Best thing I've found for oral hygiene is a Water Pik. It will really flush out your gums. Use lukewarm water, tap cold is painful at least for me. You can put some mouthwash it it too if you like.

Since I've been using one my dentist has remarked on the noticeable improvement in my gum health.

EDIT: This is in addition to regular brushing of course.

I second (third?) this. You can also use a ViaJet (some people prefer it).

You can use salt and/or baking soda as antibacterials in the water you use for irrigation.

If you add irrigation to your routine, you may want to switch out dental floss with dental tape and "buff" your teeth (floss:tape as thread:ribbon - buffing with a thread doesn't work too well). Makes a huge difference in the buildup of plaque.

Lastly, disclosing tablets or solution (picking one at random from amazon: http://www.amazon.com/dp/B000W6LW6I) is not just for kids. Using it for a few weeks or months could help you see where your tooth brushing technique is a bit weak.

I second this. I floss, but sometimes laziness wins and water pik works remarkably well, followed by brushing.
