I’ve been trying to explain to my preschooler why he needs to brush his teeth. Brushing and flossing are something we all learn at an early age.  The proper way to brush your teeth takes less than 2 minutes, although many people tend to spend much longer, or much less.  Most adults tend to spend less than a minute, which isn’t enough time to clean your teeth.
Some people suggest that to get the right amount of time brushing, you should try using a stopwatch while you brush. Hmm… that sounds like an interesting suggestion.
