Most models use one of two approaches: a pull-to-jiggle or pull-activated mechanism that produces a gentle vibration, or an internal vibration motor with built-in controls. Listings with built-in motors often advertise multiple vibration settings, while pull-activated designs vibrate only when pulled.
Product listings cover a range of suggested ages, commonly stating "newborn and up," 0–3 years, or 0–5 years. Some descriptions use labels like "Ages 0m+" or "babies from birth+."
Care varies by product. Many teethers are intended for spot cleaning or wiping with a damp cloth. A few items note they are machine washable only after removing the sound or vibration module, so follow the product instructions before laundering.
Several listings highlight non-toxic materials and certifications. Common claims include OEKO-TEX STANDARD 100 certification, silicone or plastic teethers labeled non-toxic, and explicit BPA-free statements.
Common additional features include rattles, squeakers, crinkle fabric, shaped teethers, musical melodies and natural white-noise sounds, and in some sets light-up elements.
