Each Toothbrush in Detail

Oral-B Vitality: Best Budget

The Vitality is the cheapest way to try an electric toothbrush. It uses Oral-B's small round head that rotates back and forth, has one cleaning mode and a 2-minute timer, and the bristles fade in colour when it's time for a new head. Replacement heads are the cheapest here.

Good for: first-timers on a tight budget, or a spare at a holiday home.
Trade-off: no pressure sensor, no 30-second pacer and a basic charger.

Philips Sonicare 2100: Best Budget Sonic

The 2100 gives you sonic cleaning (31,000 bristle movements, per Philips) for under $100. It has two intensities, Philips' Easy Start, which builds up power over your first 14 brushes, and a 2-minute timer that pulses every 30 seconds. The battery lasts up to 14 days.

Good for: anyone who wants a sonic brush without spending much.
Trade-off: no pressure sensor, and Sonicare heads cost more each year than Oral-B Vitality heads.

Oral-B iO2: Best Value Rotating Brush with a Pressure Sensor

The iO2 brings Oral-B's iO technology, a round head with micro-vibrating bristles, to a lower price. It has three modes, including Sensitive and Extra-Sensitive, and a pressure sensor that slows the brush and lights red when you press too hard.

Good for: people who press hard, and people who prefer the feel of a round, rotating head.
Trade-off: iO heads only fit iO handles, and Oral-B doesn't publish a battery life in days.

Philips Sonicare 4100: Best Value Sonic Brush with a Pressure Sensor

The 4100 adds what the 2100 lacks: a pressure sensor that vibrates to warn you when you brush too hard, plus Gentle and Clean modes at two intensities. Battery life is up to 21 days, and it has Easy Start and the 30-second pacer.

Good for: most people who want a reliable sonic brush at a fair price.
Trade-off: standard plastic heads and a shorter battery than some brushes.

Crescent Nest Sustainable Sonic Toothbrush: Best Battery Life and Lowest-Waste Heads

Our toothbrush is a sonic brush with up to 40,000 vibrations per minute and five modes: Clean, White, Polish, Sensitive and Massage. The battery lasts up to 60 days on one USB-C charge, so you can travel without a charger. The brush heads have FSC-certified bamboo bases and plant-based castor-oil bristles, and use around 85% less plastic than a conventional electric toothbrush head.

The handle is covered by a 2-year warranty and built to be repaired through our Circular Care System, rather than replaced when something goes wrong. Crescent Nest is a Certified B Corporation.

Good for: people who want a long battery, USB-C charging and less plastic waste, without paying premium prices.
Trade-off: there's no pressure sensor and no app, and the heads are only sold by us, not in supermarkets or pharmacies.

Oral-B iO5: Best Premium Rotating Brush

The iO5 has five modes (Daily Clean, Intense, Sensitive, Super Sensitive and Whitening) and a smart pressure sensor that shows whether you're brushing too hard, too softly or just right. The pack we found came with a travel case and three different brush heads.

Good for: people who want Oral-B's best cleaning feel and more feedback while they brush.
Trade-off: nearly double the price of the mid-range brushes.

Philips Sonicare DiamondClean 9000: Best Premium Sonic Brush

Philips' premium sonic brush has four modes and three intensities, a pressure sensor and an app that tracks your brushing. It looks the part, and its A3 Premium heads are well regarded.

Good for: people who want every feature and like tracking their brushing in an app.
Trade-off: the highest price here, the most expensive heads, and the battery is up to 14 days. Most Sonicare click-on heads fit across Sonicare handles, so you can save by using cheaper heads.

How to Choose

Sonic or rotating?

Both clean well. Sonic brushes vibrate side to side at high speed and feel like a buzz; rotating brushes have a small round head that spins and feels more like a polish. Most people find sonic a little gentler on the gums. Read our full sonic vs oscillating guide.

Do you need a pressure sensor?

If you tend to scrub hard, a pressure sensor is worth paying for, because brushing too hard is a common cause of gum recession and sensitivity. If you already brush lightly, it matters less. Either way, hold the brush like a pen and let it do the work.

Look at the cost of heads, not just the handle

You'll replace the head every 3 months, so over five years the heads can cost more than the toothbrush. Check the price of heads before you choose a handle.

Battery and charging

A 14-day battery is fine at home. If you travel often, a longer battery and USB-C charging mean one less charger to pack. See our guide to taking an electric toothbrush on a plane.

Sensitive teeth or braces

Choose a brush with a Sensitive mode and soft bristles. Read our guides to the best electric toothbrush for sensitive teeth and brushing braces with an electric toothbrush.

FAQs

What is the best electric toothbrush in NZ?
There isn't one best brush for everyone. For most people, a mid-range brush with a 2-minute timer and soft heads, like the Philips Sonicare 4100, Oral-B iO2 or Crescent Nest, does everything a dentist would ask. Pay more only for features you'll use, like an app.

Is an expensive electric toothbrush worth it?
Premium brushes add apps, more modes and smarter pressure sensors. They don't make the core clean very different. Brushing for 2 minutes, twice a day, with a soft head matters most.

How often should I replace the brush head?
Every 3 months, or sooner if the bristles splay. See when to replace your electric toothbrush head.

Where can I find independent test results?
Consumer NZ tests electric toothbrushes and publishes results for members.

How do I dispose of an old electric toothbrush?
It has a battery, so it goes to e-waste recycling, not the rubbish bin. See our recycling and disposal guide.
