No artificial flavors. Gluten-free. Since 1970. Natural. Toothpaste for sensitive teeth. Clinically proven formula with arginine & calcium carbonate. Seals expose pathways to the nerve of rapid relief (For rapid relief, apply the product directly to the sensitive tooth with fingertip and gently massage for 1 minute) & long-lasting protection (Lasting sensitivity relief based on continuous use). Micro openings at the tooth surface are pathways to sensitive nerves. Arginine & calcium carbonate formula seals pathways to help seal-out pain. Unlike some sensitive toothpastes which just numb the pain, our formula with the amino acid arginine & calcium carbonate quickly seals the pathways that lead to sensitive tooth nerves providing rapid relief. With regular use, it builds a long-lasting protective barrier that acts like a seal against sensitivity. tomsofmaine.com.
