The answer for this seemingly very easy question is not that obvious for a lot of people. The short answer is the following: twice per day. But there are more questions, let’s see some of them!
Which is ‘the most important’ tooth-brushing?
Of course all of them, so cleaning our teeth is important at the morning and at the evening too. But teeth-cleaning at the evenings cannot be left out because of removing plaque which formed on your teeth all day long and contains millions of bacteria. During the night the saliva production is less so the cleaning and pH level restorer function of the saliva is reduced too which enables the bacteria to spread and form tartar. Tartar in long term can lead to gum disease which an inflammation of the gums that can progress to affect the bone that supports your teeth.
