Most of the people I know say you should brush your teeth in the morning and at night before you go to bed. Is that really the best time? What if you do not sleep much the time between night and morning may only be 4 – 5 hours so that in the morning you have a long time different before you may brush again. I do not know if that seems like the best thing to do in that case. Also do we only brush for 2 minutes? everyone say we need to brush for only 2 minutes. Is that true what do you think?
