Lasers In Dentistry -- Current Concepts Apr 2026

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.

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 in dentistry -- current concepts

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. The Mechanism of Action For periodontal (gum) therapy, lasers are used to

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 They cannot be used to remove old silver

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

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

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.
