Scientists and inventors never tire of surprising us with a variety of novelties that make our life easier. For example, one of the latest developments is ultrasonic
Principle of operation of an ultrasonic brush
The device uses a specialenergy-saving motor, thanks to which electrical energy is converted into mechanical energy with an efficiency of more than 90%. Under the head of the brush is a piezoelectric plate, which performs this conversion function. Also on it there is an indicator that shows that the ultrasound is working. It is necessary to ensure that no
Under the influence of ultrasound, the bristles oscillate withfrequency up to 100 million times per minute, due to which bacterial chains are destroyed. Ultrasonic toothbrushes have different modes of operation: soft and intense. When using an ultrasonic brush, pleasant warmth is felt in the mouth. This heat expands the blood vessels and improves blood microcirculation.
Ultrasonic brush with ease can cope withfood and tobacco plaque on the teeth. Also, it promotes the assimilation by cells of the enamel of useful microelements that are part of balms and toothpastes.
What is the main difference between an ultrasonic toothbrush and an ordinary toothbrush?
Gentle and gentle cleaning of the mouth, highHygiene are the main advantages of an ultrasonic toothbrush. Vibration of ultrasound helps to "whip" the substance from saliva and toothpaste, which will actively fight the plaque on the teeth. The ultrasonic toothbrush is able to clean the plaque on the teeth hundreds of times better than a simple hand brush
Minuses of ultrasonic brushes
Despite a lot of advantages, ultrasonictoothbrush damage can also cause. For example, it reduces the life of crowns, seals, veneers. Ultrasound promotes the destruction of demineralized areas of tooth enamel. It is also possible to awaken chronic foci of inflammation in damaged teeth. The ultrasonic toothbrush can cause an exacerbation of some inflammatory diseases of the oral cavity.
This device is not recommended for usepeople with pacemakers and pregnant women. Despite the ability to effectively remove plaque, the ultrasonic toothbrush can not cope with even the smallest hard deposits on the teeth, so you will still have to undergo a cleaning session with the dentist.
