The web shows endless examples of tooth crown preparation onto teeth with 100% of tooth still far above gum-line. My tooth in contrast is half lost, down to the gum-line. The other half is intact. How to attach a crown on the side where nothing can be prepped? Do they simply cement it directly onto the broken half with minimal preparation? They can still prep and shape the unbroken half of the tooth. Is such irregular shaped crowns normal? Is there greater risk of decay under the crown?

Root canal teeth can crack or break. That is why we recommend a crown over the treated tooth to prevent problems. However, there can still be problems like further breaking and root fractures,etc. If you remove a tooth and want to replace it, the options can be expensive...
The answer is yes, just remember filling and crowns won't change colors onlly natural teeth and tooth whitening is not permanent and must be done at least every 6-12 months good luck

So long as the tooth under the crown is fine and your not bothered by the cosmetics you could leave as is...You can always repair however the repairs usually don't hold to long and may be a waste of money... If you have had the crown for many years I think perhaps just having a new one made...
