How To Use Oral-B Precision Clean Replacement Brush Heads (10pcs):
1. Remove the old brush head: Gently pull the old brush head straight out of the handle to detach it.
2. Attach the new brush head: Align the new brush head with the metal shaft on the handle and push it in until it clicks into place.
3. Wet the brush head: Before turning on the toothbrush, wet the brush head and apply a pea-sized amount of toothpaste.
4. Turn on the toothbrush: Press the power button on the handle to turn on the toothbrush.
5. Brush your teeth: Hold the toothbrush at a 45-degree angle against your teeth and gums. Move the brush head in small circular motions, spending about 30 seconds on each quadrant of your mouth. Avoid pressing too hard, as the bristles will do the work for you.
