Laifen toothbrush review: Features, guides, and deals

A new contender has entered the bathroom, and it’s already turning heads, today you can meet the Laifen Wave, a cutting-edge electric toothbrush now making waves in Australia after its global debut at CES 2024 and official launch in March.

This little tool blends dual-action technology (e.g. oscillation plus sonic vibration) for a deeper, more efficient clean without the elbow grease. With millions already switching to Laifen, curiosity is only growing. People are discovering what a truly smart toothbrush should feel like.

Laifen Wave outstanding features

• First, there’s the dual-action motor, which combines sonic vibration with mechanical oscillation. Translation: it cleans like two toothbrushes working in tandem, lifting plaque while massaging your gums.

• Then there’s the 2-minute smart timer and it gives your mind permission to zone out while your teeth get the exact clean they need.

• The refill heads snap on easily, and don’t come with the sticker shock most premium brushes sneak in.

• It’s also surprisingly quiet, with a soft, balanced hum that makes brushing feel more like a skincare step than a chore.

• As for when to use it? Honestly, all the time. Quick pre-coffee clean? Done. Post-lunch refresh? Feels light enough to not overdo it. Nightly deep-clean before bed? This is where the dual-action really shines.

• It’s also small and stylish enough to toss in your carry-on without guilt. Whether you’re the brush-for-10-seconds-and-run type or a full ritual-loving oral care nerd, Laifen Wave adjusts to your rhythm and looks good doing it.

Lafen toothbrush heads

Laifen offers three distinct toothbrush head options to cater to various oral care needs:

1. Gum Care: Designed with ultra-thin, soft bristles tapered to 0.02mm, this brush head cleans teeth and massages gums. Sensitive teeth or those seeking daily cleaning.
   

2. Super-Clean: Featuring premium DuPont bristles, this head reaches deep into interdental spaces for efficient cleaning. It removes plaque and debris for a thorough oral hygiene routine.
   

3. Ultra-Whitening: Equipped with specialized bristles, this brush head provides powerful cleaning aimed at brightening teeth, suitable for users focusing on stain removal and achieving a whiter smile.
   

Each of these brush heads is available in a convenient 3-pack priced at $14.99 AUD. Additionally, Laifen employs an advanced copper-free tufting process in their brush heads to inhibit bacterial growth.

Is the Laifen Wave waterproof

Yes, the Laifen Wave is fully waterproof (IPX7-rated, to be exact) which means it can handle being submerged in water for short periods without damage. So you can use it in the shower, rinse it under the tap, or let it sit on a wet sink without worry. For people like me (who absolutely don’t have time to tiptoe around a toothbrush), that peace of mind is everything.

But what’s impressive is that Laifen didn’t just slap on a waterproof label and call it a day. The entire design feels sealed and solid with no clunky seams or charging ports that make you hesitate. It’s built to live in real bathrooms, not spotless ones in showrooms.

How long does a Laifen toothbrush last

The Laifen Wave is built to last. On a full charge, the battery holds up for a solid 30 days of regular use (twice daily brushing, two minutes each session). That’s a full month of cordless brushing without having to worry about your brush dying mid-rinse. It’s the kind of quiet reliability that makes a real difference especially if you travel or just hate remembering to charge things.

In terms of long-term durability, the Laifen Wave holds up well over time thanks to its copper-free motor, tightly sealed waterproof design, and sturdy, minimal build. You’re not dealing with buttons that sink or parts that wiggle loose. Combine that with affordable replacement heads and a smart internal motor that’s engineered to resist wear, and you’ve got a toothbrush that feels more like a long-term investment than a quick upgrade.

How to put Laifen Wave in airplane mode

Putting your Laifen Wave into airplane mode is one of those small-but-smart features you didn’t know you needed until you toss it in your carry-on and realize it won’t turn on mid-flight.

To activate airplane mode, simply press and hold the power button for 5 seconds until the brush gives a quick vibration or light cue (depending on your model). This disables the motor and locks the button and prevents it from accidentally turning on in transit.

To exit airplane mode, just press and hold the button again for 5 seconds. You’ll feel another vibration, and the brush is back in action. No need for app controls or complicated settings, just one intuitive hold, and you’re good to go.

What is a dual-action electric toothbrush

In short: it’s a brush that multitasks. Instead of relying on just one type of motion, like most traditional electric brushes, dual-action models combine oscillation (think: side-to-side sweeping or rotating) with sonic vibration (tiny, high-speed pulses that shake loose plaque in the hard-to-reach places).

What makes this combo so effective is that it feels like you’re brushing smarter, not harder. You’re not grinding your brush back and forth or second-guessing your pressure. You’re letting the tech do the work. The Laifen Wave, for example, is one of those rare brushes that actually nails the dual-action promise.

Also, surprisingly quiet, oddly satisfying, and kind of addicting. Once you try it, going back to a one-trick brush feels… weirdly incomplete.
