Precision laser technology for soft tissue procedures with less bleeding, faster healing, and reduced pain
Not all dental lasers are the same. Different wavelengths and delivery systems are optimized for different tissues and clinical applications. Dr. Ahn uses multiple laser systems to provide the most appropriate treatment for each clinical situation.
Diode lasers are the workhorses of soft tissue dentistry. They're highly absorbed by melanin and hemoglobin, making them excellent for gum tissue applications.
The Nd:YAG laser offers deeper tissue penetration while maintaining selective absorption by diseased tissue. This is the laser used in LANAP therapy.
Erbium lasers have a completely different interaction with tissue compared to other dental lasers. They're highly absorbed by water, making them ideal for precise hard and soft tissue ablation with minimal thermal damage.
Beyond surgical applications, lasers can stimulate cellular healing through photobiomodulation (also called low-level laser therapy). Low-power laser light is absorbed by mitochondria, specifically by cytochrome c oxidase, stimulating energy production and promoting healing.
The fundamental principle of laser dentistry is that different wavelengths of light are absorbed by different chromophores (light-absorbing molecules) in tissue. Melanin (dark pigment) absorbs shorter wavelengths. Hemoglobin (red blood protein) absorbs multiple wavelengths effectively. Water absorbs longer wavelengths. By selecting the appropriate wavelength, we can selectively target specific tissue components.
This principle allows us to remove diseased tissue while sparing adjacent healthy tissue. When the laser wavelength is absorbed preferentially by diseased tissue (which contains more melanin and hemoglobin due to inflammation), the thermal energy ablates that tissue while passing through healthy tissue. This selective targeting is impossible with traditional scalpel surgery.
The exposure time and power settings are crucial. Thermal relaxation time is the time it takes for heat to dissipate from targeted tissue into surrounding areas. By delivering energy in short pulses or using low power settings, heat dissipates before damaging surrounding healthy tissue. This is why modern pulse-controlled lasers provide superior results to older continuous-wave systems.
Laser heat causes blood vessel sealing and collagen coagulation, achieving excellent hemostasis (blood clotting). This happens through protein denaturation at temperatures of 60-70°C. The result is a bloodless surgical field, improved visibility, and faster healing.
Laser light has direct antimicrobial effects. The thermal energy and photochemical effects destroy bacterial cell membranes and DNA. This is particularly valuable in periodontal therapy where eliminating bacteria is a critical goal. Unlike antibiotics that may have reduced effectiveness against biofilm bacteria, laser treatment mechanically eliminates the bacterial cells.

Schedule Your Laser Treatment ConsultationTraditional scalpel surgery cuts through all tissue in its path indiscriminately. Laser dentistry, through the principle of selective photothermolysis, can differentiate between healthy and diseased tissue based on their different chromophore concentrations. Inflamed gum tissue, which contains higher concentrations of hemoglobin and melanin due to increased blood flow and cellular activity, absorbs laser energy more readily than healthy pink tissue. This means the laser naturally removes more diseased tissue while sparing adjacent healthy structures—a level of selectivity that is impossible to achieve with a blade.
One of the most significant clinical advantages of laser surgery is hemostasis. The laser seals blood vessels as it cuts, resulting in a nearly bloodless surgical field. This dramatically improves the clinician's visibility during the procedure, which in turn improves precision and outcomes. With traditional surgery, continuous bleeding can obscure the treatment area and require frequent suctioning and gauze application.
The LANAP (Laser-Assisted New Attachment Procedure) protocol represents one of the most significant advances in periodontal therapy. Using the Nd:YAG laser at 1064nm, LANAP targets and removes the diseased epithelial lining of periodontal pockets while preserving the underlying connective tissue attachment. The laser energy selectively ablates bacteria and inflamed tissue, then stimulates a stable fibrin clot at the base of the pocket. This clot serves as a biological scaffold that promotes true regeneration of the periodontal attachment apparatus, including new cementum, periodontal ligament, and alveolar bone. LANAP is FDA-cleared and supported by histological evidence demonstrating new attachment formation.
Patients who undergo laser procedures consistently report faster recovery and less post-operative discomfort compared to traditional surgery. Because the laser cauterizes as it works, there is less tissue trauma, reduced inflammatory response, and minimal bleeding after the procedure. Many soft tissue laser procedures do not require sutures, and patients can often return to normal eating and activities within 24 to 48 hours rather than the one- to two-week recovery typical of conventional surgery.
Most laser dental procedures involve significantly less pain than traditional surgery. Many soft tissue laser treatments can be performed with minimal or no local anesthesia. The laser seals nerve endings and blood vessels as it works, which reduces both pain and bleeding during the procedure. Post-operative discomfort is also typically less than with scalpel-based surgery.
LANAP (Laser-Assisted New Attachment Procedure) is an FDA-cleared laser protocol for treating periodontal disease. It uses an Nd:YAG laser operating at 1064nm to selectively remove diseased tissue from periodontal pockets while leaving healthy tissue intact. The laser energy targets the pigmented bacteria and inflamed tissue, then stimulates a blood clot that promotes reattachment of the gum to the tooth root. LANAP can achieve results comparable to traditional periodontal surgery with less discomfort and faster recovery.
Laser dentistry offers several advantages over traditional scalpel surgery including reduced bleeding due to immediate hemostasis, less post-operative swelling and pain, faster healing times, reduced need for sutures in many procedures, and the ability to selectively target diseased tissue while preserving healthy tissue. Traditional surgery may still be preferred for certain complex cases or when large tissue flaps are required.
Yes. Dental lasers have been used safely for decades and are FDA-cleared for a wide range of dental procedures. The key to safety is proper training, appropriate wavelength selection, and correct power settings. Protective eyewear is worn by both the patient and clinical team during all laser procedures to prevent eye exposure to laser light.
Dental lasers can be used for a wide range of procedures including gingival contouring and reshaping, frenectomies, gingivectomy, periodontal pocket treatment via LANAP, bacterial decontamination, soft tissue biopsies, vestibuloplasty for implant preparation, photobiomodulation for accelerated healing, and hemostasis during surgical procedures. Dr. Ahn uses multiple laser wavelengths to select the optimal tool for each clinical situation.
