Electric toothbrushes: types and types of structures, the principle of operation, reviews of dentists and patients
Electric toothbrushes are far from being a novelty in the modern market.Moreover, every year manufacturers improve models and create new types and types: ultrasonic, with 3D technology and the like.But until now this know-how causes a lot of controversy and doubts about its usefulness and quality of purification.
Manufacturers of brushes claim their high efficiency, save time for consumers and better tooth cleaning.Dentists are not so enthusiastic about them respond, and some are rather skeptical.
Let's consider all the pros and cons of this device, the principle of its operation and how to use electric toothbrushes correctly.Feedback from experts in dentistry is very important when deciding whether or not to use an electrical analog.
Types of electric toothbrushes
The main types of electric brushes today can be called:
- return-rotational;
- combined;
- ultrasonic.
Combines them that they work from electricity, where the name came from, specifically from finger batteries or a network adapter.Of course, each of these types has varieties, with every year there are various new items, for example, rotational-return with 3D technology, combined are with different attachments( CrossAction or Dual Clean) and the like, but the principle of their operation is usually similar in theirType.
Return-rotary have a circular head, which combines movements in a circle in different directions, with the help of which it loosens and sweeps the plaque from the enamel of teeth.
In the combined, except the cup-shaped head, there are additional static cross-bristles that provide greater access to the surface of the teeth.
The head of the ultrasonic brush resembles the usual manual, and the purification is due to the vibrations of the bristles at high frequencies( the piezoceramic plate located under the bristles emits an ultrasonic wave, due to which its action extends to hard-to-reach spaces in the teeth).
Ultrasonic Toothbrush
The appearance of an ultrasonic toothbrush has produced some boom in the world of electrical models.Manufacturers argue that its use of can replace the procedure for cleaning the teeth of with special equipment from a dentist and even that now you can almost cancel your trips to a doctor or at least reduce the number of visits.This, of course, affects the popularity of this product among consumers, because the trip to the dentist rarely causes positive emotions.
However, dentists themselves are very critical of such statements, moreover, advise patients to beware, since has a number of contraindications to for the use of such electric toothbrushes.
In addition to the fact that such a brush mechanically removes dental plaque due to vibrations of the bristles, the ultrasonic waves of do not allow the microbes to attach to the surface of the teeth.Also they quite effectively remove a soft pigmentary scurf.
In general, consumers of such brushes are satisfied and reviews leave mostly their positive.
Excellent polishing and whitening of teeth, good pulls in hard-to-reach places and in principle inexpensive.Disadvantages can be called what is quickly discharged, and the nozzles need to be changed as often as the usual toothbrush and here they are just not cheap.
And indeed, with light neoplasms on the teeth, such brushes are quite easy to handle, but even with small hard deposits on the teeth, it will be much harder to cope with.If you have extensive hard deposits, it will not help you at all, then needs to undergo the dental procedures of with a doctor.Therefore, to argue that electric toothbrushes replace the reception at the dentist still can not.
Electric toothbrushes, especially ultrasound, are not recommended for use in people with various gum disease and teeth, as well as with fillings, crowns and dentures, as they can cause a number of unpleasant effects, such as:
- rupture of fillings and crowns or reduction of their service life;
- destruction of tooth enamel in areas with small mineralization;
- exacerbation of chronic periodontitis;
- exacerbation of periodontitis and gingivitis.
Impact of electric brushes on sealed teeth
The electric brushes are designed to remove plaque and soft dental deposits.In particular, ultrasound does this with the help of waves that penetrate through the tooth tissues and remove all unnecessary.But the fact is that crowns, seals, various inserts and metal pins in the canals of the tooth are made of artificial material, which in their physical properties are very different from the tooth tissues.Accordingly, the vibration of such fabrics, which are created by electric brushes, and the vibrations produced by the artificial materials of the seals and crowns, will differ that can create a conflict between media and at the interface between the material and the tooth tissues.
Such a conflict will cause the destruction of the connecting material, the so-called adhesive( adhesives, cement, etc.), which connects the seal or crown to the hard tissues of the tooth and, accordingly, leads to the loss of the latter.This process of destruction of the connecting material will be gradual, initially invisible to the consumer, but in the end will lead to an undesirable result.To a greater extent this, of course, refers to ultrasonic brushes, but ordinary electric ones also lead to the same result.
