What dental procedures can be treated with lasers?
Though not commonly known, laser dentistry has been around since the 90’s. The focused beam of light energy has been found to be very useful in certain dental procedures and with significant advantages over traditional methods.
Lasers are found to be useful in a number of dental procedures. Some of our laser dentistry procedures include:● Treating gum disease.● Removal of inflamed gum tissue.● Reshaping of gums.● Elongating crowns.● Removal of excess or unwanted tissue.● Preparing dental cavities for fillings.● Removal of benign tumors.● Sealing blood vessels.● Enabling the regeneration of nerves.● Expose wisdom teeth.● Teeth whitening.
Lasers are light, focused in a way so that the beam produced has high energy. This high-energy beam can be used very much like a stainless steel scalpel for cutting various tissues. The wavelength of the laser can also be adjusted depending on the type of tissue being treated. Different wavelengths are used when treating teeth, gums, and infections.
Usually when a cavity needs to be cleaned and filled the dentist will first scrape out the plaque with a tool called a dental hatcher. Next, a small electrical drill is used to widen the cavity and to prepare it for filling. A laser can replace both the hatcher and drill and prepare the tooth for the filling.
Infected and inflamed gum tissue is a different color from the healthy gum tissue. Because of the difference in color, the unwanted tissue absorbs light differently from healthy gums. Taking advantage of this principle the wavelength of the laser can be adjusted so that only the unhealthy tissue gets affected and the healthy tissue is left unharmed. During gum surgery, lasers can be used to remove infected tissue and also seal blood vessels. Certain wavelengths of the laser can make gum tissue sticky which causes it to start regenerating and healing. Oral nerves can also be regenerated in this way.
What are the advantages of using lasers in dentistry?
Lasers can seal blood vessels while removing infected tissue; this is why one of the main advantages of laser dentistry is a reduction in bleeding during and after a procedure. There is no need for stitches after laser dental surgery. Patients generally heal faster after such procedures as compared to more traditional methods. The discomfort and pain that comes from drilling a tooth can be eliminated by using lasers to treat cavities. Lasers can serve the dual purpose of killing an infection as well as removing infected tissue, eliminating the need for an extra step.
