1. Introduction
Thank you for choosing YTEATH PRO replacement brush heads. These brush heads are specifically designed for use with YTEATH PRO Y05U and Y08U electric toothbrushes, providing effective cleaning and optimal oral hygiene. This manual provides essential information for installation, usage, and maintenance to ensure the best performance and longevity of your brush heads.
2. Setup and Installation
To install a new brush head, align the brush head with the metal shaft of your YTEATH PRO Y05U or Y08U electric toothbrush handle. Push the brush head down firmly until it clicks securely into place. Ensure the brush head is fully seated to prevent it from detaching during use.

To remove a brush head, simply pull it straight up from the toothbrush handle.
3. Operating Instructions
- Moisten Bristles: Wet the brush head bristles with water.
- Apply Toothpaste: Apply a small, pea-sized amount of toothpaste to the bristles.
- Position Brush: Place the brush head against your teeth at a slight angle towards the gumline.
- Start Brushing: Turn on your YTEATH PRO electric toothbrush. Guide the brush head slowly across each tooth surface, allowing the sonic vibrations to clean effectively. Do not scrub vigorously.
- Brush All Surfaces: Ensure you brush all surfaces of your teeth (outer, inner, and chewing surfaces).
- Rinse: After brushing, rinse your mouth and the brush head thoroughly with water.

4. Maintenance and Replacement
4.1 Cleaning the Brush Head
After each use, rinse the brush head thoroughly under running water to remove any toothpaste residue and debris. Store the toothbrush upright in a clean, dry place to allow the brush head to air dry. Do not use harsh cleaning agents or extremely hot water on the brush head.
4.2 When to Replace Brush Heads
For optimal oral hygiene and cleaning performance, it is recommended to replace your brush head every 3 months. You should also replace the brush head sooner if the bristles become frayed, bent, or worn. The DuPont nylon bristles are designed with indicator bristles that fade in color over time, signaling when a replacement is due.

5. Troubleshooting
- Brush head does not fit securely: Ensure the brush head is correctly aligned with the toothbrush shaft and pushed down firmly until it clicks into place.
- Reduced cleaning performance: Check if the brush head bristles are worn or frayed. Replace the brush head if necessary, as worn bristles are less effective at cleaning.
- Bristles fading quickly: This is a normal indicator for replacement. If fading occurs significantly faster than 3 months, it might indicate excessive pressure during brushing.
