In the first part, the topic of anesthesia and how to make it painless was discussed.
Today's post will focus on the trauma of drilling.
The first recalled moments of dental horror are visits to the school dentist, who was feared in childhood. Beware, there are patients who, due to these unpleasant memories, feel pain at the mere sound of a "drill."
However, 21st-century dentistry has a solution to this problem, and it is, of course, the erbium yag laser
The advantage of such a laser is that it can be used on the hard tissues of the body. Such hard tissues include enamel or dentin, which, simply put, is the tooth. With this laser, the dentist can remove decay without touching the tooth, thus not needing to use a drill, the patient does not feel vibrations or pain, and does not hear the unpleasant sound.
During the removal of decay using a laser, water and a beam of light are emitted from the laser, which is absorbed in this water, resulting in the process of ablation, meaning the diseased tissue is painlessly removed.
If, however, the dentist works with a laser, the process of ablation occurs, which, simply put, is an explosion. The light emitted from the laser is absorbed in the water (both the one coming from the laser and the one found in every tissue of the body), and as a result of this absorption, a water explosion occurs. Exactly then, the superficial part of the diseased tissue, i.e., decay, is removed. This entire process happens at the speed of light, which is faster than the transmission of an electrical impulse. So before the information about the pain reaches the brain, the diseased tissue has already been removed. Additionally, with the use of a laser, there is no friction, no touch, no increase in temperature, and no unpleasant sound.
So, as you can see, the nightmares about scary dentists can be forgotten, you just need to choose the right dental office:)
