REVIEW – My dentist tells me I brush my teeth too hard. Been telling me that for years. I tried softer brushes, but my teeth never felt as clean. As a result, I went with an electric toothbrush. It was just a cheap one my wife found on Amazon. It was fine. My dentist said my gums looked better, but the hygienist still had to scrape my teeth more than I would’ve liked. So when the Laifen Wave electric toothbrush came along, I was eager to try something better than what I was currently using. I mean, it’s an electric toothbrush. How much better could it be? Well, let’s talk about that.

What is it?

The Laifen Wave is an electric toothbrush that vibrates and oscillates with three different finishes and three different types of brush heads for all your dental cleaning needs.

Design and features

To get this out of the way, the Laifen Wave electric toothbrush comes in three different finishes. They have one in ABS plastic, one in an aluminum alloy, and one in stainless steel. I received the ABS version and I’m perfectly fine with that. It looks much better than the one I currently use and not as much as the torture devices my kids chose. Laifen uses “nano molding technology in an electric toothbrush, a process commonly employed in flagship smartphones. This process creates a secure bond between the outer shell and internal structure, guaranteeing extraordinary stability and durability”. I can attest that the Wave feels pretty premium in the hand. It has a good heft and the body is pretty much seamless. The seam you see in the picture below is a sticker with instructions to get you started. Once that’s removed, it’s as smooth as glass. The button is pressure sensitive using an optical sensor that detects pressure and distance to activate the Wave.

The Laifen Wave electric toothbrush has three different brush modes and can connect to a Laifen app on your phone. The app gives you the ability to change the intensity of brushing so you can make it faster or slower via Bluetooth. I’d love to show you some pics of it in action but the app stopped working correctly and I can’t get it to connect correctly to the toothbrush anymore. Do you need it to use the Wave? No. It works just fine without it. I played around with it when I first got the toothbrush but, the default settings for mode 1 are plenty strong enough. Additionally, you can switch modes on the brush itself.

And because it does use Bluetooth, it even has an airplane mode.

To charge the Laifen Wave electric toothbrush, it comes with a nice braided magnetic USB cable.

The problem I see here is if the cable stops working, you can’t go and grab another from the neighborhood department store. You’d have to order it directly from Laifen and currently, it’s not offered on their website. It is nice though, not have to line anything up perfectly to get it to charge. If you get close enough, the magnets take care of that for you. The only thing I don’t like is the charging contacts are on the bottom of the Wave, so it has to lie on its side to charge.

As I said earlier, the Laifen Wave comes with 3 different brush heads.

laifen wave 4

The blue one is for super cleaning and is the one I’ve decided to use. The grey one is for gum care and feels to be softer than the other 2, while the purple is for whitening and seems to be the stiffest. These heads appear proprietary, but I don’t know that for certain. None of the other heads I have for my previous toothbrush would fit since the hole for the shaft is way too big. Here’s a shot of the shaft on the Wave for reference.

I love the Laifen Wave electric toothbrush. I’ve always heard and read how other brands of toothbrushes leave you with that just left the dentist feeling, but the ones I used always came up short. The Laifen Wave has a powerful motor and allows for the brush to oscillate at 60 degrees while simultaneously vibrating up to 66,000 times a minute. Battery life has been great as well. I’ve used it for almost a month now and haven’t had to recharge it since I initially charged it when I first got it. Laifen says the Wave has an IPX7 waterproof rating which I guess is good since, you know, it’s a toothbrush and water will be a factor. The grey and blue brush heads work well. The grey feels very soft and has already started to age on me so I switched to the blue. I’ll probably steer clear of the purple one since it seems to be the stiffest and I was already getting the stick eye from my dentist for brushing too hard. Speaking of replacements, when I first got the Laifen Wave, replacements weren’t available on their site. I get it. It’s a new product so they were still in the process of getting everything ready for launch. They are now available for purchase, and much to my relief and surprise, they’re only $9.99 for a pack of 3. I’ve included a video with a portion in slow-mo to try to give you an idea of what it looks like during use.

What I like about Laifen Wave electric toothbrush

  • Excellent build quality
  • Multiple configurable modes of use
  • Affordable replacement heads
  • Long battery life
  • Strong motor
  • Oscillation and vibration

What needs to be improved?

  • Proprietary charging cable
  • Charging contacts on the bottom

Final thoughts

If anyone is in the market for an electric toothbrush, they should really look into the Laifen Wave. It’s much less expensive than others available. It also does a better job of cleaning my teeth than any other ones I’ve used in the past. Replacement heads are less expensive too. I will continue to use the Laifen Wave for the foreseeable future and I will be buying some more heads for it. I’m in for the long haul with this one. Now I just have to wait for my next dental appointment to see if my dentist approves.

Price: $69.99 for the ABS model
