Previously, the FDA had granted marketing clearance to lasers for use in soft tissue surgery, composite resin curing and bleaching procedures. Back to Top of Page I've heard about laser whitening. Lasers, like other light sources, can be used to enhance the effectiveness of in-office peroxide bleaching agents. This technique may be safe, but the ADA has not seen published data on the safety and effectiveness of laser whitening. This creates an image on the radiograph.
Teeth appear lighter because fewer X-rays penetrate to reach the film.
Cavities and gum disease appear darker because of more X-ray penetration. The interpretation of these X-rays allows the dentist to safely and accurately detect hidden abnormalities. It is important to recognize that just as each patient is different from the next, so should the scheduling of X-ray exams be individualized for each patient. Your dentist will review your history, examine your mouth and then decide whether you need radiographs and what type. If you are a new patient, the dentist may recommend radiographs to determine the present status of the hidden areas of your mouth and to help analyze changes that may occur later.
