This article compares and contrasts the differences in hemostasis and coagulation of erbium, carbon dioxide, and diode (hot-tip) dental lasers.
Overview of Dental Diode, Erbium, and Carbon Dioxide Lasers in Soft-Tissue Laser Surgery
Dental Diode Lasers (Hot-Tip Devices)
Unlike carbon dioxide and erbium lasers, soft-tissue ablative dental diodes are contact thermomechanical cutting devices. Their coagulation depth depends on the degree of the diode’s glass tip charring and can range from sub-millimeter (heat propagation-driven coagulation for significantly charred tips) to multi-millimeter (photothermal radiant coagulation for poorly charred tips). “… The diode laser is basically a slow large electrosurgery …” – Gordon Christensen, DDS.
Erbium Dental Lasers
Erbium laser wavelengths circa 3,000 nm are highly energy efficient and spatially accurate for photothermal ablation; their photothermal coagulation depths are significantly shorter than gingival blood vessel diameters. This makes erbium lasers great at cutting soft-tissue but poor at coagulating.
Carbon Dioxide (CO2) Dental Lasers
CO2 laser wavelengths circa 10,000 nm are extremely effective and spatially accurate photothermal ablation tools with exemplary coagulation ability as a result of a close match between their photothermal coagulation depths and the diameters of oral soft-tissue blood capillaries. In nonablative applications, coagulation depth can be increased for long pulses with extended heat propagation-driven coagulation depth in excess of the photothermal coagulation depth.
The key to successful applications of soft tissue CO2 lasers and their advantages over other dental laser wavelengths is their ability to accurately cut and efficiently coagulate the soft tissue at the same time.

Cost of Disposable Tips for Dental Diodes
The initial cost of a diode laser system is fairly inexpensive, however most all diode lasers require single-use disposable tips. The average cost of a single diode laser tip is around $6. This added expense can really add up over time and cost thousands of dollars per year. LightScalpel CO2 lasers offer tipless autoclavable handpieces.

The American Laser Study Club (ALSC), offers several laser dentistry continuing education courses across the United States. The ALSC’s curriculum overcomes the known limitations of many laser dentistry courses and includes the detailed physics of soft tissue ablation and coagulation with laser and hot tip (non-laser) devices. See the ALSC’s upcoming laser dentistry courses.
Comparing the LightScalpel CO2 Laser to Dental Diodes
The LightScalpel is the finest instrument I have used for performing tongue and lip-tie surgeries as well as many other procedures. I use it at least four times a day. Before, we were using a diode laser and it doesn’t even compare. Before, a frenectomy would take around a minute or more. Now with the LightScalpel, it’s about 20 seconds. The moms report less pain for their babies (they eat better and are less fussy)…

CO2 is the gold standard for laser technology, for soft tissue procedures… [diodes] are inefficient compared to the speed of CO2… CO2 simply cuts and ablates tissue much faster.
