As the calendar ticks off yet another year, one’s thoughts naturally turn toward goals that went unaccomplished during 2007. Of course, many of us set resolutions in an attempt to kick the new year off more productively than the last, but unfortunately, too many lack the resolve necessary to maintain those resolutions year-long: although weight loss is perennially the top new year’s resolution by a wide margin, the majority of people who sign up for gym memberships in January last only an average of six weeks before letting their often-pricy memberships lapse into inactivity.

This year, why not instead make a resolution that will most likely take up no more than an extra minute or so each day and cost you only a couple of dollars while improving your health and producing visible, lifelong results? Americans spend an average of 47 seconds brushing their teeth at each session — nowhere near the recommended two-minute minimum — and replace their toothbrushes only half as often as suggested by dentists.

Next time you’re at the store, pick up a fresh batch of soft-bristled toothbrushes for yourself and your family, and as much as you may want to cut corners in the morning, force yourself to brush for a full two minutes before running out the door. Toothbrush manufacturers, ever-quick to jump on new trends, now market both electric and manual toothbrushes with two-minute timers built right in for your convenience, but a standard kitchen egg timer placed on your bathroom counter can serve the same function. One tip: make sure you turn off the faucet while you brush. Not only does the running tap needlessly waste precious water, studies show that leaving the tap on often leads to rushed brushing.

By practicing proper dental hygiene, your family can enjoy the benefits of bright, healthy teeth throughout 2008 and for years to come — and avoid guilt over letting that gym membership card collect dust.
