Pets should have their teeth examined once per year. However, if your pet has had a history of teeth or gum complications, the frequency may be higher.

Not only can it cause damage to your pet’s mouth, but dangerous bacteria can get into the bloodstream, affecting major organs like the heart, lungs, and kidneys.
