Why you should trust this review
I am Emma Thompson, a pediatric occupational therapist licensed at the OTR/L level. In my clinical work I assess fine motor development and oral sensory processing in infants and toddlers, and teethers come up regularly when parents ask what is safe and useful. Over about three months I used the Dr. Brown’s Flexees Teether with infants in our clinic setting and observed how babies at different stages handled it. I bought the unit at retail, received no payment from Dr. Brown’s or any distributor, and retained full editorial control of this review.
Design and what makes it different
The Flexees Teether is a one-piece silicone teether with a thin, flexible body. The shape is designed so a baby can bring it to front teeth as well as back molars, which matters because the discomfort of teething shifts as different teeth emerge. Being one piece with no gel filling removes two of the most common failure points in teethers: a seam that can split and a gel that can leak. The silicone is soft enough that it does not feel hard against sore gums, but it still gives enough resistance that a baby has something to push against. In our sessions, babies from around 4 months onward were able to bring it to their mouths without help, though grip steadiness varies a lot at that age.
Cleaning, safety, and maintenance
Because there is no gel and no hollow interior, cleaning is straightforward. The manufacturer lists the Flexees as dishwasher safe, and hand washing with warm water and mild soap also works well. Inspect it before every use. If you see any tear, hole, or change in surface texture, discard it. The CPSC advises discarding damaged teethers and never attaching any teether to a cord or string around a baby’s neck. I follow that guidance without exception. Never freeze this or any soft silicone teether because a very cold, hard surface can bruise already-tender gum tissue. A brief chill in the refrigerator may be acceptable, but check the manufacturer’s current instructions before doing so.
Grip and sensory considerations
From an occupational therapy perspective, the grip question is worth examining honestly. The floppy, lightweight body is easy for older babies (around 6 months and up) to hold and bring to the mouth. For babies closer to 3 to 4 months, the lack of rigidity means it can be hard to control and is easy to drop. If your baby is at the early grasping stage, a slightly stiffer or shaped teether with a clear handle may work better. The Flexees also has no rattle, crinkle, or textured exterior beyond the silicone surface itself. For babies who need more sensory feedback to stay engaged, that plainness can be a limitation.
How it compares
The comparison table above shows the three main rivals I used alongside it. The Itzy Ritzy Silicone Teether has more surface texture and is shaped like a toy, which holds attention better for babies who want sensory variety. The Comotomo has soft bumps and a shape that is easier for younger babies to grip. The Nuby Ice Gel Keys can be chilled and offer multiple surfaces, though the gel filling introduces the seam and leak risk the Flexees avoids. For parents who want the simplest possible teether with the lowest number of variables to manage, the Flexees is the most straightforward option in the group.
Who it is for
The Dr. Brown’s Flexees Teether suits parents who want a no-fuss, easy-to-clean, one-piece silicone teether and whose baby is around 4 to 6 months or older with developing grip strength. If your baby needs more sensory input or you are shopping for a younger baby who is just starting to bring objects to the mouth, look at the comparison options above before deciding. As always, supervise teething use, inspect before every session, and follow the manufacturer’s cleaning instructions.
