Laser treatment of caries is a rather young technique, but already quite in demand, despite its rather high cost. Probably, even a long time before dentistry was formed into a separate professional sphere, mankind began to dream of how to treat teeth without pain. Now dentistry can be safely called a high-tech and high-tech medical field, with the advent of laser equipment, many people have ceased to be afraid to visit dentists.
Therapeutic procedures are carried out by “cold” laser equipment, which emits electromagnetic waves with a certain length. They have low penetrating power, so tooth tissues are not exposed to deep heating. Water molecules absorb electromagnetic waves so intensely that this process contributes to its instant boiling. The water content in the human body is almost 70%. The enamel of teeth contains 13%, dentin – 25%.
During intense boiling, non-stop microexplosions occur that tear hard dental carious tissues at the cellular level. Therefore, they peel off without difficulty, the cut off parts are removed from the cavity with a cool water stream. Destructed carious cells are characterized by a high water content, and a cool stream does not allow excessive dehydration. Therefore, the process of removing foci of caries for healthy areas takes place without any difficulties.
Advantages and disadvantages
Laser treatment of caries has several advantages over traditional, mechanical methods of treating teeth:
- the procedure does not cause pain, is gentle, there are no unpleasant effects;
- there are no complications after therapy;
- the laser is sterile;
- during treatment, the tooth heals;
- the duration of the procedure does not take much time;
- using this technique, periodontal disease, cysts can be cured;
- the laser has an antibacterial effect;
- spot work can be done;
- the vascular walls are not affected.
For the treatment of pathology in relation to the surface and middle part of the teeth, pain relief is not required. Laser equipment does not make buzzing sounds that scare not only children but also adults. In addition, there is no “concussion" of the head as from a standard drill. This is especially important for people who have a very sensitive nervous system.
There is one drawback with modern borustan tools that untwist diamond nozzles up to 350,000 revolutions per minute – they contribute to overheating of hard tooth tissues, which almost always leads to inflammatory processes. Thanks to the chilled water stream, low penetrating power of electromagnetic waves, the possibility of such negative consequences is eliminated. There is also no rough mechanical effect, so microcracks on the enamel do not occur.
All harmful microorganisms that can get on the tooth surface lose their ability to multiply and undergo destruction. By the way, under the influence of antiseptic drugs, about 25% of foci of localization of caries die, and in 1 min. laser irradiation comes 100% sterilization. In this case, infected dust is not sprayed, and sterile cavities become more resistant to the occurrence of repeated, recurrent carious processes.
After cleansing with a laser, the tooth cavity is rough and porous. This is the best option for good adhesion with filling preparations. Due to the effects of laser electromagnetic waves, the tissue being prepared receives an additional positive therapeutic effect. This contributes to increased microcirculation of the dentinal tubules, stimulation of resistance to caries.
This procedure is one of the most sought after. Many people laser their teeth. Some dentists are, to put it mildly, not professionals. The frequent consequences of treatment in such pseudo-specialists are serious complications. Due to the high cost of equipment, the specifics of acquiring licensed documents and permission for this activity, its use by non-professionals is almost impossible.
Since laser treatment of caries does not have any negative effect on the human body, we can safely say that there are no drawbacks to this technique.
Laser dentistry is used in some procedures, including with its help it is possible to carry out correction of frenum of the lip and tongue. An effective technique for correcting the gingival margins and removing benign neoplasms. All those procedures that are carried out with a scalpel are now easily performed using laser systems. The equipment is not harmful, it does not emit negative rays.
Laser anticaries therapy, which excludes surgical intervention and tactile contacts of the jaw of a person with the hands of a specialist, proves that the procedure is harmless. During surgical interventions, a slight blood loss occurs. In the case of laser treatment, it is minimal. Rehabilitation after the procedure, complete healing and recovery are much faster than after standard surgical procedures.

How is the treatment
Before the procedure, the doctor diagnoses the oral cavity, makes a diagnosis and only after that begins treatment. If necessary, anesthesia is performed. Then carious teeth are cleaned of plaque using an ultrasonic skeller, or a special air-abrasive technique. The principle of operation is similar to sandblasting. In the same way, the carious cavity is cleaned of softened decays of the former hard tissues of the teeth.
The radiation power depends on the density of the treated tissue. Reduce it, approaching the pulp. After the formation of the cavity, the surface of the teeth, they are coated with special adhesive systems that protect the exposed dentinal tubules and improve the adhesion of composite filling materials. In the future, experts conduct restoration modeling, subsequent processing.

What safety measures should be followed
Laser treatment can only be carried out by specialists who have completed specialized courses. A rubber dam, saliva ejector must be installed in the medical office so that the evacuation of the infected chilled fluid passes quickly. The doctor and assisting medical staff work in special glasses. The patient also needs them. Work is carried out only in bright light.

Treatment during pregnancy and childhood
When a woman carries a child, any intervention is not advisable. Examination of the oral cavity should be carried out before the onset of conception. If treatment is an inevitable process, then it is advisable to carry it out in the II trimester. The use of laser therapy does not require anesthesia. The only discomfort that may occur is mild colic. Therefore, laser treatment is recommended for dental treatment in children. The procedure is silent and does not cause negative emotions in children.
In childhood, we are not able to really assess the situation and perceive the arguments of parents in favor of health. For a child, the main thing is the absence of pain and fear. Going with a child to the dentist is a whole problem. It is the laser equipment that makes the treatment comfortable. The tooth tissue in children is fragile. Work with her can be called jewelry. It is the laser rays that act gently on the teeth, destroying carious tissues without damaging healthy areas. Dentists claim that it is possible and necessary to treat children’s teeth with this technique.
Laser therapy due to the high cost of the equipment has a high cost. But it is important to remember that after the application of the method, relapses of the disease do not occur, the fillings hold very well and for a long time. Therefore, in order not to go to the dentists after some period of time, it is better to give preference to an expensive, but effective method of treatment.
