Unless you brush your pet's teeth after every meal or snack, bits of food and bacteria collect right at the gum line and turns into plaque. If this plaque isn’t removed, in just a few days, it will harden into tartar that sticks to your dog’s teeth.
Tartar irritates the gums, resulting in inflammation, also known as “gingivitis”. Many times this will first rear its ugly head as bad breath. In more advanced cases, tooth pulling can become necessary after the tooth is affected by the decaying area.
You can also see your dog’s gums turning from a healthy pink color at any point. This is a sign you are reaching an advanced state.
