SX Pro™ Physiological Teat, The Teat Revolution! The definitive step towards a more natural bottle feeding, designed to respect the development of the baby's oral cavity: The SX Pro™ Physiological Teat ensures that the tongue remains in the same physiological/natural position as when the baby is breastfeeding. Created taking into account the oral and dental characteristics of babies, whose maxilla and mandible are fully developing. Complying with the most advanced professional recommendations to avoid interfering with the development of the oral cavity. Endorsed by the Spanish Society of Pediatric Dentistry. Physiological Shape. Flat and symmetrical: This is the shape most recommended by pediatric dentists. It leaves more space for the tongue in the oral cavity so that sucking is as natural as possible². Longer neck² -> 20mm: Reaches the junction of the hard and soft palates, as recommended by scientific studies³ to achieve a more natural suction. Neck centered with respect to the base -> 90°: The most comfortable for the baby who picks up the bottle alone. Anti-colic valve: Allows pressure to be balanced between the outside and inside of the bottle. Slightly bulging concave base: Ensures that the mouth, tongue, and jaw muscles are positioned correctly. It allows greater adaptability, since a newborn baby will rest their lips in the center of the base, while an older baby with a larger mouth will be able to place their lips almost on the outer edge, taking the entire teat into their mouth. It allows the tip of the teat to reach more or less behind the palate, depending on the baby Growing up. Ultra-soft, fine silicone with a sandblasted finish, imitates the texture and consistency of the mother's nipple, achieving: Maximum warmth. Super flexible movement. Maximum adaptation to the shape of the palate
