Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | neutered | 14 lbs

My cat has a dark line in his gums above the back teeth, is this a sign of gingivitis? His diet is nature variety pride tuna formula and orijen kibbles as occasional treats and I weekly rub cet virbac beef flavored toothpaste with my finger because using a brush freaks him out. How else can I help his gum health?

Gingivitis presents as redness and swelling of the gums. The black line you see may be tartar on the tooth itself or, if on the gum, natural pigmentation. You can try a small fingerbrush that may be tolerated a bit better. Daily brushing is recommended for maximum benefit. If he is a chewer, you can provide various chew toys and chewable treats.
