The new Supersmile ultimate whitening system combines our best selling professional whitening system with our professional activating rods for dramatic whitening results along with health benefits to your teeth and gums including protection against cavities and re-mineralizing of the enamel. The ultimate whitening System is not your average at-home whitening kit as it whitens teeth several shades while simultaneously strengthening teeth and killing the germs that cause bad breath. It's even great for people with sensitive teeth since Supersmile products are formulated without harsh abrasive that can cause tooth sensitivity.
