I'm a dentist, and the best you can do is Floss at least once a day.... that will help a lot, and the next thing is you need to know the proper way to brush them, most people myself included have a section of the mouth that is harder to clean, therefore you need to visit your doctor and get a cleaning depending on your needs(once a year, every 6 month or more often) if you've had Gingivitis, you should probably need to go regularly.......
