Modern devices have additional features not found in conventional, and which contribute to more correct brushing. But it is also quite expensive with prices for rechargeable electric toothbrushes to start around and can reach up tofor the most advanced electric toothbrushes with additional features. Those using simple batteries are of course much lower prices.
To help you in your choice before buying a toothbrush, then you will find information on the different types of electric toothbrushes and their prices.
How electric toothbrushes work?
An electric toothbrush as it says its name, used for the operation of the electricity automatically moves with great speed on the toothbrush head. The energy is provided by built-in batteries either rechargeable or simple.
The battery and the electronic device on rechargeable electric toothbrushes are tightly fitted inside the handle and typically operate with current 12v. The charging device is inductively with no metal contacts. When the toothbrush is positioned in charger creates a magnetic field that charges the battery by induction.
On economic electric toothbrushes with low price, the devices are not rechargeable but use simple AA or AAA batteries which are placed in a special compartment in the bottom of the handle and must be replaced approximately every two months (depending of course on the use).
Who need a toothbrush
The people who need most of all and will benefit greatly by choosing an electric toothbrush are those with mobility and dexterity problems in handling of the toothbrush (eg people with arthritis, the elderly, people with special needs, etc.) and those who for whatever reason find it difficult to apply the correct technique for brushing teeth requires the use of a conventional toothbrush.
The second major group is expected to see a significant improvement in cleaning teeth using a modern toothbrush are those hastily brushing for a short time, and those put excessive force when brushing. These individuals would benefit particularly if you obtain a model with built-in timer and pressure sensor that will help them comply with the rules of proper brushing.
Generally, electric toothbrushes are recommended for those who feel they brush more comfortable and pleasant than a conventional toothbrush. And that alone is enough to brush more often and for a longer time with beneficial effects on their oral health.
Types of electric toothbrushes
Currently on the market many electric toothbrushes of different types with a wide price range, but with significant differences between them.
Depending on the power mode discern rechargeable and battery toothbrushes.
Rechargeable electric toothbrushes have built-in rechargeable batteries that are charged when the device is in a special charging station installed connected to electricity. In this category the most qualitative market models.
The battery toothbrushes use to operate the simple AA or AAA batteries (either removable and rechargeable) are placed in a special slot in the handle. No need basis and therefore have an advantage in terms of portability, while is the most economical solution. Despite the initial low purchase cost but should be taken into account and the cost of batteries will be needed over time. They are however a good introductory choice for someone who uses simple ob / brush hand and wants to experience the feeling of a vacuum without spending a lot of money for one of the most sophisticated models. The battery supplies a small electric motor which produces the rotary motion that drives the toothbrush head.
Depending on the configuration of the head and the type of running operating, electrical toothbrushes in the following categories:
Reciprocating. The tufts of fibers are moved back and forth and forth and back essentially mimicking the movements of conventional toothbrush. It is the oldest technique employed in the first electric toothbrushes have rectangular head as simple. Today only a few low-cost models using this technique.
Rotary. With small round head with normally two fiber lines cyclically rotating in the same direction. The rotation involves the whole head but on certain models combined with independent rotation of each tuft.
Rotary bidirectional. They are the evolution of the previous similar head in which either one tuft row is moved in one direction while the other set of fibers is moved in the opposite direction, either consecutive tufts are moved alternately in opposite directions.
Rotary reciprocating. With similar rotating head but which rotates rapidly alternating with two directions (usually ½ turn to one side and then ½ turn to the other side).
Conventional pulse. Besides the rotary and reciprocating motion combine vibration of the fibers back and forth or up and down for better cleaning effect.
Sonic toothbrushes (sonic). While the typical electric toothbrushes do some 3000-7500 movements per minute, the noise ob / brushes move much faster with about 30,000-40,000 movements / min. The fibers are moved back and forth with this high speed, creating a vibration that not only dissolves the plate but also helps the toothpaste and the ingredients to penetrate between the teeth and below the gums.
Ultrasonic toothbrushes (ultrasonic). so named because they operate at higher frequencies outside the hearing range of about 1.6 MHz, which translates to 192 000 000 vibrations / minute. The vibration causes is so intense that it can clean the plate and distance of 2-3 mm that is without having to touch the brush to the tooth surface. The fact that it requires no mechanical action on the teeth makes ultrasonic toothbrush as the safest type enamel and gums.
Rotary reciprocating electric toothbrushes and the newer type of sonic and ultrasonic types are considered as are most effective and most recommended by dentists. As expected, the most modern ultrasonic electric toothbrushes have the highest rates, but you can get pretty good results of cleaning teeth even with lower price models.
