Squigle - Tooth Builder Sensitive Toothpaste - 4 oz. Squigle Tooth Builder Sensitive Toothpaste is hypoallergenic toothpaste to prevent sensitive teeth, fluoride free. Tooth Builder uses calcite nano-particles to seal off the open tubules in your teeth, eliminating the primary cause of tooth sensitivity. Tooth Builder has a patented super-mild detergent, instead of using sodium lauryl sulfate (SLS), cocamidopropyl betaine (CPB) or irritating detergents found in other toothpastes. Tooth Builder's detergent is so mild it is used in artificial tears. Tooth Builder has no harsh abrasives, no irritating tartar control agents and no bleaches.Conventional tooth sensitivity toothpastes contain potassium nitrate, which works as a local anaesthetic, calming sensitive tooth nerves. This kind of treatment is not as effective as stopping tooth sensitivity by eliminating the cause - by sealing the open dentinal tubules, the way Tooth Builder does. Tooth Builder has a massive 36% natural Xylitol - far more than any other toothpaste. Xylitol has a powerful antibacterial action, particularly inhibiting the growth of Strep Mutans, the main bacteria responsible for cavities and other oral complaints. Xylitol reduces plaque, plaque acids and tartar.Tooth Builder Toothpaste fights or prevents: Tooth Sensitivity Mouth ulcers (canker sores, recurrent aphthous stomatitis) Plaque, tartar, cavities Bad breath (simple halitosis) Gum disease (periodontal disease) Perioral dermatitis Chapped Lips Surface stain Fights Decay 5 Ways: 36% Xylitol - Profoundly inhibits the growth of bacteria Soluble Calcium - Replaces calcium lost to decay and food acids.
