Gingivitis is inflammation of the gum tissue resulting in redness and swelling, most commonly caused by dental plaque. Plaque results when bacteria normally found in the mouth mix with proteins and starches found in saliva to produce a gritty material that adheres to the teeth. Plaque eventually turns into tartar, which accumulates on the teeth, especially at the gum line. Local irritants and some diseases, such as plasmacytic gingivitis and trench mouth, may also cause gingivitis.
Gingivitis can lead to periodontitis or inflammation around the tooth root, which in turn can lead to tooth loss.
What to Watch For Red or swollen gums
Diagnostic tests are needed to recognize gingivitis and exclude other diseases. Tests may include: Your veterinarian will take a complete medical history and perform a thorough physical examination including a thorough oral examination of your cat. Sedation or anesthesia may be needed for a complete oral examination.
Complete periodontal probing and dental charting are important to gauge the severity of the oral cavity disease and follow its progression or response to therapy. General anesthesia is needed for a thorough oral examination and periodontal probing. A metal probe is used to check the interface of the gum and tooth. This procedure is very similar to that used by dental hygienists to evaluate human patients.
A plaque dye test may be done. In this test, a red-colored liquid dye is placed on the teeth. The plaque takes up the dye and the extent of plaque can be seen easily. This dye used is referred to as "plaque-disclosing solution."
Additional diagnostic tests may include:
A complete blood count (CBC or hemogram), serum biochemistry tests and urinalysis may be performed to evaluate the general health of your cat before sedation or anesthesia.
Full mouth X-rays are important to evaluate your cat's teeth. Seventy percent of the tooth structure is below the gum-line and periodontitis cannot be properly diagnosed without them. These X-rays also will disclose more serious problems such as tooth root abscesses.
An FeLV test may be recommended in cats with chronic gingivitis.
In cats with chronic non-responsive gingivitis, a biopsy may be recommended.
Ultrasonic scaling, which is cleaning the teeth both above and below the gum-line, and tooth polishing will arrest and reverse gingivitis.
Home Care and Prevention
Daily brushing of the teeth can be effective. Brushing your cat's teeth on a daily basis can be just as effective as brushing your own teeth. Soft toothbrush
Dental care diets or treats can be helpful to maintain a healthy mouth. Chlorhexidine rinses or toothpastes can effectively remove plaque above the gum-line.
Follow-up with your veterinarian as directed, usually every 3 to 6 months, is necessary for re-evaluation. In difficult cases, you may be referred to a veterinarian who specializes in, or has a special interest in, dental care. Semi-annual to annual dental cleaning by ultrasonic scaling also may be recommended.
