Patient presented with crown done 3 yrs ago by another local dentist. History of crown coming loose and being recemented. 6 months ago dentist placed a ‘few’ pins  and cemented with what looked like composite. Came loose again and patient superglued.

Told pt I suspected either the post was loose again or fractured. Turns out the post was fractured. Told patient saving the tooth was probably hopeless but I’d like to try and remove the post .
Set Waterlase at 2.25 30/30 6mm tip and proceeded to remove composite from around the post. Parelleled laser to post and moved in a circular motion. Got down to about 1 mm of post left in composite and still couldn’t budge the thing. Explained to pt that with the depth we were at we could continue but the root would be too weak to hold another post. Pt decided to ext and 3 unit bridge.

Long story short , I wasn’t successful but found it to be an interesting approach due to the lasers end cutting which I assumed should minimize the chance of lateral perforation.   AND… I didn’t fry the tip doing it
