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.
Dentists recommend you do it twice a day: after breakfast and just before bedtime â unless you've just had something acidic. It's best to avoid eating or drinking after you brush at night, as the toothpaste will cover your teeth with a thin layer of fluoride, which will help strengthen your teeth while you sleep. And remember to floss daily to remove food and plaque bacteria from in between your teeth, where your toothbrush can't reach.
