Lasers In Dentistry -- Current Concepts Apr 2026

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.

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

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 Lasers can remove decay and prepare enamel for

At the heart of dental laser application is the concept of . Different laser wavelengths are absorbed by specific "chromophores" in the mouth, such as water, hydroxyapatite (the mineral in teeth), or hemoglobin. PBM is currently used to accelerate wound healing,

are primarily absorbed by hemoglobin and melanin, making them exceptionally efficient for "soft tissue" surgeries, such as gingivectomies, where they provide simultaneous cutting and cauterization. Current Clinical Applications

The use of lasers in dentistry has transitioned from a futuristic novelty to a cornerstone of modern clinical practice. By utilizing focused light energy, lasers offer a minimally invasive alternative to traditional mechanical tools like the high-speed drill and the scalpel. Current concepts in dental laser technology revolve around increasing patient comfort, enhancing precision, and promoting faster healing through the targeted interaction of light with biological tissues.
