It is very easy to say how you have to brush (place the brush at 45 degrees, massage, introducing it under the gums, brushing in a circle and then drag), so we must find a way to do that each of us in the best possible way. And do it with a medium brush, NEVER with a stiff brush.
Its not enough to brush your teeth three times a day if you don’t do it correctly. Better to do it once and doing it in the proper way. Ideally, brush your teeth three times a day, after each meal (breakfast, lunch and dinner), but with our lifestyle we often don`t eat at home at noon and, therefore, we don't brush. Or sometimes we rush in the morning and we did not brush. If we don`t brush three times a day, at least do it twice (morning and night) being the night one the most important.
At night, the bacteria have more hours to work and attack the enamel, causing tooth decay or periodontal disease (gum disease). The bacteria feeds on food debris, causing acids that attack the enamel, making its destruction. In addition, at night we produce less saliva, and teeth are less protected.
Brushing is important to prevent or reduce the incidence of caries, periodontal disease prevention, halitosis, plaque and tartar, and have clean teeth.
The toothbrush must be replaced at least every three months and sooner if the bristles are open or crushed (if this is the case, you have to see that you are not doing a very aggressive brushing. This does not mean that you you're brushing your teeth properly, quite the opposite). The toothpaste has to be with fluoride to prevent decay and you have to put very little on the brush (the size of a pea), or another toothpaste if your dentist recommends it, for sensitive teeth or sensitive gums for example. Brushing your teeth should take around 3 minutes. Then you can rinse with fluoride or another rinse, depending on the needs of each person and recommendations.
Apart from the manual toothbrush, which can be soft, medium, hard, supersoft, surgical, orthodontic, children, etc.., there's the dental floss (waxed, unwaxed), interdental brushes of different sizes (both very important and necessary for cleaning between teeth, where you can´t reach with the normal toothbrush). There's also the electric toothbrush, dental shower or dental irrigator, rubber cone, tongue scraper, etc.. "Tools" are many and varied, but you must know how to use them. Your dentist can help you.
