Crown fell off... does this photo look bad?

[mrkat]

I got a root canal done around 5 years ago and a crown put on top. The crown fell out yesterday and now looks like this:

Is this normal?? Is that decay and what is with the red parts??

I will be going to a dentist but just wanted some general advice as I may travel abroad, depending on what I need to get done (eg if an impant would be better than replacing the crown), to get the work done cheaper and at a better standard.

Thanks
