Professional cleaning of teeth

Professional cleaning of teeth

Despite the abundance tooth-care aids, not many people can completely remove remnants of food eaten per day from the teeth. Smoking and poor oral hygiene aggravates the consequences. But the ugly grayish-yellow teeth plaque not only spoils the look, it also serves as a perfect breeding ground for bacteria that provoke caries and periodontal disease. Professional oral hygiene will help to avoid these problems.

Why do some people’s teeth remain snow-white from birth to old age, and the other people have gray-yellow teeth, despite using the most expensive toothpastes? Some people have inherited this feature, but mostly, people should blame their habits: a large amount of plaque can appear because of the habit of drinking strong tea and coffee in large quantities, smoking, and not too careful oral hygiene.

At first, plaque is soft, as dentists say, "non-mineralized", but eventually it gets stronger and hardens, turning into tartar, and what is most dangerous is that at all stages of its existence, it poses a real threat to the health of teeth and gums. Average daily care is not enough to remove plaque, even soft, so from time to time it is necessary to make "spring cleaning" in the mouth, the professional teeth cleaning.

Several methods are used for removing plaque from teeth. The first method includes the use of special fast rotating mechanical brushes with special "professional" pastes. It is a reliable and time-tested method. More and more popular today becomes the usage of devices working on the principle of sandblast machine.  

Of course, it is possible to compare it with the sandblast machine only formally. Similar are only the core principles of their actions, when a mixed stream of water, air, and the smallest and strictly calibrated particles of ash are served out of a special nozzle under pressure. The crystals at high speed hit the surface of the tooth, cleaning it. Water spray washes them with particles of removed plaque and reduces the heating surface of the tooth. The cleaning process is much faster, painless and harmless to teeth.

It is much harder to handle with tartar. Several decades ago, there was no alternative to a mechanical cleaning, when a dentist, using a special tool, just had to tear off the hardened deposits from the surface of the enamel. Of course, it did not bring much pleasant feeling to the patient, so now the mechanical method is rarely used, only in those cases when the patient, for example, cannot tolerate ultrasound.

Ultrasound is considered nowadays as the most common method of dealing with the hard dental plaque. Ultrasound Scanner can be found almost in any dental clinic. This is a very versatile machine that allows not only removing of supragingival deposits, visible to the doctor and to the patient, but also subgingival, about the existence of which we often do not suspect. In addition, ultrasound has fatal effect on the bacteria, leaving the surface of the tooth sterile. After the ultrasonic cleaning the surface of the tooth is smoother than after mechanical cleaning, but nevertheless, it is better to polish it. The smoother the surface of the enamel is, the harder it will be for the new tartar to deposit there. The disadvantages of ultrasonic cleaning include the need for anesthesia, especially in those cases when the removing of subgingival plaque is needed.

Various modes of the laser system can deal with all kinds of dental plaque: soft plaque, pigmentation (so-called “smoker fur") and a solid plaque, supra- and subgingival. Laser acts selectively on the tissues, depending on the amount of water contained therein. The plaque, even already hardened, contains much more water than healthy enamel, so the laser does not have any negative impact on it. Moreover, after the removal of plaque with the help of laser, the enamel easily absorbs fluoride, calcium, magnesium, phosphorus and other useful trace elements and nutrients contained in food or toothpaste.

Dental plaque is removed layer by layer, being crushed into tiny particles that are washed out with the usage of water spray. This impact is much gentler than ultrasound, because the laser works without contact, from a distance. Anesthesia is not required. These methods are rarely used separately to remove plaque. The term "professional hygiene" includes the removal of hard and soft plaque, and dentists often use various techniques for this purpose, such as ultrasound and professional paste, or Air-Flow and Laser, followed by polishing, and sometimes procedures of saturation of teeth with fluorine or calcium. The main factor influencing the cost of cleaning is the choice of method for removing the plaque.
