Working at

Light Speed
Using a laser to remove amalgam and prepare teeth
saves time and provides a better patient experience
by Dr. Joshua P. Weintraub
Joshua P. Weintraub, DDS,
is a 1996 graduate of the
University of Maryland
Dental School. He began
his dental career in the
U.S. Navy Dental Corps as
a lieutenant in Okinawa,
Japan, followed by the
Navy Yard in Washington,
D.C. He entered private
practice in 1999 and has used dental lasers since
2008, including erbium and Nd:YAG. He currently uses
a CO2 9.3µm laser (Solea, Convergent Dental) in his
practice and is an international lecturer.

Anesthesia-free dental procedures are a
reality. The ability to work without anesthetic
provides benefits for my patients as well as
for my practice-the patients have a better
experience by not receiving injections and
by experiencing a shorter appointment time.
In this case I utilized a 9.3µm CO 2
all-tissue dental laser by Solea while I placed
two Class II restorations anesthesia-free. I was
able to use the laser to assist in the removal
of an old amalgam and prepare an adjacent
iatrogenically damaged, decayed tooth.
The use of the laser reduced the appointment time from what would be approximately
1 hour, 20 minutes with traditional instruments to less than 50 minutes.

Case summary
A 46-year-old patient presented to the
practice for his second appointment. The oral
evaluation had revealed an old and failing

amalgam on tooth #14 MOBL (Fig. 1).
The preoperative radiograph showed that
tooth #13 distal had iatrogenic damage and
decay (Fig. 2).

Treatment plan
The clinical objective was to remove
the amalgam and recurrent decay on
#14 and decay on #13 and restore both
teeth. The treatment was completed
using an all-tissue laser and a highspeed handpiece, all without anesthesia.

Technique
I began the treatment by removing the
failing amalgam restoration on tooth #14. No
anesthetic was required; the laser was used
to trough around the amalgam and outline
the preparation (Fig. 3). The 0.75mm spot
size and a cutting speed between 50% and
60%, with 100% mist, were used to ablate
