Learn more about this product The Cavex Bite&White Aligner Whitening Pen is the first whitening solution engineered specifically for patients undergoing clear aligner treatment. Developed by Cavex Holland BV — a Dutch dental innovation company with decades of expertise — this pen lets you straighten and whiten simultaneously, turning your aligner wear time into a full smile transformation. At the heart of the pen is Cavex’s proprietary HPS (Hydrogen Peroxide Superior) technology: a water-based gel with 3% hydrogen peroxide delivering 6% effective whitening concentration. When the gel contacts teeth and saliva, hydrogen peroxide breaks down into oxygen and water, releasing free radicals that break the chemical bonds behind stubborn stains. The result is progressive, natural-looking whitening — without chair time, without custom trays, without fuss. The pen format makes application precise and effortless. Simply remove the cap, twist the base to dispense a small amount of gel, and apply directly to the tooth surfaces before inserting your aligners. Each 6ml pen contains enough gel for approximately 30 days of daily use. Wear for as little as 20 minutes or up to 2 hours — whatever fits your lifestyle. The gel is tooth-friendly, safe for sensitive teeth when used as directed, and also has an antibacterial effect that helps prevent plaque and biofilm buildup during aligner wear. Compatible with all clear aligner systems including Invisalign, Clear Correct, and any custom aligner. Stored at room temperature and designed for easy travel. If you experience sensitivity when switching to a new aligner tray, simply pause whitening for a day or two and resume when comfortable. Professional-grade whitening, now available to use at home — on your schedule.
