• Medical-Grade Ultra-Soft Bristles: The bristles are made of ultra-fine food-grade nylon with a diameter of only 0.12-0.15mm (thinner than standard "soft" children’s toothbrushes). They are as gentle as tofu, able to clean primary teeth and gums without scratching enamel or causing gum bleeding—even for teething toddlers who may resist brushing.
• Ergonomic "Small Hand-Friendly" Handle: The handle is short, thick, and lightweight (about 15g), perfectly fitting the grip of 1.5-5-year-olds’ small hands. It has a non-slip rubberized surface (preventing slipping during parent-assisted brushing) and rounded edges (avoiding accidental scratches on the child’s mouth or face).
• Parent-Child "Oyako" Design Concept: The product is available in bright, child-attracting colors (e.g., mint green, baby pink) and often has a "mini adult version" matching design. This turns daily brushing into a parent-child interaction, reducing children’s resistance to brushing and helping them develop good habits early.
• Miniature Brush Head for Toddler Mouths: The brush head is only 1.5-2cm long (smaller than adult toothbrushes), specially designed for the narrow oral cavity of young children. It can easily reach back molars (a key area for food residue) without causing discomfort or gagging.

（specific ingredients are subject to product packaging; the following are core and common components）：
Extra Soft Bristle Material:
Ultra-Fine Food-Grade Nylon (0.12-0.15mm diameter): The core material of the bristles, sourced from Japanese medical-grade suppliers. It is non-toxic, odorless, and has excellent flexibility—able to bend with minimal pressure, avoiding damage to delicate primary teeth and gums. It meets Japan’s JIS L 1015 standard for bristle softness and is free of heavy metals (lead, mercury), phthalates, and formaldehyde.
Handle Material:
BPA-Free Polypropylene (PP) + Food-Grade Rubber: The main body is made of BPA-free PP (lightweight, durable, and heat-resistant to 80℃), and the grip area is covered with food-grade rubber (enhances non-slip performance and feels soft to the touch, reducing children’s resistance). Both materials are tested for oral safety and do not leach harmful substances when in contact with saliva.
Bristle Adhesive:
Medical-Grade Acrylic Adhesive: Used to fix bristles to the brush head. It is non-toxic, waterproof, and has strong adhesion (prevents bristles from falling off, avoiding accidental ingestion by children). It complies with Japan’s Ministry of Health, Labour and Welfare standards for oral contact adhesives.
Colorants:
FDA-Certified Food-Grade Pigments: Used to color the handle (e.g., mint green, baby pink). They are non-toxic, fade-resistant, and do not dissolve in water or saliva—ensuring no harmful substances enter the child’s body even with long-term use.

Pre-Brushing Preparation:
Wet the bristles with lukewarm water (max 37℃, close to body temperature—hot water damages ultra-soft bristles).
Squeeze a grain-of-rice-sized amount of toddler-specific fluoride-free toothpaste (for 1.5-3 years) or pea-sized low-fluoride toothpaste (for 3-5 years) onto the brush head. Avoid adult toothpaste (too high in fluoride, risk of ingestion).
Parent-Assisted Brushing Posture:
Hold the child securely (e.g., sit the child on your lap, face the same direction) and grip the toothbrush with your dominant hand (the child can hold the handle with their small hand to practice, but you control the force).
Gentle Brushing Movements:
Primary teeth surfaces: Use "light circular motions" (like drawing small circles) with minimal pressure—focus on cleaning the outer, inner, and chewing surfaces of each tooth (spend 10 seconds per area).
Gum line: Gently brush along the gum line (where plaque accumulates) to prevent gingivitis, but avoid pressing too hard (which may cause bleeding).
Total time: Brush for 1-2 minutes (use a children’s brushing song or timer to keep it fun).
Post-Brushing Care:
Rinse the child’s mouth with warm water (help them spit out toothpaste residue—avoid swallowing).
Rinse the toothbrush thoroughly, shake off excess water, and place it in an upright, ventilated holder (away from adult toothbrushes to prevent cross-contamination).
Replace the toothbrush every 1-2 months (softer bristles wear faster) or immediately if bristles fray.
