How Do LED Teeth Whitening Systems Work?

LED teeth whitening systems work by using a whitening agent and an LED (light-emitting diode) light to brighten the teeth.

During LED teeth whitening, a whitening agent, usually made with hydrogen peroxide or carbamide peroxide, is applied to the teeth. The light is used for a given amount of time to activate the whitening agent, causing a chemical reaction that lifts stains from the teeth.

LED whitening is safe for at-home use. However, teeth whitening often involves putting bleach into your mouth, which can irritate the gums if not applied correctly. You should follow the manufacturer's instructions carefully when using an LED teeth whitening system to prevent unwanted side effects.

How to Use SmileDirect's Bright on™ Teeth Whitening Kit

Whitening your teeth with Bright on is a simple process:

  1. Before using the LED Teeth Whitening Kit, you should brush your teeth. Having clean teeth will help the teeth whitening gel absorb better.
  2. To start, remove the cap and slowly twist the bottom of the pin until you see a droplet of gel on the brush.
  3. Brush the gel on your six top and six bottom front teeth in a circular motion. The gel will foam and penetrate your teeth. Continue to slowly twist the bottom of the pen to dispense more gel as needed until your teeth are covered.
  4. From there, plug the LED accelerator light into your phone or USB port. Gently bite down, pull your lips over the mouthpiece, and use the light while the gel is on your teeth.
  5. Make sure your power adapter is fully plugged into your phone's port and wipe off any debris that may be present. If the light is plugged into your phone, your device must remain in an active state, not in sleeping mode or with a locked screen. Otherwise, the light may shut off prematurely. Unlock your phone and make sure that it has at least 50% battery to power the LED light for the full treatment time.
  6. After 5 minutes, remove the light and unplug it from your phone. Spit out the excess foam if needed – but don’t rinse. 
  7. Do not rinse, eat, or drink for 20 minutes after to allow the teeth whitening to continue to absorb into your teeth. After 20 minutes, you can rinse with water or mouthwash. You should start to see results in as little as one week.

How Often Should You Use SmileDirect's Bright on™?

According to SmileDirect's website, you should whiten your teeth every morning and night for one week. After this, you’ll whiten them once a week every six months to maintain results.

With the no-mess brush applicator, you have full control of the application as you paint the gel directly onto your teeth. Each treatment only takes 5 minutes, so it’s easy and convenient to get your best smile ever.


  • Eight pens for one year of whitening
  • Two full one-week treatments
  • Results last up to 6 months per one-week treatment
  • 5-minute treatments, twice daily for one week
  • Up to 9 shades whiter in only one week
  • Removes years of tough stains including red wine stains
  • Same enamel-safe whitening gel used by dentists
  • No-mess brush applicator
  • Fast-absorbing gel
  • Cool mint flavor
  • Vegan & gluten-free

How to Use SmileDirect's Teeth Whitening Pens

These premium teeth whitening pens work the same as any other over-the-counter whitening system like trays or whitening strips. These pens use the same whitening formula as the teeth whitening kits, and allow oxygen to penetrate and lighten teeth enamel.

Follow these simple steps:

  1. To use SmileDirectClub’s Teeth Whitening Pens, first start by brushing your teeth beforehand. With clean teeth, the whitening product will absorb better.
  2. From there, remove the cap and slowly twist the bottom of the pin until you see a droplet of gel form in the brush. Use the no-mess brush applicator to paint the gel directly onto your teeth, making sure to avoid the gums.
  3. Brush the gel on your six top and six bottom front teeth in a circular motion. Consider brushing your upper and lower premolars if they show in your smile. The gel will foam and penetrate your teeth. Continue to slowly twist the bottom of the pen to dispense more gel as needed until your teeth are covered.
  4. After five minutes, spit out any excess foam, but don’t rinse, eat, or drink for 20 minutes after. The teeth whitening will continue to absorb into your teeth. Once the 20-minute whitening period has passed, you can rinse with water or mouthwash.

How Often Should You Use SmileDirect's Whitening Pens?

You only need to use these pens for a week – once in the morning and once in the evening – to enjoy whiter teeth for six months. Because you receive two full treatments (a year's supply total), you won't have to restock when you repeat the whitening process in six months.

What People are Saying

The NewMouth team compiled reviews from four websites where you can purchase SmileDirectClub's teeth whitening products. We found over 2,000 customer reviews in total. Most of the reviews are positive, while a small percentage of them are negative or somewhere in the middle. Over 85 percent of the Amazon reviews are 4 stars or above.

Many of the positive reviews say the whitening products cause minimal to no sensitivity. Some mention instant results, while others say you'll see improvements after a few uses.

I can’t say enough good things about this whitening kit! I’ve used white strips for 10+ years and have always had success, but the process was time-consuming, messy, and I end up with a lot of tooth sensitivity and sore gums.

Amazon reviewer

I have tried numerous whitening agents over the years, including baking soda and peroxide. None have worked as fast as this one. I used to smoke and still drink dark soda. After 3 uses, the difference is amazing and surprising.

Walmart reviewer

Even though a majority of SmileDirectClub's reviews are positive across multiple sites, some people were not completely satisfied with the products.

However, keep in mind that people who have thin enamel or dental restorations cannot whiten their teeth. Some people are also more prone to sensitivity than others (and sensitivity is a common side effect of all teeth whitening, even professional treatment).

Neglecting to read the instructions carefully before use can also result in poor outcomes.

The pens are nice, but the mouthpiece didn’t work. At least they refunded me.

Amazon reviewer

For me, the system would be easier if it were strips that you put on your teeth, or if the mouthpiece was the kind you put the gel into and then put your teeth into. 

Walmart reviewer
