Most everyone knows to brush their teeth at least twice each day,  floss daily, and visit the dentist two times a year for a cleaning and a checkup. What some people don’t realize is that you should also trade your old toothbrush for a new one every 90 days to maintain good dental hygiene.

According to the American Dental Association, both budget-friendly manual and pricier electric toothbrushes can effectively clean teeth. Whichever type you choose, Charles K. Perle, D.M.D., a spokesperson for the Academy of General Dentistry and a dentist in Jersey City, recommends looking for a soft brush with nylon bristles and rounded ends.

Need a new toothbrush? In honor of National Smile Day (June 26), hello is giving away toothbrushes to the first 5,000 people who like and register on their Facebook page. For every toothbrush given away, hello will also donate one to a family or child in need.

    I use the old brushes to clean jewelry and clean between small crevices like my keyboard (after the toothbrush has been cleaned with soap).

    Does boiling have the same benefit? I usually boil mine every 3-4 months and keep the brush for a year (as long as the bristles aren’t showing wear). It seems excessive to replace a toothbrush that often if boiling takes care of the bacteria…
