Brush your teeth at least a couple of times a day, once in the morning and most especially before bed. And it is just as important to clean between teeth by using dental floss or an oral irrigator. If you have questions, ask your dentist or hygienist about when would be the best time for you to brush.
It is important to brush your teeth twice a day with a fluoride toothpaste. One of those times should be before going to bed to remove all food particles from teeth and prevent the length of attacks by food on teeth. Using a rinse after brushing can help freshen breath and prevent tooth decay.
