Lasers In Dentistry -- Current Concepts May 2026

Current concepts in dental lasers emphasize a shift toward "biological dentistry"—procedures that are less traumatic and more conducive to the body’s natural healing processes. As technology advances and units become more affordable, lasers are set to become as common as the dental chair itself, redefining the standard of care through precision and comfort.

A growing trend in "cold laser" therapy involves using low-level light to stimulate cellular function. PBM is currently used to accelerate wound healing, reduce pain from TMJ disorders, and treat aphthous ulcers (canker sores). Advantages and Patient Outcomes Lasers in dentistry -- current concepts

Lasers can remove decay and prepare enamel for fillings often without the need for local anesthesia. Unlike the vibration and heat of a drill, lasers use "micro-explosions" of water molecules to remove tissue, which preserves more of the healthy tooth structure. Current concepts in dental lasers emphasize a shift

Despite these benefits, lasers are not a total replacement for traditional tools. They cannot be used to remove old silver (amalgam) fillings or shape teeth for certain high-precision crowns. Additionally, the high cost of equipment and the need for specialized safety training remain barriers to universal adoption. Conclusion PBM is currently used to accelerate wound healing,

For periodontal (gum) therapy, lasers are used to decontaminate diseased pockets and remove inflamed tissue. The bactericidal effect of the laser reduces the need for systemic antibiotics and significantly minimizes post-operative swelling and bleeding.

are highly absorbed by water and hydroxyapatite, making them the gold standard for "hard tissue" procedures like cavity preparation and bone contouring.
