The countdown to reach your teeth’s whitest potential is on. The bright on Pro Whitening System brightens faster and lasts longer – up to 6 months. The secret is our 3-step system that breaks up stains, whitens up to 9 shades, and prevents new stains from forming. In the first step, ProActivate whitening accelerator toothpaste preps your teeth with a vigorous, deep cleaning that breaks up tough stains and removes plaque. It’s a bit grittier than regular toothpaste, yet safe for enamel and dentine. You’ll feel it working from the moment you start. Plus, each tube has enough paste for 2 full 1-week treatments, so there’s plenty left for when you whiten your teeth again in 6 months. Simply store it in a cool, dry place (frost-free) until you’re ready for another treatment. Directly after completing step 1, it’s time to brighten. ProBrighten premium teeth whitening gel, with exclusive Bright Boost formula and patented 20-LED accelerator light, gets your teeth up to 9 shades whiter in 1 week.* Specially formulated for sensitive teeth, it starts whitening after 1 use, and takes just 5 minutes, twice a day. Each pen holds about 4 applications, so if there’s gel left after 4 uses, SmileDirectClub recommends you keep using it. The final step protects and prolongs your whitening results. ProLong whitening extender gel is specially formulated to condition and protect your pearly whites and prolong your whitening results. The post-whitening extender gel works by smoothing your tooth’s surface to prevent food and beverage residue from sticking and re-staining, leaving your teeth with a bright, shining luster. One pen lasts an entire treatment. The Pro Whitening System comes with 2. Store the extra in a cool, dry place (frost-free), away from sunlight, for a second treatment in 6 months. *Average results after 1 week when used as directed. Results may vary.
