Just a long shot but I had a similar thing happen to me with one of my Albino Royals ( feeding attempt ) anyways there were about 5 teeth in my hand and many more ' bloody' holes ... I took photos ( obviously lol ) and forgot all about it .. About a week later my hand was sore / itchy reddish . On closer inspection I noticed about 4 teeth STILL under the skin !!

The wife dug them out with a sterilised needle - applied sudacreme and all sorted !!!
