The Parent's Guide to Pacifier Shapes, Oral Health & Why BIBS Gets It Right

If you have ever stood in the pacifier aisle staring at round nipples, flat nipples, symmetrical nipples, and orthodontic shapes, wondering what on earth the difference actually is, you are not alone. Pacifier shape is one of the most common questions new parents ask, and it comes loaded with well-meaning advice, contradictory opinions, and a fair amount of unnecessary worry.

The good news is that choosing the right pacifier does not have to be complicated. BIBS has been making pacifiers in Denmark since 1978, and their thoughtfully designed lineup covers the full range of nipple shapes so parents can find what works best for their baby. Let us break down what pacifier shape actually means for your baby's oral health and how the BIBS lineup fits into that picture.

TL;DR

• Pacifier shape — round, flat, symmetrical, or anatomical — affects how the nipple interacts with your baby's palate, tongue, and developing jaw.
• Round nipples like those used by BIBS most closely mimic the shape of a breast during active nursing, making them a natural choice for breastfeeding families.
• Flat, symmetrical, and anatomical nipples are each designed to sit differently in the mouth, and some feeding specialists recommend them for babies with specific oral motor needs.
• No pacifier shape has been proven definitively superior for all babies. What matters most is finding the shape your baby accepts, using it consistently within recommended age guidelines, and weaning at the right time.
• Every BIBS pacifier is made with baby-safe materials — either natural rubber latex or medical-grade silicone — and is free from BPA, BPS, and harmful chemicals.
• Not sure which shape your baby prefers? The BIBS Try-it Collection lets you sample multiple styles before committing.

Why Pacifier Shape Matters

A pacifier does a lot more than soothe. In the early months, non-nutritive sucking plays an important role in self-regulation, stress relief, and sleep. It also has a well-documented association with reduced risk of SIDS when used at sleep time. But the shape of the nipple your baby sucks on repeatedly, across dozens of sessions every day, can influence how the mouth develops over time, particularly if pacifier use continues well into toddlerhood.

The key structures at play are the palate (the roof of the mouth), the jaw, and the tongue. In infancy, these structures are soft and highly responsive to repeated pressure and positioning. A nipple that sits in the mouth incorrectly or exerts pressure in the wrong place for an extended period can affect the shape of the palate or the alignment of emerging teeth. This is why pediatric dentists generally recommend weaning from pacifiers by age two, and ideally by twelve to eighteen months, to minimize any long-term oral effects.

The shape of the nipple determines where it sits in the mouth, how the tongue interacts with it, and what kind of pressure it places on the palate. This is what the round vs. flat vs. symmetrical vs. anatomical debate is really about.

Round Nipple Pacifiers

Round nipples are the classic pacifier shape, and they are what most people picture when they think of a soother. The nipple is round in cross-section, filling the mouth fully when baby sucks.

The round nipple shape is designed to mimic a mother's nipple during active breastfeeding, when breast tissue is drawn deeply into the baby's mouth and forms a rounded shape against the palate. For this reason, many breastfeeding advocates and lactation consultants prefer round nipple pacifiers for nursing babies, as the sucking mechanics are most similar to what the baby does at the breast.

From an oral health standpoint, round nipples sit centrally in the mouth and encourage the tongue to cup naturally around the nipple, which is close to the natural sucking position. Any concerns with pacifier use are more relevant for extended use past the recommended age window rather than for the round shape itself.

BIBS's signature round nipple is the shape the brand was founded on in 1978, and it remains the core of their pacifier lineup today. The gentle, cherry-shaped round nipple is designed to sit naturally in the baby's mouth and encourage a comfortable, relaxed sucking position.

Flat and Symmetrical Nipple Pacifiers

Flat or symmetrical nipple pacifiers feature a nipple that is flattened on one or both sides rather than fully round. These shapes are often described as "orthodontic" because they were developed with the intention of placing less upward pressure on the palate and allowing the tongue to rest in a lower, flatter position during sucking.

Symmetrical nipples are the same on both sides, meaning the pacifier can be inserted either way up. Flat nipples have a distinct top and bottom, with the flattened portion designed to face downward toward the tongue.

Some speech-language pathologists and feeding specialists recommend flat or symmetrical pacifiers for babies who have specific oral motor concerns, such as low tongue tone or a tendency to thrust the tongue forward. For most babies, however, the choice between round and flat comes down to preference, and a baby's own acceptance is often the most practical guide.

Anatomical Nipple Pacifiers

Anatomical nipples are asymmetrical by design, making them their own distinct shape category separate from both round and flat. The nipple has a flattened underside and a curved, domed top, shaped to follow the natural contours of the baby's mouth at rest. The flat bottom sits along the tongue, while the domed upper surface presses gently against the palate, mimicking the shape the breast takes inside the mouth during a deep latch.

Because the top and bottom of an anatomical nipple are different, these pacifiers have a correct orientation and should be inserted with the flat side facing down toward the tongue. This makes them slightly less grab-and-go than symmetrical options, but many parents find their baby takes to the shape quickly and settles well with it.

Anatomical pacifiers are sometimes recommended for babies who are transitioning between breast and bottle, or for those who have a tendency to push a round nipple out of position. The shape encourages the tongue to rest in a naturally low, forward position, which some feeding therapists consider supportive for oral motor development.

