Curaprox Baby Soother All Age Soother Size 0

The Curaprox Baby Soother Size 0 is a silicone soother with an unusually flat, broad and flexible teat, developed by Swiss oral care brand Curaprox with Austrian orthodontist Dr Herbert Pick. Instead of the rounded, bulb-shaped teat found on most dummies, it uses a thin, wing-shaped sucking part designed to leave room for your baby's tongue and to spread sucking pressure across the roof of the mouth in a different way. It's suitable from birth, comes with its own protective box, and is certified to the European soother safety standard EN 1400.

Curaprox calls the design "biofunctional", meaning it's intended to work with your baby's natural sucking, tongue and swallowing movements rather than simply filling the mouth. Below, we explain how the shape works, what the research does and doesn't show, and how to use it well.

Why the shape is different

In the first months of life, a baby's jaw, palate and tongue are still very adaptable, and how they're used during sucking influences how they grow. Most conventional soothers have a round or cherry-shaped teat. In the mouth, that bulk can push the tongue down and away from its natural resting position against the roof of the mouth, and concentrate pressure on the front of the palate.

The Curaprox teat takes a different approach:

• Flat and thin: The sucking part is flat rather than round, so it takes up less space and leaves room for the tongue to rest and move naturally.
• Broad side wings: Wing-shaped edges are designed to direct sucking pressure towards the sides of the upper jaw, rather than mainly to the front and centre of the palate.
• Soft, flexible centre: A soft central section is pressed by the tongue during sucking, which Curaprox says helps encourage natural tongue movement similar to breastfeeding.
• Active, not passive: The soother is designed to stay in place only while your baby is actively sucking. When they stop sucking, it isn't held in the mouth, so it doesn't sit there passively for long periods.

What the research shows

We think it's important to be clear about the evidence behind any product making claims about development, so here's exactly what has been published:

• A 2025 computer-modelling study from the University of Basel: Researchers (Maintz, Nalabothu, Thieringer and Verna, published in Head & Face Medicine) used finite element analysis, a type of engineering simulation, to compare how different soother shapes press against models of a newborn's and a six-month-old's palate. Curaprox reports that the study found its design directs pressure more towards the sides of the palate, rather than mainly to the front. This is a simulation, not a study on babies, but it supports the design principle behind the shape.
• A small clinical case series from the University Centre for Dental Medicine Basel: Paediatric and orthodontic specialists (Filippi, Filippi and Verna, first published in the Swiss Dental Journal in 2015) followed three children aged two to five who had open bites linked to bottle or dummy habits. After switching to the Curaprox size 1 and 2 soothers, the open bites closed or reduced over three months to two years, with improvements in crossbite and swallowing pattern. The authors describe the results as encouraging, but note that with only three cases, they can't yet be confirmed without a larger study. These children used the larger sizes, not size 0.
• Design recognition: The Curaprox Baby soother won a Red Dot design award in 2016.

In short: the shape is thoughtfully designed and the early findings are promising, but there isn't yet large-scale clinical evidence. It's a considered choice if you plan to use a soother, rather than a guarantee against future orthodontic issues, which depend on many factors including how long and how often a soother is used.

Size 0: from birth

Size 0 is Curaprox's everyday soother and is suitable from birth. Curaprox notes that many children stop using a soother around their first birthday; others continue with size 0, or move to size 1 (1 to 2.5 years). Sizes 1 and 2 are larger and are aimed at children with an ongoing sucking habit or early minor bite irregularities, ideally with advice from a dentist or orthodontist.

How to use

Before first use: Place the soother in boiling water for five minutes. Let it cool completely, then squeeze out any water left inside the teat and allow it to dry fully before use.

Every day: Clean the soother before each use. Inspect it before every use by gently pulling the teat in all directions, and throw it away at the first sign of damage or weakness. Store it in the protective box when not in use, but don't leave it sitting in the box for long periods, and keep it away from heat and direct sunlight.

Attaching it: Only use soother holders tested to EN 12586. Never attach ribbons, cords or strings.

Best For

The Curaprox Baby Soother Size 0 is a great option for parents who:

• Plan to offer a soother and want one designed with jaw, palate and tongue development in mind
• Prefer a soft, silicone teat that's suitable from birth
• Like the idea of a soother that's only held in place while baby is actively sucking
• Want a protective box for hygienic storage on the go

It may not be the best fit if you:

• Have a baby who prefers a rounder, more conventional teat; some babies take time to adjust to the flat shape, and some won't accept it
• Want a soother that stays in the mouth while baby sleeps without sucking
• Are looking for a treatment for an existing bite problem; speak to a dentist or orthodontist first

Good to Know

Curaprox describes the soother as made from skin-friendly silicone, free from harmful substances, and certified to EN 1400 safety standards. Always supervise your baby when using a soother. If you're breastfeeding, many health professionals recommend waiting until feeding is well established before introducing a soother. Soother use and its effect on teeth varies from child to child, so check in with your dentist or clinic sister if you have any concerns about your child's bite or oral development.

Pandylane Pro Tip: The flat shape can feel unfamiliar to babies who've used a round teat before. Offer it when your baby is calm and already sucking, rather than mid-cry, and give them a few tries over several days before deciding it isn't for them.
