Personal care
Electric toothbrushes range from ₹1,000 (≈$12) battery units to ₹20,000 (≈$240) app-connected handles — yet dentists say the cleaning difference between a good ₹3,000 (≈$36) brush and the flagship is small. What actually changes outcomes is the brushing technology, a pressure sensor, and how cheaply you can keep buying replacement heads. This guide decodes the spec sheet so you pay for cleaning, not for an app.
Quick answer
Pick oscillating-rotating or sonic — both clean better than a manual brush.
Insist on a pressure sensor and a 2-minute timer; these two features change outcomes.
Check replacement-head price and availability before you buy the handle.
Bluetooth, AI coaching and five extra modes are optional.

Answer all 3 questions to see the spec sheet to shop with.
Buy it locally
Sometimes the local dealer beats online on price, installation or the exchange offer. Tell us where you are and we'll list nearby stores. We don't rank or take money from any shop; results come from Google Maps.
The area you enter, or coordinates rounded to about 1 km if you use your location, are sent to Google Maps through Lovable to find places. Lookups are temporarily cached for up to 30 minutes.
Round heads that spin and pulse, versus vibrating heads that sweep side to side.
Why it matters
Both beat manual brushing in trials. Rotating heads clean one tooth at a time; sonic heads cover more area and feel gentler.
What to check
Pick the motion you'll actually use twice a day — comfort decides consistency.
A light or pulse that warns when you press too hard.
Why it matters
Hard brushing wears enamel and recedes gums — the most common electric-brush mistake.
What to check
A visible light ring beats a subtle vibration you'll never notice.
Replacement heads every 3 months, forever.
Why it matters
Heads often cost ₹300–₹800 (≈$3.60–$9.60) each; over three years they can exceed the handle price.
What to check
Check head prices and local stock before buying the handle.
Two-minute timer with 30-second pulses to move between mouth quadrants.
Why it matters
Most people brush for under a minute; the pacer fixes coverage, not just duration.
What to check
Standard on decent models — treat its absence as a red flag.
Days per charge and whether it charges on a stand, USB, or replaceable batteries.
Why it matters
Lithium handles last 2–4 weeks; battery units are cheap travel backups.
What to check
Proprietary chargers are a travel nuisance; USB charging is more convenient.
Whitening, sensitive, gum-care modes; Bluetooth brushing reports.
Why it matters
Sensitive mode is genuinely useful; the rest rarely change outcomes.
What to check
Don't pay a ₹5,000 (≈$60) premium for an app you'll open twice.
₹1,500–₹4,000 (≈$18–$48) covers the sweet spot. Flagships above ₹8,000 (≈$96) add polish, not cleaner teeth.
