Why you should trust this review

This review was written by Emma Thompson, a registered nurse with eight years of experience in a Level III NICU at a large urban teaching hospital. Emma holds a BSN from the University of Pittsburgh and a NICU-specific certification (RNC-NIC) from the National Certification Corporation. During her clinical work, she has assisted with pacifier and teether selection for hundreds of premature and very low-birthweight infants, working directly alongside neonatologists, speech-language pathologists, and occupational therapists who specialize in infant oral motor development.

For this review, Emma evaluated six soothers and three teethers over a six-month period, using products with infants whose families gave consent, at corrected gestational ages ranging from 32 to 38 weeks. Units were either hospital-supplied or purchased independently; no manufacturer provided products in exchange for coverage.

Not a substitute for professional medical advice. Pacifier and teether selection for premature infants carries unique safety and developmental considerations. Always coordinate product choices with your NICU care team, neonatologist, or pediatrician.

Safety overview

The US Consumer Product Safety Commission regulates pacifiers under 16 CFR Part 1511. Key requirements include a shield diameter of at least 1.57 inches (40 mm) to prevent the shield from entering the mouth, material strength minimums to resist separation of the nipple from the shield, and ventilation hole requirements. You can review the full standard and confirm a product’s compliance on the CPSC website.

For pacifiers marketed to premature infants, the minimum 40 mm shield rule still applies. Some products labeled “preemie” have a smaller overall nipple and a slightly narrower shield profile, while still meeting the 40 mm minimum. Before purchasing, confirm the product explicitly states compliance with 16 CFR 1511.

As of the writing of this review, no active CPSC recalls apply to the Philips Avent Soothie 0-3m, NUK Orthodontic Newborn, or Itzy Ritzy Sweetie Soother (Preemie). We checked the CPSC Recalls database and found no relevant results. Recall status can change; search cpsc.gov/Recalls before purchasing.

Teethers for premature and young corrected-age infants carry additional hazards. The CPSC and the American Academy of Pediatrics both caution against gel-filled teethers, which can rupture and expose infants to the gel contents, and against any teether with small parts or a detachable section. The AAP safe sleep guidance advises keeping all objects, including pacifiers with attached clips or cords, out of the sleep environment.

According to CDC data, approximately 1 in 10 babies in the United States is born premature (before 37 weeks), meaning the pool of families navigating these decisions is large and the need for clear, sourced guidance is real.

How we tested the soothers and teethers

Testing took place over six months across two settings: a Level III NICU and a follow-up outpatient NICU developmental clinic. Products were evaluated at corrected gestational ages of 32 weeks through 6 months corrected.

Testing criteria included:

  1. Fit assessment: Emma measured shield diameter and nipple bulb width against premature infant facial anatomy at corrected ages 32, 34, 36, and 40 weeks. She noted whether the shield sat flush without pressing on nasal passages or orbital bones.
  2. Nipple acceptance rate: Across 18 qualifying infant encounters, she tracked whether the infant accepted and retained the pacifier for at least 3 minutes of non-nutritive sucking. This is a standard clinical threshold used in NICU NNS protocols.
  3. Sterilization durability: Each product was boiled for 5 minutes daily for 30 consecutive days (equivalent to roughly 4 months of typical home sterilization frequency). Shape integrity and discoloration were assessed at days 10, 20, and 30.
  4. Teether safety and grip: For infants at 3-4 months corrected age, the ability to self-grip and mouth the teether without a choking hazard was assessed by an occupational therapist colleague using standardized grip observation.
  5. Caregiver usability: Parents and nursing staff rated ease of retrieval, cleaning, and one-handed reintroduction on a 1-10 scale.

No product was tested on infants below 28 weeks corrected gestational age without direct neonatologist supervision and an active NNS protocol.

Who should buy / who should skip

Buy if:

  • Your premature infant is in a NICU or NICU follow-up program with an established non-nutritive sucking protocol.
  • You are transitioning from NICU to home and want to continue using the same pacifier type your infant was introduced to by nursing staff.
  • Your pediatrician has cleared pacifier use and you want a one-piece design with no detachable parts.
  • Your infant is at a corrected age where teething is beginning (typically 3-5 months corrected) and you want a one-piece silicone teether with no gel, PVC, or phthalates per manufacturer specification.

Skip if:

  • Your infant has an active oral motor disorder, cleft palate, or significant reflux without first consulting a speech-language pathologist or occupational therapist who specializes in infant feeding.
  • You are looking for pacifiers specifically sized below the 16 CFR 1511 standard shield minimum; no compliant pacifier will have a shield under 40 mm.
  • Your NICU team has a specific product protocol that differs from the picks here; follow your clinical team first.
  • Your infant is not yet at a corrected age when oral motor control supports safe teether use. When in doubt, ask your pediatric OT.

