I had some problems like that, related to lag. I blew up lots of TNT, some of the terrain looked like was still there, but it wasn't. When you clicked any block, that block "updated" and disappeared. Just relogging fixed the issue. Only happened to me twice.
Your problem happens always? Are you using any mods?
We need a little more information. Perhaps a series of screenshots, or video clip. We also need steps to reproduce. Please read http://goo.gl/hVpEd
Can you provide more information? Are you trying to place the block with the left mousebutton or the right mousebutton?
