Question: I brush my teeth once a day I really do not see the need to do some more often.

Answer: It is advise that a person should brush their teeth at least twice a day. once in the morning and once at night.  By brushing your teeth in the morning you are killing germs left in your mouth and fighting not only plaque build up but bad morning breath.  By brushing your teeth at night you are removing food debris that was left on your teeth by eating throughout the day.  Also it is very important to make sure  your dental care habits do not stop at brushing. You need to floss at night every day too if you want to  maintain good dental habits and healthier teeth and gums.
