Q1: What makes the Oral-B Pro 680 different from other electric toothbrushes?

Q3: How long does the battery last on a full charge?
A: Up to 7–10 days with regular twice-daily use.

Q4: Can I use other Oral-B brush heads with this model?
A: Yes, it’s compatible with most Oral-B brush heads (except iO and Pulsonic series).

Q5: How often should I replace the brush head?
A: Every 3 months or when bristles become worn or fade in color.
