Most cooling teethers are made from food-grade silicone. Other common materials include thermoplastic elastomers (TPE), ABS or other plastics. Product listings often specify silicone or TPE/ABS/plastic and will note when materials are BPA-, phthalate- or PVC-free.
Cooling teethers are marketed for a wide infant range—many are labeled from 0 months or newborn up to about 24 months. Common labels you’ll see include "0+ months" or "3+ months," reflecting suitability for early teething stages.
Teethers are sold as single units and in multi-packs. Listings range from one-piece items to multi-packs—commonly up to six pieces—so you can choose single or multiple-teether sets depending on your needs.
Teethers typically have ergonomic, lightweight shapes sized for small hands—rings and open designs are common for easy gripping. Some models include insulated or "not-cold" handles so the grip stays near room temperature while the chewing surface remains chilled.
