Wife is a Dental Hygenist. Here's her "basics".

1. Brushing often is good.
2. Brushing ISN'T enough.
3. You MUST floss and scrape/brush the tongue.
4. Thourgh rinsing is good.
If bad breath doesn't go away, see your Dentist. You may have decay or another condition that can/should be treated.
5.Get your teeth cleaned at least twice a year. If you live near a community college that has a Dental Hygene program, you can get cleaned for little or nothing.
6. Stuff like crowns is expensive, even with insurance. Do your Preventive Maintnance.
