*You should brush at least twice a day. *A soft bristled tooth brush is recommended because the bristles can flex more than a hard bristled brush. *The "proper" brushing technique they taught us in school is the "modified bass technique" when I'm sure you can find videos of. *You should floss at least twice a day before brushing. I know that it is hard and sometime unrealistic. *If its hard for you to floss at night right before bed because you are tired try to floss earlier in the day some flossing is better then none. *Make sure when you are flossing you are not just sticking the floss between your teeth. You have to actually try to scrape the yucky stuff off your teeth. *Bleeding gums is actually caused by not flossing enough, the more you floss the less bleeding you will have. *Using a mouth wash twice a day can also help kill germs that cause bad breath. But if you use a mouth wash that has alcohol it can dry out your mouth.
You should also brush your tongue and roof of your mouth.
Floss, brush, and rinse at least twice a day after meals. Use a soft bristle toothbrush or an electric toothbrush :)
