After successfully brightening smiles overseas, Magic Smile came stateside to perform teeth-whitening treatments with its patented multistrength formula?available in eight strengths to match varying levels of sensitivity. Technicians prop jaws open with a comfortable mouth opener before painting the formula directly onto teeth, negating the need for messy trays. A special laser LED light then beams down on teeth to activate the stain-removing process. After treatments, teeth appear up to six shades lighter and can retain their new hues for up to two years. Unlike reading sonnets to one's molars, the treatments do not significantly increase dental sensitivity.
