Laifen Wave Electric Toothbrush Review Feature Mian scaled

Any links to online stores should be assumed to be affiliates. The company or PR agency provides all or most review samples. They have no control over my content, and I provide my honest opinion.

I have previously reviewed the Laifen Swift Special Hair Dryer, I don’t have enough hair to appreciate it, but my partner loves it and continues to use it.

Laifen is now hoping to shake up the electric toothbrush market with the new Laifen Wave. This small toothbrush boasts an impressive array of features, including its proprietary servo system, which combines an industrial-grade permanent magnet synchronous motor with an electronic control system and companion app to adjust the settings and track cleaning.

Technology and Design

Laifen Wave Electric Toothbrush Design

The Laifen Wave employs advanced motor technology commonly found in mechanical arms and robotic devices. It uses a linear hall sensor inside the servo system to obtain accurate position data and control oscillations with a precision of 0.1°. This results in a wide oscillation angle that aligns with the Bass brushing method recommended by dentists.

The brush head features bristles that are 0.02 mm wide at the tip and have a 90% rate of narrowing. Combined with the 60° rotation, the Wave effectively reaches deeper into the teeth for superior cleaning.

One notable feature of the Wave’s brush heads is the dynamic balancing design, which enhances brushing comfort. A metal counterweight is placed at the back of the head, a new feature that minimises motor shaft vibrations and results in quieter and gentler oscillations on the gums.

Laifen App

To fully customise the settings on the Laifen Wave, users must download the Laifen App, as the toothbrush itself only has a single button with limited functionality. The app allows users to adjust brushing modes, track their brushing habits, and receive personalised recommendations for improving their oral hygiene routine.


One issue with this brush is the lack of a pressure sensor, so you will likely inadvertently brush too aggressively, which can cause damage to your enamel. It is a common issue with affordable electric toothbrushes, but it is still a bit disappointing.

Where it excels is the claimed 66,000 vibrations per minute, which is much more than that of a Philips Sonicare.

The toothbrush heads are quite a bit smaller than the brush heads on my other options, and I quite like them as they allow me to easily brush the harder-to-reach spots in my mouth.

I was impressed with the overall results; my teeth feel much cleaner in comparison to when I use my normal brush, and subjectively, my teeth seem a bit whiter.

Battery and Charging

Another gripe is that this toothbrush uses a propriety magnetic charger. It works well, but I am a nightmare because of losing chargers. With the 30-day battery life, I will almost certainly put it away somewhere and forget where it is (or, more likely, my partner will tidy up after me and not tell me where it is).

On the flip side, I have used the toothbrush the past few weeks, and it is still going strong, which is much better than many competing options from big brand names.

Replacement Brush Heads Availability and Price

One issue I have with many of these affordable electric toothbrushes from lesser-known brands is the availability and price of toothbrush heads.

The Evowera Planck O1, which I have been personally using for the past 18 months, is no longer available to buy in the UK or from Evowera, and there are no brush heads available to buy anymore. Even when you could buy them, they were priced at a ridiculous £23 for 3.

Things are better but not great for Laifen. The Laifen website lists a three-pack of brush heads for €10 (£8.56) or €17(£14.55) for 6, but at the time of writing, they are out of stock. Hopefully this is just because it is a new product.

You can buy a ten-pack on Aliexpress for just $7.42+, which is a bargain, but they don’t ship to the UK.

Price and Alternative Options

The Laifen Wave is available to buy now and is priced at €79.99, which works out as £69.

Shipping is free with a 30-day money-back guarantee.

It is a bit hard to suggest alternatives as there are so many toothbrushes available at varying prices, and each brand uses various marketing terms to suggest they are amazing.

A quick look on Amazon shows that you can get:

  • Philips Sonicare ProtectiveClean 4300 for around £80
  • Oral-B Smart 6 for around £79

I have previously reviewed the Bitvae R2, which is available for just £25 and includes 8 brush heads and has USB-C charging. Replacements cost £10 for 5. I much prefer the cleaning performance of the Laifen Wave, but it is hard to ignore the appeal of an affordable toothbrush with easy charging and cheap brush heads.


The Laifen Wave electric toothbrush is a promising addition to the oral care market, offering advanced features and impressive cleaning performance. Its compact design, multiple brushing modes, and long battery life make it a convenient and effective option for maintaining oral hygiene.

The Wave’s advanced motor technology and dynamic balancing design contribute to its thorough cleaning capabilities and comfortable brushing experience. The smaller brush heads allow for easy access to hard-to-reach areas, ensuring a comprehensive clean.

However, the lack of a pressure sensor and the proprietary magnetic charger are potential drawbacks to consider. The availability and price of replacement brush heads may also be a concern for some users, particularly those in the UK.

When compared to alternative options in a similar price range, such as the Philips Sonicare ProtectiveClean 4300 and the Oral-B Smart 6, the Laifen Wave holds its own in terms of features and performance. For those seeking a more affordable option, the Bitvae R2 offers a compelling combination of value and functionality, albeit with slightly lower cleaning performance compared to the Wave.

Its cleaning effectiveness and comfortable design make it a worthwhile investment in oral health, provided that replacement brush heads remain readily available and reasonably priced.
