When selecting the ideal toothbrush, consumers and manufacturers must consider the material composition of the bristles, as it directly impacts cleaning efficacy, comfort, and durability. Among the most prevalent materials in the market are Polybutylene Terephthalate (PBT), Polyamide 612 (PA612), and Polyamide 610 (PA610). Each of these polymers offers a distinct balance of properties, making them suitable for different types of oral care products, from budget-friendly manual brushes to high-end electric toothbrush heads.
