my cats breath is SOO BAD! and her gums are slightly red but she shows no discomfort, should i be worried?

i read that it might be a sign of gingivitus? but she doesnt show any discomfort when she eats or drinks…im planning to start brushing her teeth since i am worried and i cant stand her FUNKY BREATH! i feed her soft cat food…any tips or suggestions to brushing her teeth? and should i be really concerned about her bad breath/redish gum problem?
