Learn more about Gum Disease in dogs

Gum disease, also known as periodontal disease, is a common and serious issue in dogs.  

It is caused by the accumulation of dental plaque and tartar on the teeth, which triggers inflammation. Periodontal disease affects canine teeth and the surrounding structures (the gums and bone). It can result in gum infections, bone loss and, if left untreated over time, the loss of teeth and other serious health problems.  

Certain breeds are predisposed to periodontal disease due to poor dental hygiene, a maligned bite, genetics, and/or the shape of a dog’s mouth. Generally, these are small, toy, or flat face (brachycephalic) breeds.
