Ultra Dex low-abrasion toothpaste is a clinically proven formula that was created by a professor of dentistry for dental professionals & is use & recommended by them. The intelligent i Q+ Active Oxi Technology within Ultra Dex works with your natural oral p H level to release the appropriate amount of active ingredients to meet the needs of your mouth. Ultra Dex low-abrasion toothpaste is clinically proven to whiten teeth within 14 days by gently oxidising organic stains to reveal the true brightness of your teeth. The toothpaste has a low RDA (relative dentin abrasivity) of 53 to help ensure it does not erode tooth enamel. The advanced technology is also clinically proven to prevent bad breath by eliminating, not simply masking, odour-causing volatile sulphur compounds (VSC) for all day fresh breath confidence. The anti-bacterial action kills both anaerobic & aerobic bacteria that, without the correct preventative measures, can cause gum problems, tooth decay & plaque. Bacteria cannot become resistant to Ultra Dex & regrowth is inhibited. Safe for daily use. Suitable for people with sensitive teeth. 100% free from harsh abrasives (RDA 53) & Sodium Lauryl Sulphate (SLS)
