Every NUK nipple features the NUK Air System – a unique venting system – which helps reduce colic. The natural shaped nipple mimics Mom’s to help make baby's transition from breast to bottle a seamless one. This unique nipple also has the drinking hole specially located on the top side – not the tip like round nipples -- which allows the milk to mix more effectively with saliva and promote easier digestion. NUK Orthodontic Replacement Nipples are silicone, fit all NUK wide neck bottles and are available in sizes Slow Flow (0-6 months), Medium Flow (6-18 months) and Fast Flow (18+ months).

Orthodontic Nipple

NUK bottles feature orthodontic nipples that have a more advanced design than round nipples to promote healthy oral development.

Special Design Helps Reduce Colic

The NUK Air System vents the bottle, preventing vacuum build up – this allows baby to drink continuously, swallowing liquid instead of air.

Hourglass Shape

The hourglass shape encourages a proper latch to help limit the intake of air through the mouth.

Simulates & Supports Breastfeeding

NUK Orthodontic nipple’s asymmetrical shape mimics mom’s to simulate and support breastfeeding, easing transition from breast to bottle and back.

Drinking Hole Specially Located at the Top Side of the Nipple

The feeding hole of the NUK orthodontic nipple rests against the palate – versus the tip on round bottle nipples - to allow milk to mix with saliva, aiding better digestion.
