Patients have reported reddening of the skin, which lasted from one to four months. Consumers should bear in mind that skin abrasion, whether achieved by lasers, chemicals or abrasive materials, means removing one or more layers of skin, which can be painful and could cause redness, swelling or scarring, depending on how each person heals. People considering this procedure should consult a dermatologist or the manufacturer to determine whether or not they would be good candidates. Be sure to ask your dermatologist for a copy of the patient labeling for the specific laser device used to understand the risks. Several manufacturers have received clearance for argon and carbon dioxide lasers to activate tooth-bleaching solutions and to treat gum disease.
Several lasers have clearance for hard tissue use on teeth.
Studies conducted by the manufacturers showed that the laser is as safe and effective as a high-speed drill for removing dental decay and preparing a cavity for a filling. The manufacturer's study indicated that fewer patients needed anesthetic for pain. Any inquiries regarding this method of cavity treatment should be directed to your dentist, who can provide you with patient labeling including risks for the specific laser. This may include removing tumors, cataracts, or proliferating blood vessels common to diabetic retinopathy. The laser is used to reshape the cornea and focus images correctly on the retina.
