To get rid of gingivitis, will this work?

If I brush with Crest Total 3-5 times a day, floss 1-2 times a day, rinse with salt water 2 times a day, rise with a mouth wash 2 times a day, and rubbing my gums a bit. Will this reverse gingivitis alone. I am committed to get rid of it before my next dental checkup in a few months. I want to rid of this so I can focus on whitening (and protection of course). Is there any other products I should consider? Thankyou :).
