Reducing Pain, Restoring Function, and Advancing Patient Wellness
Written by: Dar Radfar, DDS
Pain Relief Through Innovation
Dentists often find themselves in the position of managing pain—sometimes causing it during treatment, then working to relieve it afterward. As dentistry continues to evolve, so does our ability to provide care that supports both oral and systemic wellness. One of the most transformative technologies I’ve integrated into daily practice is low-level laser therapy (LLLT), also known as photobiomodulation therapy (PBMT). In partnership with Erchonia, a leader in medical laser innovation, I use LLLT to reduce postoperative pain, accelerate healing, manage temporomandibular joint (TMJ) disorders, and even enhance sleep apnea treatments. I have also personally benefited from this technology to relieve years of neck and back discomfort caused by decades of clinical practice.
A Proven Science, Not a Trend
While LLLT may seem new to some in dentistry, its scientific foundation and clinical success are well established. Chiropractors and physicians have long used light therapy to decrease inflammation and stimulate healing. Veterinary medicine relies on it to help animals recover from injury without drugs or invasive procedures. The mechanism is well understood: when tissues are exposed to specific wavelengths of light, the energy stimulates cellular repair by acting on the mitochondria. The result is improved cellular metabolism, reduced inflammation, and accelerated tissue regeneration. Erchonia lasers, engineered within these precise therapeutic parameters, are FDA cleared for multiple indications. This isn’t “alternative care,” it’s advanced science that’s finally found its rightful place in dental practice.
How It Works
LLLT promotes healing through photobiomodulation, a biological process in which light-sensitive cellular components absorb light energy. One of the primary targets is the mitochondria, the cell’s energy powerhouse. When stimulated by low-level laser light, mitochondrial activity increases, leading to greater ATP production and enhanced cellular metabolism. This process also reduces oxidative stress and downregulates inflammatory pathways, while stimulating collagen synthesis. The result is faster, more complete healing—all without generating heat, causing tissue damage, or introducing pharmacological side effects. In short, light therapy activates the body’s natural healing engine, using its own biological systems to repair and restore.
Controlling Inflammation for Faster Healing
Inflammation is an expected part of the healing process, but in dentistry, it can easily become excessive, resulting in pain, swelling, and delayed recovery. LLLT helps regulate this process by reducing the production of inflammatory mediators such as prostaglandins and cytokines, while improving local circulation and lymphatic drainage. This allows the body to clear waste products more efficiently and decreases tissue irritation. The result is a calmer, less inflamed surgical site, with patients experiencing more rapid relief and a noticeably smoother post-op recovery.
Supporting the Oral Microbiome
Recent research also suggests that LLLT may contribute to maintaining a healthier oral microbiome. The therapy appears to reduce harmful bacterial activity without disrupting beneficial flora, allowing for a more balanced and resilient microbial environment. By improving tissue health and supporting a well-regulated immune response, the laser helps protect against infection and encourages healing that works in harmony with the body’s natural biological defenses. This represents a shift away from approaches that rely solely on antimicrobial agents and toward strategies that support long-term tissue wellness.
Clinical Versatility: Applications Across Dentistry
Few technologies are as versatile as LLLT. In my practice, Erchonia lasers have become an integral part of many procedures. During periodontal therapy and deep cleanings, LLLT helps calm inflammation and encourages tissue reattachment, leading to improved outcomes and patient comfort. After extractions or oral surgery, patients typically report less swelling, bruising, and post-op pain, and they often heal faster than expected. When placing dental implants, I have found that LLLT promotes better osseointegration and soft-tissue healing at the implant site, thereby reducing early complications. Endodontic cases also benefit from laser application, as it reduces periapical inflammation and nerve sensitivity after root canal therapy and assists in resolving infection-related swelling. Soft-tissue procedures such as gingivectomies, frenectomies, and cosmetic contouring show significantly faster healing when LLLT is included in the protocol. This is especially beneficial in pediatric and infant cases, such as tongue-tie releases, where minimizing post-op discomfort is critical. Even orthodontic patients experience less soreness and sensitivity during tooth movement when laser therapy is used. Beyond traditional dental applications, LLLT has shown remarkable promise in treating TMJ disorders and orofacial pain. Patients who struggle with chronic joint inflammation or muscular tension often experience meaningful relief and improved jaw function.
The same mechanism that reduces inflammation also accelerates the healing of aphthous ulcers and cold sores, often providing immediate comfort and shorter healing times. Additionally, in sleep apnea and airway therapy, laser light can reduce tissue inflammation and improve airway tone, enhancing the results of oral appliance therapy. Wherever there is pain, inflammation, or soft-tissue trauma, LLLT offers a biologically supportive and drug-free path to healing.
There are myriad uses for LLLT in clinical cases. The images above illustrate a few examples. Figure 1 shows its use for treating TMD symptoms. Figure 2 is an example of the LLLT being used to reduce post-op pain and promote healing following extraction, bone graft, and immediate implant placement. Figure 3 shows its effectiveness when treating apthous ulcers (this image showing on the upper lip). Figure 4 is an interesting use where it is used to emulsify neck fat to help with sleep apnea and cosmetics.

Safe, Gentle, and Universally Compatible
LLLT is noninvasive, nonthermal, and completely compatible with other dental treatments. It can be used safely on pediatric, geriatric, and medically complex patients without risk of systemic side effects or drug interactions. This makes it an ideal adjunct for virtually any dental procedure, offering patients a gentle yet powerful way to recover faster and feel better. Patients consistently express appreciation that their dentist is using cutting-edge technology to protect their wellness while making their recovery more comfortable.
Better Healing, Better Dentistry
When recovery is smooth and predictable, the benefits extend to everyone involved. Patients gain confidence and trust when they experience minimal post-op discomfort. Dentists feel more confident performing procedures knowing that the risk of pain and complications is reduced. Practices also benefit from fewer emergency calls, less need for pain medications or opioids, and faster completion of treatment plans. These advantages translate into improved outcomes, more satisfied patients, and a thriving, wellness-oriented practice culture. Laser-assisted dentistry ultimately represents a win for both the practitioner and the patient.
Light-Driven Future
The field of photobiomodulation is expanding rapidly, with promising applications in nerve regeneration, periodontal tissue growth, management of neuropathic pain, and even supportive therapy for systemic conditions. Research is also exploring its potential to improve airway function in patients with sleep-disordered breathing. Dentistry sits at the intersection of multiple systems—neuromuscular, immunologic, and respiratory—and plays a central role in whole-body wellness. Tools that reduce inflammation, enhance tissue function, and support physiologic balance fit perfectly within the dentist’s responsibility to promote optimal health.
A Purpose-Driven Mission
My professional mission has always been simple: to help patients heal better and live better. LLLT enables me to fulfill that mission by combining science, technology, and compassion to genuinely improve people’s lives. When a patient wakes up after a procedure without pain, when someone with TMJ dysfunction finally chews comfortably, or when a sleep-apnea patient enjoys uninterrupted rest for the first time in years, I’m reminded why I show up with purpose every day. Dentistry touches lives—and laser therapy enhances that touch. Healing should never be a burden. With the right light, healing becomes an opportunity.
