Stages of Periodontal Disease

Stages of Periodontal Disease

Prevention of dental diseases in animals is one of the most important tasks of veterinary. The prevention of diseases of teeth and soft tissues of the oral cavity, is the prevention of general animal diseases, the occurrence of which is often associated with the presence of focal infection in the oral cavity. Especially the focal infection is a generation of multiple destructions of teeth, an inflammation of a mucous membrane of gums, etc.


Hygienist treatment is an active system of therapeutic and preventive veterinary dental care for animals, which allows cure not only the disease of the oral cavity but also prevent possible complications to other organs and body systems.

Depending on the veterinary school, it is customary to classify from 4 to 5 stages of dental diseases. Sometimes you can find stage 0 – this is a healthy animal with a cute snow-white smile.

Stage 1.

At this stage, the pet’s mouth is still basically healthy. However, without yet being visible, a plaque is slowly starting to accumulate. The area around the tooth shows signs of gingivitis but not any attachment loss of bone or gum tissue. Gingivitis which is left unaddressed will progress into periodontitis, a more serious inflammation, and infection.

Even at this stage, it is essential to check if calculus has already formed. A massive threat to the health of the gums, calculus is hardened dental plaque accumulated in specific areas.

Stage 2.

Having reached moderate gingivitis, this stage presents more noticeable inflammation, swelling, and sensitivity of the gums. Attachment loss is no more than 25%, with early signs of bone loss in teeth with multiple roots, and less than 25% periodontal attachment. We will advise you on starting or increasing at home dental care and scheduling a thorough Smile4Pet dental cleaning to get your pet’s dental health back on track.

As early as Stage Two, you may see signs of bleeding and pain in your pet’s mouth, including trouble eating, grumpiness if touched in the face or mouth, and reluctance in games like tug-o-war.

Stage 3.

Reaching the third stage of periodontal disease in dogs should be avoided at all costs. It implies that serious periodontal damage has already occurred, risking the pet’s overall health and greatly complicating any potential treatment.

Unfortunately, many pet owners only notice periodontal disease once it has reached this stage.

At this stage, we can still provide high-quality teeth cleaning without anesthesia.

The third stage of periodontal disease in dogs and cats implies gingivitis has progressed, becoming periodontitis. Not only are the gums irritated and swollen, but they also bleed easily. Inflamed sections of gum known as periodontal pockets are beginning to show because of subgingival bacterial invasion.

Besides producing discomfort and pain to the pet, there is evidence that bacteria originated in the mouth can affect the kidneys, liver, and heart.

State 4.

Having become established and chronic, periodontal disease in the fourth stage is considered extreme. Advanced periodontitis has taken hold, with more than 50% of attachment loss and critical bone loss.  Pets with Stage Four teeth likely require multiple tooth extractions and significant dental treatment more likely under anesthesia.

At this stage, our specialists can conduct Pre-surgical debridement’s ( Carrying out a tooth cleaning without anesthesia in advance will shorten the time required for the operation and minimize the risk of loss of the animal during surgery) or QofL Service (Quality of Life).

During Post-surgical aftercare, it is imperative to maintain the purity of the animal’s mouth. Our technicians will conduct the necessary hygiene for your pet.
