A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The term “laser” originated as an acronym for Light Amplification by Stimulated Emission of Radiation. Lasers differ from other sources of light because they emit light coherently. Its spatial coherence allows a laser to be focused to a tight spot, and this enables applications like laser cutting and laser lithography. Its spatial coherence also keeps a laser beam collimated over long distances, and this enables laser pointers to work. Laser also have high temporal coherence which allows them to have a very narrow spectrum, i.e., they only emit a single color of light. Their temporal coherence also allows them to emit pulses of light that only last a femtosecond.
Lasers have many important applications. They are used in common consumer devices such as DVD players, laser printers, and barcode scanners. They are used in medicine for laser surgery and various skin treatments, and in industry for cutting and welding materials. They are used in military and law enforcement devices for marking targets and measuring range and speed. Laser lighting displays use laser light as an entertainment medium. Lasers also have many important applications in scientific research. Source: Wikipedia.
By visiting a laser dentist, you’ll have the opportunity to experience a new and exciting technology. Here, you will have some basic information and perhaps reduce any of your concerns.
Dental laser is a tools that is used by dentist to do his work. Some lasers are used for surgery, some to cure restorative materials and enhance tooth bleaching, and others to remove tooth structure for elimination of disease and restoration – different lasers for different procedures. All lasers require eye protection. Safety glasses with special lenses will be provided. Family and guests in the dental operatory at the time of your laser treatment may also be asked to wear protective eyeglasses.
Lasers do not make whining sounds or other annoying noises. You may experience the sound of a rush of air, since air suction is often used to keep the area cool and cleaner. You should be able to relax and be comfortable while the dental laser is in use.
Depending on your treatment needs, your dentist may use the laser for a long period of time or possibly only for brief moments. However, even those procedures that require only a short period of laser usage benefit from the advantages of laser therapy. With laser surgery, there is a reduced need for local anesthesia, bleeding is minimized, swelling is controlled, and there is usually little, if any, postoperative discomfort. Laser energy enhances the effect of tooth bleaching agents for a faster and more effective result. Natural looking restorative materials for teeth are more quickly cured to greater hardness. Lasers that remove tooth decay are fast and seldom require anesthesia.
Dental lasers are used for a variety of treatment procedures. Your dentist knows which types of patient care are more patient friendly with a laser than with alternative traditional methods. The dentists using lasers have devoted training time and expense to be able to bring you the many advantages of this exciting new technology.