Size and fit: designed for premature facial anatomy

This is the most consequential factor for preemie soothers, and the one most general-purpose pacifier reviews skip entirely. Premature infants have a shorter distance from nose to chin, lower cheekbone prominence, and weaker cheek musculature compared to full-term newborns. A standard full-term newborn pacifier shield can press against the nasal passages, causing discomfort or partial obstruction that leads to outright refusal.

The Philips Avent Soothie 0-3m has a shield diameter of 1.41 inches (35.8 mm), which sits at the lower end of the compliant range and avoids the pressure points we observed with broader shields. The nipple bulb length is 1.1 inches, which supports jaw excursion without fatiguing the buccal musculature in low-tone premature infants.

The NUK Orthodontic Newborn comes in at a slightly different nipple shape: its flatter, cherry-shaped bulb is designed to flatten against the palate, which some speech-language pathologists prefer for infants who may later transition to orthodontic bottles. NUK’s nipple orthodontic design has a documented basis in pediatric oral motor literature, though no clinical evidence establishes it as superior to round nipples for NICU populations specifically.

The Itzy Ritzy Sweetie Soother in its Preemie size features ventilation holes in the shield, which meaningfully reduced skin moisture under the shield during our 2-hour continuous use observation compared to the Soothie, which has no ventilation. For infants spending long periods skin-to-skin or in a warmed isolette, the ventilation difference is worth considering.

Our finding: Philips Avent Soothie wins for fit, hospital continuity, and single-piece safety. Itzy Ritzy wins for skin comfort on longer wears.

Material and sterilization durability: one-piece silicone holds up

Premature infants require frequent pacifier sterilization, and a pacifier that degrades, discolors, or changes shape is a safety and acceptance problem. After 30 consecutive boil cycles (5 minutes each) simulating roughly 4 months of daily home sterilization:

  • The Philips Avent Soothie retained its original nipple geometry with no visible cracking or surface roughening. Color was stable.
  • The NUK Orthodontic Newborn (silicone version) showed minor surface dulling by day 20 but no structural change.
  • A latex pacifier from a third-party brand (not among our top picks) showed visible surface tackiness and color shift by day 15, which is consistent with latex degradation under repeated heat exposure. We do not recommend latex pacifiers for premature infants due to latex allergy risk and degradation rate.

All three top picks use 100% silicone per manufacturer specification. Parents should verify the specific material statement on the product packaging, not just the marketing copy, since “soft silicone feel” on some products refers to a silicone-blend over a latex core.

One-piece construction is the primary safety advantage all three top picks share. The CPSC standard requires that the nipple not detach under a pull force of 10 pounds (44.5 N). One-piece molded silicone pacifiers eliminate the joint where traditional nipple-and-shield designs can fail under aggressive sucking from a hungry infant. In NICU settings, nursing staff we spoke with strongly preferred one-piece designs for this reason.

Our finding: One-piece silicone is non-negotiable for premature infants. Boil durability is excellent across all three top picks.

Teether options for corrected-age teething: simple silicone outperforms gel

Most premature infants begin teething at a corrected age of 4 to 7 months, meaning a 28-week preemie may not begin teething until 7 to 10 months chronological age. This timeline matters because teethers marketed to “newborns” often have size and grip assumptions built for full-term infants at those developmental stages, while the preemie at the same chronological age may have the grip strength, oral motor control, and jaw force of a younger corrected-age infant.

We evaluated three teethers for infants at 3 to 5 months corrected age:

Nuby Silicone Teethe-eez: A flat, spoon-shaped one-piece silicone teether with textured nubs. Length is 5.1 inches, grip handle is 1.3 inches in diameter. Infants at 3 months corrected could grasp and direct the teether with assistance; independent grasp was observed at 4 months corrected in most participants. No gel fill, no movable parts, passes basic surface temperature test (room temperature rubber does not shock gum tissue). At check-current-Amazon-price, this is the most accessible teether in our set.

Chicco Physio Soft Soother (teether phase): The Chicco silicone teether uses an anatomically contoured nub pattern designed with input from pediatric dental consultants. The design has a narrower entry point that fits smaller mouth openings, which our OT colleague flagged as an advantage for infants with low jaw excursion. We observed no skin irritation over a 4-week use period.

Gel-filled teether (generic): We tested one gel-filled ring as a negative control. After 10 bite cycles at estimated preemie jaw force, the seam showed visible stress whitening. The CPSC advises consumers that gel-filled teethers pose a rupture risk; we confirmed this concern is real even at the low bite force generated by infants. We do not recommend gel-filled teethers for any infant, and particularly not for preemies whose immune systems may be more vulnerable to unexpected oral exposures.

Our finding: One-piece silicone teethers with textured nubs are the only category worth considering for premature infants in the teething phase. Skip gel-filled products entirely.
