IPA: /ˈɡʌm.laɪn/

The area where the gums meet the teeth in the mouth.
The dentist examined the gumline for any signs of disease.
Gumline → The word is formed from "gum" (from Old English "guma", meaning the fleshy tissue in the mouth) and "line" (from Latin "linea", meaning a line or boundary). The term "gumline" refers to the line where the gums meet the teeth, marking a boundary in the mouth.
Think of the 'gum' as the fleshy tissue in your mouth and 'line' as a boundary — the gumline is the boundary where your gums meet your teeth.
