Frequently Asked Questions
What’s the difference between sonic and ultrasonic electric toothbrushes?
Sonic brushes vibrate 20,000–40,000 times per minute with visible movement, while ultrasonic brushes vibrate at similar speeds but with micro-vibrations less visible to the eye. Both clean effectively; the choice is personal preference. Fairywill models use ultrasonic technology, while many lower-cost options use sonic. Neither is objectively “better”—it depends on sensitivity and cleaning preference.
Are replacement heads expensive?
Not necessarily. The Fairywill models include 5–10 replacement heads per bundle, and third-party heads cost £2–5 each. Oral-B iO heads run £5–8 per head but last longer. Buying bundled replacement packs (like the 8-pack shown at £14.99) reduces per-head cost significantly versus single replacements.
Do I need the app and smart features?
No. Smart features (app tracking, AI feedback) are helpful if you struggle with proper brushing technique or want data-driven insights, but they don’t affect cleaning power. Budget models like Fairywill still clean thoroughly without connectivity—you just miss real-time guidance.
How long do electric toothbrushes last before replacement?
Most electric toothbrushes last 3–5 years with proper care. You replace the brush head every 3 months, not the whole unit. Battery degradation (slower charging, shorter runtime) is the main reason to replace after 5 years. Fairywill and Oral-B models are both durable, though Oral-B typically holds charge longer over time.
