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.
