Basic Grading Examples of Periodontal Disease in Dogs and Cats

At Houston Pet Dental, we've seen it all, including periodontal disease in its various stages. Periodontal disease is the infection and inflammation of your pet’s gums and the surrounding tissue caused by the buildup of plaque when your pet eats. There are 4 main stages of periodontal disease that may affect your pet and we're here to show you what periodontal disease might look like throughout each one. Below, you'll find a series of photos of what periodontal disease looks like throughout each stage and the treatment options for each.

Stage 1: Gingivitis

The first stage of periodontal disease, known as gingivitis, is initiated by a buildup of plaque around your pet's teeth and gums after they eat. This accumulation of plaque leads to redness and swelling, which may be difficult to notice.

Stage 1 Treatment Options

With our comprehensive dental care services, including (routine) professional teeth cleanings and scaling as well as daily at home brushing between appointments, gingivitis can be reversed. (This will keep your pet comfortable and minimize risks as they age)

Stage 2: Early Periodontitis

If left untreated the buildup of plaque on your pet's teeth can turn into tartar. This may cause your pet's gums to recede and create pockets that may gather additional bacteria and worsen the infection and inflammation.

Stage 2 Treatment Options

In addition to a professional teeth cleanings and scaling, we will perform scaling below the gumline to help treat any pockets that may have formed.

Stage 3: Moderate Periodontitis

When the infection and inflammation progresses further into the gums removing protective bone, your pet will develop moderate periodontitis.  Their teeth may become loose exposing nerves resulting in pain.  These pets will continue to eat routinely in order to survive (regardless of oral discomfort and pain).

Stage 3 Treatment Options

Periodontal therapy* including periodontal surgery will ONLY be successful if clients can commit to consistently administering home dental care. Extractions are indicated if patient compliance is low.

Stage 4: Advanced Periodontitis

By stage 4, your pet’s gums, teeth and bones have likely suffered severe damage and may be at risk of falling out. The infection can also easily spread to other parts of the body through the bloodstream and affect vital organs such as your pet’s heart, liver or kidney.

Stage 4 Treatment Options

Our team will examine and evaluate your pet’s mouth and oral health, and may recommend surgical extraction if the infection has progressed enough. We will also provide pain medication to help keep your pet comfortable during surgery. While an extraction may sound serious, (our patients feel far more comfortable once the source of pain is removed,). Our pets do not miss having diseased painful teeth!
