broke the tip.

On the last photo, the tip broke off the tooth on the far left. I have no clue when it broke, but it's definitely got wear. Since my chain ring is badly beaten, I'm thinking of replacing it with either a mid compact or rotor Q ring. I haven't decided.
