No Artifacts

.............. ?????????????????????

The dentist has National Geographic Mag in his waiting room. One of the issues was " London Underground and the Past ". This past was represented by bones and objects dug up during the digging for a new subway line.
The dentist found , no artifacts in the hole left by the tooth extraction. He did find a poorly organized clot ( not good ) in the hole. Some foreign object got in there and prevented clot formation , the good kind.
He reamed out the hole ( called starting at square 1 ) and rinsed the hole. Now ,we wait for the healing ( again ). On the plus side and this surprised me ( i.e. that there could be good signs ) there was no pus below the scab. That means that the infection was primarily a surface phenomenon and not deep. However , he did go deep , cleaning out the hole.

I go back in 5 days to get checked. The mantra is keep crap out of the hole. Eat smooth foods for 3 days. 
Beer seems to be smooth.
We'll see what else qualifies as smooth
