Had a new patient come in a 2 weeks or so ago after going to the oral surgeon and had a sharp point sticking out on the lingual of the #32 US (#48 international) and it cut the Heck out of his tongue.
WIthout local , using only topical (One touch and also Spray) I used the erbium without water at 30 Hz and 50 mj and then with water slightly to flush out the area and smooth it out.
He was so relieved and I was too to capture the offending piece.
The remaining solid bone was sharp on my finger so I smoothed it off a little with the laser.
He was ecstatic and really liked the fact that I could show him the case with the scope ( which helped me see it) and the laser which helped me remove it.
Neat case and easy without anesthetic needed.
