What Is Photobiomodulation (Red Light Therapy) and Is It Safe for Children?

Parents are increasingly asking about red light therapy, also known as photobiomodulation (PBM). You may have heard about it for muscle recovery, inflammation, or healing in adults. Naturally, many parents wonder whether photobiomodulation is safe and beneficial for children.

At Shadelands Pediatric Dentistry in Walnut Creek, we use photobiomodulation as part of an integrative approach to support healing, comfort, and nervous system regulation in children. This therapy is gentle, non-invasive, and supported by a growing body of scientific research.

What Photobiomodulation Is and How It Works

Photobiomodulation (PBM) is a therapeutic approach that uses low-level red or near-infrared light to support the body’s natural healing processes. Unlike surgical lasers, PBM does not cut, heat, or damage tissue.

Instead, specific wavelengths of light penetrate the tissue and interact with cells to support energy production and cellular repair. This process has been studied in both medical and dental settings for its ability to reduce inflammation, support tissue recovery, and promote comfort.

According to the National Institutes of Health (NIH), photobiomodulation influences cellular metabolism and can support tissue healing at the mitochondrial level.

Safety of Photobiomodulation in Children

When used appropriately by trained providers, photobiomodulation is considered safe for pediatric patients. PBM uses low energy levels and does not generate heat or cause pain. Most children tolerate it easily and many barely notice the treatment.

The American Academy of Pediatric Dentistry (AAPD) recognizes the growing role of laser technologies in pediatric care, including their use for therapeutic and supportive purposes.

At Shadelands Pediatric Dentistry, PBM is used selectively and thoughtfully, always based on the child’s individual needs and overall care plan.

How Photobiomodulation Supports Healing at a Cellular Level

Red and near-infrared light interact with mitochondria, often described as the energy centers of cells. When stimulated by light, mitochondria may increase energy production, which supports cellular repair and tissue recovery.

Research published in Photomedicine and Laser Surgery and summarized by Harvard Health Publishing shows that PBM can help modulate inflammation and promote tissue repair without causing tissue damage. 

For children, whose tissues and nervous systems are still developing, this gentle support can be especially beneficial during healing.

Why Photobiomodulation Is Used in Pediatric Dentistry

At Shadelands Pediatric Dentistry, photobiomodulation may be used to support children in situations such as:

• Healing after procedures like frenectomies

• Reducing muscle or fascial tension in the tongue, jaw, and face

• Supporting nervous system regulation after dental treatment

• Promoting comfort during recovery

• Therapy after trauma

We use infrared photobiomodulation delivered through advanced dental laser technology, following established therapeutic protocols designed for healing support rather than cutting or ablation.

This aligns with our integrative approach, where oral health, airway function, and nervous system regulation are all considered part of whole-child wellness.

Photobiomodulation and Nervous System Regulation

One of the most meaningful benefits of PBM is its potential effect on the nervous system. Gentle light therapy has been studied for its role in supporting parasympathetic activity, which helps the body shift out of a stress response and into a state more conducive to healing.

For children who are sensitive, anxious, or undergoing functional changes related to feeding, speech, or breathing, this support can make recovery smoother and more comfortable.

The NIH has published research exploring the relationship between photobiomodulation and nervous system regulation.

Clinical Photobiomodulation vs At-Home Red Light Devices

While many consumer red light devices are marketed online, clinical photobiomodulation uses specific wavelengths (we use the Fotona Lightwalker for a 1065nm wavelength), dosages, and protocols guided by professional training and research.

In a clinical setting, PBM is delivered with medical-grade equipment and tailored to the child’s anatomy and treatment goals. This distinction is important for both safety and effectiveness.

The World Association for Laser Therapy (WALT) provides guidelines on appropriate PBM parameters and clinical use.

How PBM Fits Into Whole-Child Care

Photobiomodulation does not replace dental treatment, therapy, or home care. Instead, it serves as a supportive tool.

At Shadelands Pediatric Dentistry, PBM may be used alongside:

• Preventive dental care

• Myofunctional and airway-focused support

• Post-operative stretches and guidance

• Neuromodulation of the autonomic nervous system via cranial nerves

• Collaboration with other pediatric providers

This layered approach helps children heal comfortably and adapt more effectively to functional changes.

A Gentle, Integrative Approach to Pediatric Healing

At Shadelands Pediatric Dentistry in Walnut Creek, we believe pediatric care should support the whole child, not just the teeth. Photobiomodulation is one of the ways we help children feel safe, supported, and comfortable during healing.

If you have questions about red light therapy or wonder whether photobiomodulation may be appropriate for your child, our team is always happy to discuss options and answer questions.
