Yes! Studies show 100% more plaque removal than manual brushing. Electric brushes deliver 8,000–40,000 movements/min (impossible by hand). They also reduce gingivitis and protect enamel with pressure sensors.

Oral-B: oscillating-rotating motion, dentist-recommended, more affordable. Sonicare: sonic technology, gentler on sensitive gums, quieter. Both are excellent. For beginners, Oral-B offers the best value.

Absolutely! The handle is cleaned and disinfected. You receive a new, unused brush head. Replace the head every 3 months as dentists recommend. As hygienic as a new unit.

Replacement heads cost $3–8 each (change every 3 months). That's $12–32/year—offset by savings at the dentist: fewer cavities, less scaling. A refurbished electric toothbrush is an investment in dental health.
