Oral health issues and conditions can lead to disease in the liver, kidney, heart, and other areas throughout your pet's body. Cysts or tumors may form. Your pet may also be feeling under the weather in general (if you've ever had a toothache, you know how it can affect your mood!). Diseases associated with oral health conditions can shorten your pet's life and cause significant pain. This is why regular dental care is so important for the physical health and well-being of animals.
