The NUK Range The unique NUK orthodontic shape was developed over 50 years ago after intensive research by two German orthodontists, Professor Dr. W Balters & Dr. med. dent. A Muller. Their research found that prolonged use of conventional round teats & soothers could cause oral abnormalities like open bite. They therefore decided to develop a teat that is based on the shape of a mother's nipple during breast-feeding. By closely mimicking the sucking action of breast-feeding, NUK teats & soothers encourage the correct oral development for your baby. Because of our experience & expertise, NUK teats are used in many maternity & neonatal wards throughout the UK. In fact, NUK is currently used in over 200 hospitals, including Great Ormond Street, Alder Hey & Birmingham Children's Hospital. The NUK orthodontic teat is the only teat approved by the British Dental Health Foundation.
