How can we Diagnose Swollen Gums ?
The sight of the gingiva is sufficient to diagnose the condition. Bleeding of the gums, when a sharp thin metal instrument is passed along the margin connecting the tooth and the gingiva indicates inflammation.
Gingival fluid measurement test
In this test, the increase in amount of gingival fluid is measured which is not seen in a healthy gingiva. Gingival fluid is a fluid produced by the gingiva in the space between the teeth and the gingiva called gingival sulcus. Special instruments and techniques are required to measure the minute increase in the amount of gingival fluid. This is a specialized test for confirming swelling due to infection.
