Can the LED teeth whitening kits by HiSmile, Laughland and Smile Direct Club compete with established teeth whitening brands? Do they work, and what do they cost? If your teeth are starting to look a little … less pearly white after a few years of enjoying coffee, red wine (or life!) read on and find out if these new options can help you.

A few years ago you had to go to the dentist to brighten your smile. But, then Crest Whitening Strips came along and introduced the idea of DIY teeth whitening. (OK, maybe there were some super strange old-timey products back in the day).



A new crop of direct-to-consumer options have hit the scene offering a more effective (and less painful) solution. Want to experience the latest in teeth whitening technology? LED mouthguard kits are more intensive than regular whitening strips and becoming just as popular.

Believe it or not, Silicon Valley types are noticing that people want brighter teeth and are getting into the game. Some of the most notable technology startups offering new options include HiSmile (, Laughland (, and Smile Direct Club ( In this article we compare the top LED teeth whitening treatments so you can choose the best one.



How are HiSmile, Laughland and Smile Direct Club different from traditional whitening options?

Traditionally, whitening options available to the public include:



Whitening trays from your dentist

It’s helpful to know what you’re getting, so let’s cover the difference between these newFANGled (pun-intended) products vs alternative methods of whitening your teeth. Many people decide to get it done professionally by a dentist. The DDS does the work for you, has the expertise, and uses clinical grade products to get you results — but you’ll probably end up spending over $600, not to mention the hassle of getting there, and spending over an hour in a waiting room listening to smooth jazz. Long-story short: it tends to work, but there’s a high-price tag. (Side note: smooth jazz does nothing to relax me anymore; I associate it with teeth pain.)



Alternatively, dentists now offer at-home options that let you brighten your teeth in the comfort of your own bathroom. These customize trays typically costs up to $400 and require a trip to the dentist for an initial mold / impression. More smooth jazz…



At-home whitening strips, pastes, pens, and kits

Finally, there’s a range of over-the-counter teeth whitening options that you can buy at a pharmacy, retail store, or online without ever speaking to a dentist. Ranging from $40 to $100 per package, they surely are a lot more affordable than “professional”, dentist-prescribed treatments, but they’re generally not as effective and take longer to see results. At-home whiteners come in a variety of shapes and sizes, including trays with gel, whitening strips, toothpastes, gums, pens, and mouthwashes. The different choices vary in how they lighten teeth, and some work better than others.



Modern  LED whitening devices

Nowadays dentists use a series of LED curing lights or lasers to activate the peroxide in the bleaching agent, which yields optimal bleaching results. Over-the-counter whitening treatments used to use only peroxide (or maybe an abrasive) to work on stains. Only evil geniuses and dentists  used to be able to afford to offer lasers…



But today we have new, affordable LED brightening solutions from HiSmile, Laughland, and Smile Direct Club. These players claim to offer the best of both worlds: professional dental treatment efficacy for an at-home price — all without ever having to step foot in a dentist’s office (no smooth jazz!). Do I have your attention yet?



How do LED whiteners compare vs Crest Whitening Strips?

Zimba and Crest Strips offer popular over-the-counter whitening strips that are proven effective for millions. I personally used strips for years, and in general, they are safe, effective, relatively affordable, and the only common complaint is feeling minor tooth sensitivity or pain shortly after using them. LED whiteners are similar to crest whitening strips in that they  both expose your teeth to a bleaching agent, but LED whiteners also use lights to better activate the agent — typically yielding better results. 



How do LED teeth whitening treatments work?


Because you and your friends all have a smartphones, you are likely getting more photos of yourself taken than any other generation. That’s more chances to record the color of your teeth! But did you know that smartphones also can facilitate teeth whitening? I’m not talking about snapchat and Instagram filters. No, Smile Direct Club and Laughland actually use your smartphone to work.

In fact a smartphone is all you’ll need to use these products once you receive your kit in the mail. Either Android or iPhone will do. If you’re one of the remaining few with a flip phone, you can still use HiSmile, which uses a battery instead of a smartphone as the power source for the LED light.


Here’s a quick review of how these new LED teeth brighteners work:


  1. First you order your kit through the website of whichever company you choose.
  2. You may need to answer some questions to personalize the process, depending on the company.
  3. Feel free to listen to smooth jazz to get you in the mood.
  4. You’ll be sent your kit, which will conveniently come to your mailbox or doorstep, saving you a trip to the dentist. Each kit includes a whitening gel, a mouth tray, and an LED light component.
  5. The process of whitening varies slightly by company, but in every case you start by brushing your chompers.
  6. Next, you apply the whitening gel to either your teeth or the tray. Each company is a bit different; for example, Smile Direct Club whitening has you apply the gel to your pearly whites using a pen. After you’ve got the gel in place, you power on the LED light — either by hooking it up to your smartphone or pressing the battery-operated unit.
  7. You’ll leave the tray in your mouth for about 10 to 15 minutes.
  8. Finally, you will rinsing out your mouth and washing the tray.

That’s it, you’re done until the next treatment. To see the most robust results, you’ll repeat the process daily for about a week, but most start to see gradual improvements day by day. It’s worth reiterating that the true innovation that LED light that comes with these direct-to-consumer choices helps the process work faster and more effectively than over-the-counter treatments that don’t use the light.


Now you know how your smartphone can help you get a better smile, without a fancy instagram filter!

HiSmile vs Laughland vs Smile Direct Club: Which is best?


Given that these three options all work in pretty much the same way (gel + tray + light) and claim to show results in essentially the same amount of time (6-7 days), why should you choose one company over the other? Is one the clear leader amongst the three? The answer is a bit nuanced, but ultimately you should pick the one you think will best fit your needs. It’s a personal decision that we’ll try to make a bit easier for you with this comparison. Use this chart to compare HiSmile, Laughland, and Smile Direct Club head-to-head.

Review of Laughland teeth whitening

Source: Laughland

The distinguishing feature of Laughland is their personalized approach (and the fact that they have a dot at the end of their name, which is kind of odd. Also they do not capitalize their name, which is strange). The company has you fill out a questionnaire to find out more about your needs and lifestyle before customizing the treatment to you.


Laughland claims to be the only whitening product that is personalized, and its customization process includes a variety of factors that include how you brush, your diet, whether you recently had dental work, and the level of sensitivity you experience in your teeth. I’m pretty sure my dentist offers super personalized treatment as well, but the extra dose of smooth jazz, the cost and the fact that I’ve got to get into the city to see her makes Laughland a cool option.

Laughland also uses all-natural ingredients. These include aloe leaf juice, pomegranate seed extract, chamomile flower, and menthol mint. Does this stuff make a difference? I have no idea.


This is the best bet if you are not sure if any of these teeth whitening options are going to work, because they offer a money back guarantee. You can get a free kit or your money back if you’re unsatisfied. No questions asked. So if you are unsure, go with Laughland.
