04 / Common questions

The questions we hear most often, answered briefly and without sales pitches.

Things people ask before buying.

01 What is Sonicare? +
A line of electric toothbrushes that use sonic vibration (over 31,000 strokes per minute) to clean teeth more thoroughly than manual brushing. Premium models add pressure sensors, multiple cleaning modes, and Bluetooth.
02 How do I choose the right model? +
Start with budget. Under $50 gets you the basics (2100, 4100). $50–$150 gets you smart features and better battery (5100–7500). $150+ buys flagship modes, three-week battery, and AI coaching (9100–9900). Then narrow by priority: gum health, whitening, or family use.
03 How long does the battery last? +
7 to 21 days on a single charge, depending on the model and how often you brush. Premium models (9000+ series) last up to 3 weeks; budget models average 2 weeks. A full charge takes 8 to 24 hours.
04 Are all brush heads compatible? +
Most heads work across the same generation, but some lines (like DiamondClean) use proprietary heads. Always check the model number before buying replacements. Most brushes accept both standard and C-shaped head variants.
05 What does BrushSync do? +
It detects which brush head is attached and tunes the motor accordingly. It also tracks usage and reminds you to replace the head — usually every three months — so cleaning quality stays consistent.
06 Is a sonic brush worth the money? +
Dental research is generally favorable. Over five years, the per-use cost is comparable to a manual brush. If you have sensitive gums, bleeding, or want measurable plaque reduction, the upgrade pays off. For everyone else, a budget model is more than enough.
