Many of us ask the same question - how to clean teeth properly? Do I clean my teeth properly? Let's try to understand how to do it. First of all hold the toothbrush under the angle of 45 degrees towards the gums. When cleaning the upper teeth direct the movements of the toothbrush down and vice-versa (when cleaning the lower teeth - direct the movements of the toothbrush up). To clean the outer surface of teeth make the movements short. It is desirable to clean not more than 2 teeth at a time. Don't press the toothbrush too hard. Do not forget about the inner surface of teeth excluding the front teeth (in this case hold the toothbrush vertically).
Remember that one can clean his teeth with an ordinary brush as good as with the electric one. The main advantage of an electric toothbrush is that it works in the initially given rhythm and does not get tired unlike people.
The first idea of creating a toothbrush of that kind appeared in 1880, the first prototype was introduced in Switzerland after the Second World War In 1961 the first wireless variant appeared. The modern variant suitable for mass production appeared at the end of the twentieth century.
In was clinically proved that an electric toothbrush has a series of advantages. First of all it maintains the constant level of bristles movement irritates the gums less, decreases the wear of tooth tissues. Secondly, it is easier to control the time of cleaning the teeth.
A good example of such toothbrush is Oral B Braun Professional Care. This toothbrush has replaceable attachments that can be selected for each family member individually and are kept in a special easy-to-use container. This kind of a toothbrush has a special timer signaling every 30 seconds. It has a compact accumulator that will allow you to use the toothbrush for many years. The bristles of the toothbrush have indicators which would remind you to change the replaceable attachment in time.
Nowadays there are electric toothbrushes that can generate vibrations of the head and bristles of ultrasonic and sonic frequencies. Sonic toothbrushes generate visible vibrations and have distinctive sound. Their oscillation frequency is 20000-30000 movements per second (250-500 hertz). The vibrations generated by the ultrasonic toothbrushes (1,6 millihertz) can be neither seen nor heard. Effectiveness of such toothbrushes is based on the vibration of the head and bristles that creates liquid microcirculation. It washes the dental calculus out.
There is another series of advantages of supersonic toothbrushes we are to mention. Firstly, they neutralize bacteria even 5 mm below the gum line. Secondly, they reduce gingival hemorrhage, decrease inflammation and promote dental calculus removal. That is why such toothbrushes are recommended to patients with orthodontic appliances, fixed orthopaedic construction, implants and parodentium diseases.
To achieve the best result in the mouth cavity hygiene do not forget about the toothpaste. If you have dental calculus try to use toothpaste to slower this process. Chemical substance used in such toothpastes (like pyrophosphates) prevent calcification. It slows down the process of dental calculus formation.
