SmileDirectClub Whitening Kit Review

In this portion of the review we’ll be focusing on the Pro Whitening System Plus, the newest addition to SmileDirectClub’s line of whitening kits. 

We’ll explore how the product works, what you get for your money, safety, and what customers had to say about SmileDirectClub.

What Comes in the SmileDirectClub Whitening Kit

The kit includes the following.

  • One tube of proactive accelerator toothpaste

  • Two large whitening gel pens, each with sufficient gel for a complete treatment

  • Two whitening extender gel pens 

  • A rechargeable, reusable, wireless LED whitening light 

  • A charging case

SmileDirectClub - What Comes In The Kit

SmileDirectClub Whitening Kit Ingredients

The Pro Whitening System uses enamel-safe ingredients, including the following. 

  • Hydrated silica

  • Sodium hexametaphosphate

  • Polyethylene glycol

  • Hydrogen peroxide 

  • Peppermint oil 

  • Hydroxyapatite

  • Potassium nitrate

How Does SmileDirectClub’s Whitening Kit Work?

The Pro Whitening System Plus utilizes three products to prepare the teeth, whiten them, and help protect and prolong results. 

  1. The ProActivate™ Whitening Accelerator prepares the teeth for whitening by opening up the pores of the teeth to enable the whitening to absorb better. The enamel and dentine-safe formula causes little if any sensitivity and works to give a deep clean.

  1. The ProBrighten Premium Teeth Whitening Gel is a hydrogen peroxide-based gel that works to break down complex stain molecules. While 20-light LED technology doesn’t whiten teeth, it  is used to accelerate the whitening gel so that it gets to work faster.

  1. The hydroxyapatite contained in the ProLong Whitening Extender Gel helps to close the pores of the teeth, prevent staining beverages and foods from adhering and restaining. It also slows down plaque formation. 

How To Use SmileDirectClub’s Whitening Kit

Using the Pro Whitening System Plus has a few more steps than some at-home whitening procedures, but the steps are quite simple.

  1. Apply accelerator toothpaste to a toothbrush and brush your teeth. Spit out any excess foam, but don’t rinse your mouth.  

  2. Apply teeth whitening gel to your toothbrush. 

  3. Brush teeth until gel foams. 

  4. Turn on the wireless whitening light and insert it into your mouth and bite down gently.

  5. Remove the light after five minutes.

  6. Spit out excess gel, but do not rinse your mouth.

  7. Rinse and dry the mouth tray.

  8. Brush your teeth with a tiny droplet of ProLong Whitening Extender to extend the whitening process. 

It’s best to whiten the teeth once in the morning and once at night, but make sure not to eat or drink for 20 minutes after whitening. When the kit is used twice a day for seven days, SDC states that your teeth may become up to nine shades lighter. 

Most reviews stated that sensitivity was minimal with this product, while other reviews stated that they did notice sensitivity issues particularly in the first few hours after treatment. 

SmileDirectClub - How To Use

Is SmileDirectClub Safe or Will it Damage Your Teeth?

Smile Direct teeth whitening kits and products are safe and comply with all FDA regulations. However, Smile Direct advises against women who are pregnant or breastfeeding using teeth-whitening products.  Also keep in mind that people with thin enamel cannot whiten their teeth, and restorations do not respond to teeth whitening.

If you are concerned about how whitening will affect your dental health, it’s always best to talk to your dentist before starting treatment. 

Does SmileDirectClub Actually Work?

Yes, without a doubt. According to customer reviews found on sites like Amazon, most people noticed a difference in the color of their teeth—some right away. That said, there were some complaints about sensitivity and sore gums.

SmileDirectClub states that people only need two to four 1-week-long treatments to maintain a whiter smile for a year. Of course, this varies according to smoking habits, dietary intake, and age. 

The company also offers a 60-day guarantee and a product return policy that offers a full or partial refund depending on circumstances.

