When sourcing oral care products, prioritize BPA-free plastics and food-grade silicone for manual tools. For electric toothbrushes, ensure the motor provides 31,000 to 40,000 vibrations per minute and features a lithium-ion battery with at least 30 days of standby time. Bristles should be DuPont Tynex or similar high-quality nylon with end-rounded tips to prevent gingival recession. For chemical products like toothpaste or mouthwash, verify the Fluoride content (typically 1000-1500ppm for adults) and the absence of harmful microbeads.