And indeed, on the forums sometimes you can find the reviews as follows:
The electric toothbrush was somehow presented as a gift from friends along with a large booklet on proper use.There it is written how beautifully she cleans her teeth, smashes the plaque, massages the gums and saves time, because she needs to clean her teeth only for one minute instead of three, which requires a conventional brush.But, to be honest, I could not get used to it.During cleaning, there is a constant feeling that now I have all the fillings.Now I'm glad that I did not have a relationship with her, thanks to this, I did not do even more harm to my teeth.
This can also be confirmed by dentists:
I am a practicing physician-paradontologist and have been working with ultrasound for 12 years.In his practice of removing tartar by ultrasound, there were cases of loss of substandard seals in this procedure.With a good material, the service life is reduced.
After such feedback, the question arises: is it possible to conduct ultrasonic cleaning of teeth at all?In fact, there is nothing to be afraid of, since such a cleaning at the dentist is carried out no more than once or twice a year, that will not do much harm to for your seals and crowns, but it will help prevent dental and gum disease.
Destruction of the enamel
Sometimes people can see on their teeth small white spots that can be seen with the naked eye.These are demineralized areas of enamel with insufficient calcium.In fact, is the initial stage of caries and although there are no visible signs of destruction of the enamel, it is very fragile and porous in this place.
Even an inexperienced dentist can accidentally damage this brittle layer when removing dental deposits, what can we say about the daily use of an electric toothbrush with strong rotational mechanical movements or ultrasonic with its waves?Daily use of such brushes will cause gradual destruction of the enamel of in such areas, which will lead to caries and the need for tooth filling.
If the teeth are healthy, then using any electric brushes will be completely harmless to the enamel.
Chronic periodontitis
When a periodontitis disease at the tips of the roots of the teeth, cysts are formed - pouches containing pus.This disease can occur for quite a long time not detected, without manifestation of symptoms and almost 70% of people have similar inflammation foci.The use of electric toothbrushes and, especially, ultrasonic, can lead to exacerbation of of this chronic disease, which will be accompanied by pain in the tooth, swelling of the gums, fistula formation.
Inflammatory gum disease
The use of electric toothbrushes in the acute period of gum disease( periodontitis and gingivitis) is categorically contraindicated with pains, swelling, purulent deposits, edema and bleeding, as using such mechanisms, you can spread the infection across all the teeth.Return to the use of such brushes is possible only after the cure of diseases.
It is also not advisable to use electric toothbrushes during pregnancy, especially in the first trimester.It's not for nothing that even a visit to dentists and dental treatment during this period are forbidden for women, as it can cause a spontaneous abortion.Also, doctors do not recommend women in the position to use such brushes, especially ultrasonic.
The presence in the oral cavity of benign or malignant tumors and diseases of the mucous membrane is another reason to refuse to use such brushes.
Using toothbrushes
Without the fear to use electric toothbrushes and sometimes get a positive result, in addition to oral hygiene, it is possible in the following cases:
-
lack of seals, veneers, crowns and other artificial materials on the teeth; - no deposits on the teeth( especially subgingival);
- absence of gingival diseases such as gingivitis and periodontitis:
- presence of periodontal disease.
Periodontal disease differs from other gum diseases in that inflammation occurs not due to infection or inadequate oral hygiene, but because of the process of bone degeneration.Therefore microstimulation by an electric toothbrush, and, especially, ultrasonic, will be on the contrary useful for gums.However, you must be absolutely sure that this disease takes place.
Of course, this brush has enough pluses.If an ordinary manual brush should be changed every two to three months, then the electric brush can serve you from three months to six months.Also this brush saves time , after all it is enough to clean teeth only one minute, while manual one is not less than three.
When choosing a brush, it is worth paying attention to the models of well-known companies, they are conducting quite serious studies, trying to minimize the negative possible damage from the brush and increase their efficiency.
Still, dentists' reviews are mostly skeptical, they are suspicious of electric toothbrushes and consider them a dubious invention.
In their opinion, after the increased popularity of this know-how, , the amount of damage to the enamel and gum disease has also increased, as improper use of electric brushes leads to damage to the gums and even loosening of the teeth.
If you still brush your teeth with an electric brush, try not to touch the tooth edge in the gum area.
