For years, veterinary professionals have relied on a broad spectrum of antibiotics in dental care. However, the more such drugs are used, the more bacteria become resistant, rendering these methods ineffective. With the magnitude of dental cases veterinarians see, it’s clear that easier and more effective ways to fight these conditions are needed.

Several species of bacteria that cause periodontal disease, known as black-pigmented bacteria (BPB), transport haemoglobin into their bodies as an iron source (this is thought to be why they make gums bleed, by using enzymes that weaken blood vessels), and store the haemoglobin’s dark-coloured photosensitive porphyrin. Light directed at these bacteria is absorbed by the porphyrin and through a chemical reaction, produces substances that are toxic within the bacterial cell. This poses a severe risk of infection, and in extreme cases major organ damage, if not treated.

Antimicrobial drug resistance is on the rise, so the reliance on antibiotics as everyday therapy needs to be reduced. The added implication of poor owner compliance; either due to forgetfulness, not believing in the benefits of the prescription, or not wanting their pets to have any side effects (whether there are any or not), also contributes to the continued reduction in antimicrobial efficiency in the treatment for dental disease.

It’s clear that a need a new tool is needed. Something bacteria cannot fight, and a way that veterinarians can take control, providing the best possible chance of preventing and fighting this disease.

Blue light technology is the latest development in veterinary care, enabling veterinarians the best possible chance of preventing and fighting periodontal disease.
