Tooth-friendly Now you can choose a really good pacifier for your child! Denty FUTURA’s nipple is designed to help the tongue remain in the middle of the mouth placing even pressure on the molars (or back teeth) in both the upper and lower jaw, which prevents crossbite. The part on the nipple where your baby’s teeth meet is broad and thin, which decreases the risk of developing an open bite. This design spreads pressure evenly on the front teeth, which decreases the need for braces later in life.
