What is the gingival index?

The gingival index is used in dental care to assess the extent of gum disease. A dental professional uses visual analysis to assess the gum tissue surrounding each tooth on a scale of one to four, with four representing significant periodontal disease. This index can help dentists create a plan of care for patients and explain the extent of gum disease in an understandable way. It can also be used to track the progress of dental treatment over time.

The gum tissue is tested with dental instruments to determine the extent of gingival bleeding. While some bleeding is typical during dental exams, significant bleeding can be indicative of gum disease. The dentist also takes into account the color and firmness of the gums. Red or purple gums indicate periodontal disease. Soft and tender gums can also be a sign of gingivitis.

While the gingival index uses a scale of one to four, the difference between a rating of one and two and three and four is not the same. This makes the index somewhat subjective, and the values ​​given may vary slightly from one professional to another. The same dentist should perform the analysis during subsequent dental visits to ensure reliability.

The numbers from each gingival pocket can be averaged together to give an overall representation of gingival health. Many dentists use the gingival index at the beginning of a patient's first visit to get a concrete overview of that person's dental health and to provide a baseline for comparison at future visits. The scan typically takes about five minutes.

Each score on the gingival index describes a particular state of gum health. A rating of one represents normal gums with no bleeding after probing or discoloration, while two indicates minor change in gum color and minor swelling, but no bleeding. Three represents moderate redness, swelling, and bleeding on probing. Four indicates moderate to severe swelling and bleeding without pressure, significant color change to deep red or purple, severe swelling, and possible ulceration.

Gingivitis, or gum disease, is a very common dental problem and has many causes. Signs of gum disease include bleeding gums with daily brushing, red or purple gums, swollen gums, tenderness, and mouth sores. Known causes of gingivitis include diabetes, poor oral hygiene practices, illness, and pregnancy. It is possible to reverse or reduce the severity of periodontal disease. Regular and thorough dental cleanings, home flossing, mouthwashing, and realigning your teeth can help treat gingivitis.