SmileDirectClub vs Hismile

Both brands offer LED teeth whitening kits, but Hismile’s kit is peroxide-free, meaning there may be fewer issues surrounding teeth sensitivity. That said, Smile Direct’s whitening kit is less than $100.Throw into the mix the potential for longer lasting results and on paper, SDC’s kit represents good value for money. 

SmileDirectCub vs Laughland

Laughland is currently offering a one-time-only price for their wireless teeth whitening kit at an unbeatable low price of just $9.00. While Laughland claims to produce optimal results in six days, reviews suggest that its whitening treatment takes longer to achieve optimal results and only lasts up to three months compared to Smile Direct’s six months.

SmileDirectClub vs NewSmile 

SmileDirectClub uses LED light technology and provides sufficient whitening gel in its kit for two whitening treatments lasting up to a year. NewSmile only offers a teeth-whitening foam that replaces a regular toothpaste. NewSmile’s results are said to last for up to a month, meaning that Smile Direct has longer-lasting results and more bang for your buck. 

Other Smile Direct Products

Fast-Dissolving Teeth Whitening Strips

Subtitle - Fast whitening without the mess

SmileDirectClub - Other Products

Starting price - $30

Duration – Once a day for seven days 

Results – Typically last up to three months

Fast-dissolving teeth-whitening strips are ideal for people with sensitive teeth wanting quick results without the mess. These strips are easy and convenient to use, and because they dissolve, they can even be worn when you’re sleeping. 

Smile Direct dissolvable whitening strips need only be worn for 15-20 minutes, about half the time of most other leading brands. When worn for seven consecutive days, the company say that teeth can whiten up to nine shades. However, this is dependent upon the starting shade.

Pros

  • Fast dissolving 

  • Less sensitivity

  • May whiten up to nine shades after seven-day treatment

Cons 

  • Need to prevent tongue from coming into contact with whitening gel 

  • Shouldn’t eat or drink for 15-20 minutes after treatment 

Bright On Teeth Whitening Pens

Subtitle – Instant whitening without the fuss 

SmileDirectClub - Other Products

Starting price -  $45 

Duration -  Use twice a day for one week

Results – Can last up to six months 

Containing the same enamel-safe bleaching agent used by dentists, these pens provide whitening effects with a much simpler process than the SDC whitening kit. The easy-to-use pen design enables  application of the whitening gel directly onto the teeth for zero mess. 

Use in the morning and the evening for a week to remove stains and discoloration and benefit from a brighter smile for up to six months. Treatments should be repeated every six months, and the eight pens provide a full year of whitening.

Pros 

  • Up to nine shades whiter in a week

  • Little to no sensitivity

  • Cool mint flavor

Cons 

  • The gel can be tricky to dispense

  • No rinsing, eating, or drinking for 20 minutes after whitening

Is SmileDirectClub’s Teeth Whitening Kit Worth It?

Absolutely! According to many reviews, people trust SmileDirectClub, like the product, and would happily recommend it to their friends. Although some report sensitivity, the product is generally safe when used as recommended. 

While applying the treatment has a lot of steps, the extra pre-treatment and tooth protection gels can help ensure an effective treatment. Overall treatment only lasts for a week of twice-daily applications. Given that the cost of SmileDirectClub’s LED whitening system is on the lower end of the spectrum for at-home tooth-whitening products and the kit provides whitening ingredients for up to a year, it provides good value for money and solid results.

Great club and has great opportunities to have your teeth whitened, straightened or anything else that you might want done. They make your smile look so much whiter and straighter. I would recommend this to my friends and family. It's a little expensive but for the price it's worth it.

9 months ago

The price is a bit expensive and the amount of whitening gel you get per container for the price you pay is not enough in my opinion, but the product does work well.

9 months ago

I wanted white teeth for my vacation and heard good things about smile direct club. It's expensive and not worth the money.

7 months ago

I did not get the promised smile. They want more money. I was very disappointed with the service.

8 months ago

The product did not fit my teeth. And often cut into my gumline and made me bleed. They always had to resend me new trays. I had to stop using the product because it was affecting my jaw.
