The GUM Technique Sensitive Care is the toothbrush that has been clinically designed to be gentle on sensitive gums and teeth, while removing dental plaque and cleaning without compromise. The Quad-Grip® handle has a unique design that helps you always hold the brush the way most dental professionals do–at 45 degrees. Whether you are left- or right-handed or brushing upper or lower teeth, the handle intuitively helps you form the 45-degree angle that is more effective at cleaning away the dental plaque from both gums and teeth. This makes sure you have the right dental “technique”, essential as sensitive gums and teeth are often caused by harmful brushing actions. The bristles are very fine in diameter and ultra-soft in texture to be extra gentle on sensitive teeth and gums. On the surface of the brush head, the tufts of bristles are formed with a unique raised-center, the Dome Trim® bristle design, that has been clinically proven to clean below the gumline where periodontal disease starts.* The outer row of bristles are angled to increase their reach and penetration between the teeth for improved cleaning and plaque removal.
