The main reason why we brush our teeth is to remove plaque. If not removed, it can lead to cavities and gum diseases. The question is, how many times a day should you brush your teeth?
Quick Fact: Studies show that plaque will regrow on completely clean teeth within three to four hours of brushing1
Going by the quick fact, it appears that we should be brushing three times a day, or at the very least twice a day. This will help to ensure that you keep the plaque to a minimum, which will promote better oral hygiene, but don't forget to floss as well.

P.S. Every individual is different so it is important to get your dentist involved in your dental care. Also it is recommended that you visit the dentist every 6 months for professional cleaning because there is only so much a piece of toothbrush and floss can do

Plaque: Plaque is a sticky, colorless film of bacteria and sugars that constantly forms on our teeth. It is the main cause of cavities and gum disease, and can harden into tartar if not removed daily.2
Tartar: Tartar, also known as calculus, is plaque that has hardened on your teeth. Tartar can also form at and underneath the gumline and can irritate gum tissues. Tartar gives plaque more surface area on which to grow and a much stickier surface to adhere, which can lead to more serious conditions, such as cavities and gum disease. Tartar is also more porous, therefore it absorbs stains more easily.3
