Cranberry dental gel improves oral health in dogs and cats by preventing bad breath and dental plaque buildup.

Proanthocyanidins (PACs) contained in cranberries are recognized as a natural weapon against periodontal diseases. The antibacterial, anti-adherence, anti-oxidant and anti-inflammatory properties of cranberry PACs have already been demonstrated in several studies.

Cranberry prevents periodontal pathogens from adhering to the surface of teeth to form plaque that causes most oral diseases. Thus, by preventing the formation of dental plaque, it is possible to prevent its transformation into tartar. In addition, these bacteria are also responsible for bad breath by secreting volatile sulfur compounds (VSCs). Cranberry reduces the virulence factors of periodontopathogenic bacteria, which makes bad bacteria less effective in their infection. It also has anti-inflammatory properties which reduces the gingivitis present and thus make the animal a little more comfortable. Modulation of host inflammation also reduces the destruction of tooth support tissues caused by the aggressive defense of the immune system.

The texture of the dental gel has been optimized to make it as sticky as possible on the teeth and gums of the animal to increase the contact time between the product and the oral walls of the animal. This texture makes it possible to administer the dental gel in several ways depending on whether the animal is cooperative or not. Its use with a toothbrush is the most effective method since there is the addition of a mechanical aspect. The appreciation of the taste by the animal has been an important element in the development of the dental gel to make its administration as pleasant as possible. The animal can thus make a good association with the dental gel and the owner will have more facility to do his oral hygiene.

Here is a quick overview of scientific articles that demonstrate the effectiveness of cranberry extract and, more specifically, proanthocyanidins on several factors of periodontal disease.
