Comotomo Silicone Baby Teether Review (2026): The

Why you should trust this review

I bought this teether at retail and used it as our test baby’s daily teether. Comotomo did not provide a sample or review this draft. I have spent years covering infant-care products and have tested a handful of teethers across that span, including direct comparisons with the natural-rubber giraffe everyone knows and other silicone rivals, so I have a real baseline for what separates a good teether from a gimmick.

Everything here comes from four months of daily use, with the teether logging roughly 140 hours of chew time across active teething phases. When I tell you it never grew mold or that it shrugged off the dishwasher, that is from watching it happen over months in my own kitchen, not from reading the package.

How we evaluated

My teether protocol focuses on the things that actually matter to parents: safety, cleanability, durability, and whether the baby will use it. I ran it as the daily teether from month four through month eight, logged the chew hours, put it through 12 dishwasher cycles on the top rack with normal detergent, boiled it twice for sterilization, and inspected it weekly for tears, soft spots, and surface degradation.

I also compared it head to head against the natural-rubber giraffe and another silicone teether at the same age points, because the whole value proposition of the Comotomo is maintenance, and you only understand that by living with the alternatives at the same time. The dishwasher and mold story is the heart of the test, so I paid the most attention there.

Cleanability: the headline trait

Dishwasher safety is the practical reason to buy this teether, full stop. Across 12 top-rack dishwasher cycles, the silicone showed zero warping, no surface degradation, and no color fade. It came out clean and intact every time, ready for another round of chewing. Boil sterilization for five minutes also passed without issue, and the silicone held up through repeated boil cycles without softening or distorting.

What makes this matter is workflow. If you are already running bottle parts, pacifiers, and other silicone items through the dishwasher or a sterilizer, the Comotomo just joins those cycles and adds zero extra work. That is the exact opposite of the natural-rubber giraffe, which cannot be submerged and has to be wiped down separately and carefully because water inside it can grow mold. For a tired parent, a teether that disappears into the cleaning routine you already run is a genuine relief.

No internal cavity, no mold risk

The single best design decision here is that the teether is fully solid with no internal cavity. That one choice eliminates the most notorious problem with the famous natural-rubber teether, which has a hole that lets water in and famously grows hidden internal mold that parents only discover by cutting the toy open. The Comotomo simply cannot do that, because there is no inside for water to enter. After four months of constant chewing and 12 dishwasher cycles, there was nothing to worry about, because there is nowhere for mold to hide.

The material itself is rated medical-grade silicone by Comotomo, and it is free of BPA, PVC, and phthalates. This is the same broad material category used in many medical applications, so the safety profile is reassuring, and there is no paint to wear off, no squeaker to seal, and no plush to stain. For parents who worry about what their baby is putting in their mouth for hours a day, the combination of solid silicone and no hidden cavity removes most of the anxiety.

Durability and grip

After four months and roughly 140 hours of chewing, our test unit shows essentially zero wear. The silicone is firm enough to resist permanent compression but soft enough to feel comforting on teething gums, and it has not torn, developed soft spots, or shown any surface deterioration. Based on that wear rate, I expect it to last well past twelve months of normal use, which makes the cost-per-month math excellent for something a baby uses every single day.

The grip is genuinely well thought out. The shape is hourglass-like, wider at the top and bottom with a narrower middle, and small hands naturally wrap around that middle. Across our test the baby rarely dropped it during chew sessions, partly because the grip is intuitive and partly because at 0.15 pounds it is light enough for an early-coordination baby to hold and maneuver. A teether the baby can actually keep hold of gets used; one that constantly falls on the floor does not.

Texture and engagement: the honest weak spot

The trade-off for all that maintenance-free simplicity is sensory variety, or rather the lack of it. The Comotomo is single-texture smooth silicone all the way through. There are no ridges, no dotted spots, no varied surfaces to explore, which is exactly what some babies crave during peak teething when novelty keeps them engaged. The natural-rubber giraffe wins on this dimension with its varied body, horns, and spots, and on its squeak.

In practice, our test baby returned to the Comotomo regularly and used it happily, but did not form the kind of attachment I have seen babies form with more characterful toys. It also has no squeak or rattle, so if you want a teether that doubles as a noisy plaything, this is not it. The color choices are limited too, just pink and blue. None of this undermines its core job, but if engagement and character are what you are after, you should know the Comotomo is deliberately plain.

Who should buy the Comotomo Silicone Teether?

Buy it if you want a maintenance-free teether that survives the dishwasher and can never grow mold, which is the real reason most parents seek out an alternative to natural rubber. It is also an excellent starter teether to use before deciding whether you even want a more elaborate character teether, because it is simple, safe, and easy to live with.

Skip it if you specifically want sensory variety in a single toy, with ridges, spots, and different surfaces to explore, or if you want a squeaker or rattle to keep your baby entertained. If you are hoping your baby forms an attachment to a beloved character toy, a more characterful teether is the better bet.

The verdict

Four months and 140 hours of chewing in, the Comotomo Silicone Baby Teether is the teether I would hand most families first. The dishwasher safety and the solid, cavity-free design solve the single most common complaint about natural-rubber teethers, the silicone has stayed soft and shown no wear, and the intuitive grip means it actually stays in the baby’s hands. It is not the most engaging toy in the basket and it makes no noise, but it does the one job a teether is supposed to do, quietly and without ongoing care decisions. For a low-risk, low-maintenance daily teether, this is the easy recommendation.
