Lasers work by rendering energy in the form of light. In dental procedures, the laser acts as a cutting instrument or a tissue vaporizer. Dental lasers are used for the process of diagnosing various dental disorders with the help of laser therapy. In many cases, dental lasers obviate the necessity of crucial surgical instruments such as hand pieces, dental anesthetics, and dental drills. While using the laser for curing a filling, the laser helps to fortify and toughen the bond between the tooth and the filling material. Whereas, for teeth whitening purposes, the laser becomes a heating source and improves the effect of whatever tooth-bleaching agents have been used. Laser therapy assures less amount of traumas, lessens the amount of contamination caused due to other instruments, and reduces bleeding. The time taken for complete procedure is reduced as most of the wearisome processes are egested.
A few pros of using dental lasers as compared to conventional dental drills:
- Might lessen the patient’s level of anxiety, as a few patients are not comfortable using the dental drill
- Cause less pain in a few cases and therefore minimizes the need for anesthesia
- Reduce bleeding and swelling at the time of soft tissue treatments
- Helps in preserving the healthy tooth during cavity removal
A few cons of dental lasers:
- Lasers do not completely alleviate the need for anesthesia
- Laser treatments are much costlier than the traditional drilling methods
- In spite of the capability, traditional drills may still be needed to shape the filling, adjust the bite, and for polishing the filling
- Lasers cannot be used on teeth which already have fillings
- Lasers cannot be used to fill cavities which are in between teeth, around the areas of old fillings, and for large cavities which demand for a crown.
- Also, lasers cannot be used to eliminate silver fillings, defective crowns and/or prep up the teeth for bridges.
Laser dentistry proposes several approaches for the use of dental lasers. With the increase in the number of dentists using lasers each day, the total number of procedures which use lasers might also witness an alike growth.
