Besides causing problems ranging from cavities and bad breath to severe periodontal disease, dental 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 develop. Your pet may also not feel well in general (if you've ever had a toothache, you know how it can affect your mood!). In addition, diseases related to dental health conditions can shorten the lifespan of your pet and cause them significant pain.
This is why regular pet dental care is so essential to animals' physical health and wellbeing.
