Why are sonic toothbrushes preferred over oscillating toothbrushes? e main di erences between a sonic and oscillating toothbrush are the direction of the brushes’ movements, the shape of the brush heads and the cleaning coverage. Oscillating toothbrushes do not reach the interdental spaces, and the turbulence they create is directed mainly to the sides. e vibrations present in sonic technology, on the other hand, have the power to reach interdental spaces due to the hydrodynamic e ect. e overall cleaning impact on gum health – removing bacteria out of pockets and thus reducing in ammation – is therefore, according to studies, more e ective with sonic toothbrushes. e sulcus area, the transition point between the teeth and the gum, is sometimes neglected. e special thing is that with sonic brushes you can feel the entire surface of the teeth right to the edge of the gums. If the gum line is cleaned a little, it is still safe, because the bristles are very ne and comfortable and the movements of sonic toothbrushes are side-to-side, which leads to almost no injuries. An oscillating movement in toothbrushes is often destructive. But the Curaden’s Hydrosonic toothbrushes have much softer laments than the oscillating toothbrushes, and also other sonic toothbrushes. It should be noted that not all circular movement-based dental procedures are bad. Patients should be aware that dentists also perform rotating movements with their cleaning instruments – but this is very di erent. ey can fully control the movement as they have an optimal view of the tooth, and whilst they use circular movements, it is not strictly oscillating. When patients are cleaning their own teeth, however, they do not have a chance to observe exactly what the brush is doing on the tooth surface because they are missing the optimal view, and that can lead to gum injuries. In addition, the Hydrosonic pro toothbrush has the special drop shape of the brush head. anks to this, it is easy for patients to optimally adapt their toothbrush to the tooth surfaces both buccally and orally – on the side and in the front. is is possible thanks to the angulation of the brush, the shape, and also the rubberised back of the handle. Other sonic toothbrush manufacturers make the brush handles from a solid hard plastic material, so that the energy from the motor can be perfectly transferred to the brush. When vibrating, this hard handle can cause unpleasant feelings, frighten the user or even hurt the mouth. All those uncomfortable risks are lowered to the minimum with the Hydrosonic pro’s special bristles and design. What is the main advantage of sonic toothbrushes over manual toothbrushes? Many people put too much pressure on their teeth and gums when using manual brushes, which means that cleaning damage is inevitable. is is especially the case with hard-bristled brushes. Over time, this can lead to receding gums, destroyed enamel and gum injuries. Learning the proper cleaning technique with a manual toothbrush takes time and practice, and unfortunately, is not suitable for many patients with certain limitations of movement. Sonic toothbrushes, on the other hand, are extremely easy to use – even for kids or patients with braces or implants. In fact, they’re ideal for anyone who wears orthodontic appliances, or su ers from any form of motor disability. Since braces are usually equipped with wire parts and hooks, the vibration and movement of the bristles on a sonic brush, combined with the hydrodynamic e ect, makes it easier to ensure a thorough clean. Some of the bristles will stay on the braces themselves, whilst the vibration of the neighbouring bristles means they have a greater freedom to reach into the gaps and surfaces around the braces, resulting in an enhanced clean. “It is important to remember that the mouth should be closed during a cleaning with a sonic toothbrush.” It is important to remember that with a sonic toothbrush you brush without using forced pressure. e Hydrosonic toothbrush should be guided and well applied to the tooth with light pressure of only approx. 30-40 pond. For cleaning, it is advisable not to rest the brush completely on the tooth, but to make small circular movements almost in the same place, so that all parts of the tooth bene t from the bristles touching the tooth (mechanical cleaning), and at the same time from the freely oscillating bristles (hydrodynamic cleaning). A 45-degree inclination to the tooth helps clean in the sulcus in particular, which is indicated in gingivitis and periodontitis. e 90-degree brush position has a full e ect on the tooth, so the best cleaning of the tooth surface and the interdental spaces is achieved this way. It is important to remember that the mouth should be closed during a cleaning with a sonic toothbrush. e sonic toothbrush does almost all
