Lasers can as cutting instrument or vaporizers of dental tissue when it comes into contact with the said tissue. Thus, it is useful of biopsies or lesion removals. It can also be used to remove dacay on or within a tooth, preparing the area for filling. Likewise, it is also used to strengthen the bond between fillings and the tooth, making it harden faster and more permanently. Lasers can also be used for reshaping gums and taking out bacteria, making it an important part of any root canal procedure. Finally, for those who want to whiten their teeth, the heat produced by lasers make the bleaching agent react quicker and better than when used with traditional dental tools.
There are different types of lasers that are suitable for every dental need. There are short-pulsed erbium:yttrium-aluminum-garnet lasers, primarily used for resurfacing of the gum, Argon lasers for curing the tooth fillings, and carbon dioxide lasers that are used for oral surgeries.
Pros of Laser Dentistry
Laser dentistry may be used as an alternative to the dreaded dental drills. Lasers cause less anxiety compared to dental drills, which some patients fear due to bad experiences in the past. Laser also causes less pain as compared to dental drills, lessening the need for anesthesia. It also causes less bleeding and inflammation during treatments of the soft tissues, and due to its precision, it can preserve healthier tooth portions during the removal of cavities.
However, it must be noted that even with FDA approval, American Dental Association has not yet given their Seal of Acceptance to any one type of dental laser just yet. Still, the ADA remains cautiously positive on the use of laser technology for dentistry purposes.
