Can gingivitis go away in two weeks?

YES!!!: Yes! if you brush carefully twice a day(small massaging motions with toothbrush, one tooth at a time) and flossing properly before you go to sleep(slide the floss gently into the gum beside your tooth).

Also....: You can experience an amazing benefit if u either rinse with warm salt water twice a day (1/2 tea spoon in one glass 4-5 oz. Water) ...If u have high blood pressure, then instead of rinsing, you can actually brush with salt water as well.. You 'll see wonders with this natural, cheapest, most effective anti-inflammatory agent. ! good luck!

best: Because bacteria and germs are always in your mouth, the way to fight gingivitis long term is to do the best you can at homecare, with frequent, routine brushing, flossing, and adjuncts (even hydrofloss) then, you must keep up regular routine dental hygiene professional cleanings, too.
