Curaprox Baby Soother Size 2

The Curaprox Baby Soother Size 2 is the largest soother in Curaprox's biofunctional range, designed for children aged 2.5 years and older who are still using a soother. Developed by Swiss oral care brand Curaprox with Austrian orthodontist Dr Herbert Pick, it uses the same flat, broad and flexible silicone teat as sizes 0 and 1, scaled up for an older child's mouth. It comes with its own protective box and is certified to the European soother safety standard EN 1400.

By around two and a half, most children have all their milk teeth, and a long-running soother habit is more likely to influence how those teeth and the jaw line up. Size 2 is designed for children who still need a soother at this stage, using a shape intended to work with natural tongue and jaw function rather than against it.

Why the shape is different

A round or cherry-shaped teat sits low in the mouth and pushes the tongue down, away from its natural position against the roof of the mouth. With long-term use, that can contribute to an open bite (where the front teeth don't meet) and a narrowing of the upper jaw that can lead to a crossbite.

The Curaprox size 2 teat is built differently:

• Flat, tapered shape: In the published Basel case series, the size 2 teat is described as a triangular shape that tapers into a shaft, around 25 mm wide at its widest point and 23 mm long, so it takes up far less vertical space than a round bulb.
• Side wings with recesses: Its 4 mm-thick side wings have small recesses at the edges that can sit alongside the teeth in children with a narrow upper jaw.
• Soft central semicircle: A raised 10 mm semicircle in the centre is pressed by the tongue during sucking. The researchers describe this as creating sideways (transverse) pressure on the upper jaw, which may help counter narrowing.
• Lip plate set away from the jaw: The shield sits away from the lower jaw, giving the lip muscles room to work without pushing the lower jaw backwards.
• Active, not passive: It stays in place only while your child is actively sucking.

What the research shows

• A small clinical case series from the University Centre for Dental Medicine Basel, using size 2: 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, and switched them to the Curaprox size 2 soother, used at least at night or to fall asleep. In one four-year-old, a 7 mm open bite reduced to 5 mm after six weeks, 2 mm after five months and a normal bite after nine months, alongside a change from an infantile to an adult swallowing pattern. In a two-and-a-half-year-old, the open bite closed within three months. The children accepted the soother well, and weaning off it afterwards wasn't a problem. The authors describe the results as encouraging, but stress that with only three cases they can't be confirmed without a larger study.
• 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, an engineering simulation, to compare how different soother shapes press against modelled palates. Curaprox reports 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 children.

In short: size 2 is the soother size these early findings relate to most directly, and the results are promising, but the evidence is still limited to a handful of cases. It is not a replacement for assessment and treatment by a dentist or orthodontist.

Who size 2 is for

Curaprox recommends size 2 for children aged 2.5 years and older who are still using a soother, who need a larger soother, or who show early minor irregularities in their bite, with professional assessment recommended. The Basel researchers note that, ideally, sucking habits stop once all the milk teeth are through, at around two and a half, so size 2 is best seen as a better option for children who aren't ready to give up their soother yet.

How to use

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

Every day: Clean before each use. Inspect before every use by gently pulling the teat in all directions, and throw it away at the first sign of damage or weakness. Older children with a full set of milk teeth can bite through a teat, so check it carefully. Store in the protective box when not in use, but don't leave it 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 2 is a great option for parents who:

• Have a child aged 2.5 years or older who still relies on a soother, especially to fall asleep
• Want to swap a conventional round dummy for a shape designed around jaw and tongue function
• Have been advised by a dentist or orthodontist to try a biofunctional soother
• Are moving up from Curaprox size 1

It may not be the best fit if you:

• Have a child under 2.5; sizes 0 and 1 are designed for younger children
• Are ready to wean your child off a soother altogether
• Are looking for a treatment for an existing bite problem without professional input

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 child when using a soother. If you've noticed changes in your child's bite, such as front teeth that don't meet, book a dental check-up; the soother can be part of the conversation, but your dentist should guide any treatment.

Pandylane Pro Tip: For older children, limiting the soother to sleep time, as in the Basel cases, is a gentle middle ground. Keeping it in its box by the bed makes it part of the bedtime routine rather than something they reach for all day, which also makes weaning easier later on.