BIBS offers anatomical nipple options across two of their collections. The Natural Rubber Pacifier Combo comes in round, anatomical, and symmetrical variants in the same pack, making it easy to try the anatomical shape alongside the classic round without committing to a full set. The Silicone Pacifier Infinity also comes in an anatomical version in medical-grade silicone, a great option for families who want the anatomical shape in a hypoallergenic, easy-to-sterilize material.

Beyond shape, the material of the nipple also affects how a pacifier feels and functions in the mouth.

Natural rubber latex is soft, flexible, and warm to the touch, which many babies find more appealing and breast-like. It has a natural give and compression, so it moves slightly with the baby's sucking motion. BIBS sources its natural rubber latex from sustainably tapped rubber trees, and it is free from BPA and harmful chemicals. Parents with a family history of latex allergy should consult their pediatrician before choosing a latex pacifier.

Medical-grade silicone is firmer, odourless, and easier to sterilize. It holds its shape well over time and does not degrade as quickly as latex. Silicone is hypoallergenic and a good choice for babies with sensitive skin or families with latex concerns.

BIBS offers both materials across their range, so parents can choose based on their baby's preference and any allergy considerations.

The BIBS Pacifier Lineup

BIBS offers several pacifier collections, all built around their signature round nipple shape in both natural rubber latex and medical-grade silicone.

The Natural Rubber Colour Pacifier is the BIBS classic, the original round latex pacifier that has been soothing babies since 1978. Available in a wide range of colours in sizes 0–6 months and 6–18 months, this is the pacifier most parents picture when they think of BIBS. The soft, cherry-shaped natural rubber nipple is designed to feel as close to the breast as possible, and the lightweight shield with ventilation holes keeps it comfortable against baby's face. It comes in a 2-pack so you always have a spare.

The De Lux Silicone Natural Pacifier takes the same beloved round shape and renders it in one seamless piece of medical-grade silicone. Because it is moulded as a single piece with no joins, it is extremely easy to clean and very hygienic. A great choice for families who prefer silicone or need to avoid latex.

The Boheme Natural Rubber Pacifier combines the classic BIBS round latex nipple with a beautifully patterned shield. The nipple itself is identical to the Colour Pacifier, making it just as gentle and breast-like in feel, but the Boheme brings a more elevated aesthetic for parents who love a curated look. Available in coordinated colour duos in a 2-pack.

The Studio Collection Natural Rubber Pacifier features the same trusted round latex nipple on a subtly patterned shield with a refined, modern design. Available in a 2-pack in sizes 1 (0–6 months) and 2 (6–18 months), the Studio line is for parents who want the function of the classic BIBS pacifier with a more design-forward look.

The Liberty Natural Rubber Pacifier is a collaboration between BIBS and the iconic Liberty London print house. The classic round latex nipple is paired with BIBS's signature shield featuring Liberty's beloved floral prints. The nipple shape and material are identical to the rest of the BIBS latex range, making this a purely aesthetic upgrade for parents who love Liberty's signature aesthetic.

Not sure which BIBS pacifier your baby will prefer? The Try-it Pacifier Collection is the perfect starting point. It includes one of each BIBS pacifier type so you can let your baby tell you what they like before committing to more. It also makes a thoughtful baby shower gift for parents who are just getting started.

If you specifically want to explore anatomical and symmetrical shapes alongside the classic round, the Natural Rubber Pacifier Combo lets you compare all three nipple types in the same colour combination — an easy way to discover what your baby prefers without buying multiple individual packs.

Tips for Healthy Pacifier Use

Whatever shape or material you choose, these guidelines will help support your baby's oral health over time:

Choose the right size. BIBS pacifiers come in age-appropriate sizes. Using a nipple that is too large for your baby's mouth can place unnecessary pressure on the palate, while one that is too small may not satisfy baby's sucking reflex. Move up a size as your baby grows.

Wean by age two. Pediatric dentists generally recommend phasing out pacifier use by age two to avoid long-term effects on tooth alignment and palate shape. Beginning to reduce use around twelve months makes the transition easier.

Never modify the nipple. Do not cut or alter the nipple. A modified nipple can become a choking hazard and will no longer function as designed.

Inspect regularly. Natural rubber latex pacifiers should be checked before every use by pulling the nipple firmly in all directions. If you see any cracks, tears, or stickiness, replace it immediately. Latex pacifiers have a shorter lifespan than silicone.

Do not dip in sugar or honey. Honey should never be given to babies under twelve months due to the risk of botulism, and coating a pacifier in anything sweet is harmful to developing teeth and overall health.

Keep it clean. Sterilize new pacifiers before first use. After that, clean with warm soapy water or use a sterilizer. Avoid cleaning a dropped pacifier in your own mouth, as this can transfer bacteria associated with early tooth decay.

Final Thoughts

Pacifier shape is genuinely worth thinking about, but it is not something to lose sleep over. The most important things are choosing a pacifier made from safe materials, picking a shape your baby will actually accept, using it within the recommended age guidelines, and weaning at the right time. BIBS makes all of this straightforward with a range built on their trusted round nipple, in both natural rubber latex and silicone, across beautifully designed collections that grow with your baby from the newborn stage onward.
