Best For

While Glo’s patented technology can be used by anyone looking to brighten their smile, the treatment is particularly well-suited for people with:

• Sensitive teeth and gums
• Yellowing teeth
• Coffee and wine stains
• Nicotine stains
• General color deterioration

How Does it Work?

Glo uses a simple application process. Here’s how it works if this is your first time using the treatment:

• Use the lip treatment to prepare your lips and keep them moist during treatment.
• Apply the Glo serum onto the applicator brush provided, and then brush the applicator along the fronts of your teeth.
• Place the LED light mouthpiece into your mouth and press start (or use the app to get it started).
• Leave the mouthpiece in for 8 minutes; it will turn off automatically when the treatment is completed.
• Glo recommends waiting 20 minutes after treatment before you eat, drink, or brush your teeth).

Treatments should be performed three times a day for five to seven consecutive days. You should see results anywhere from five to seven days after starting the treatment. One thing that could be annoying is that you’ll need to repeat treatment every six months, but this is pretty standard for this type of whitening treatment.

What Sets Glo Apart?

Glo combines the power of LED light treatment with its own whitening gel to maximize results. Dr. Levine created the whitening formula after years of working in the dental field, and the LED treatment is FDA-registered, so that’s always a plus.

Glo also gives a 30-day money-back guarantee if you aren’t happy with the results. Glo is known for having great customer service, as is evident from the positive reviews and responses from thousands of online testimonials. What’s more, Glo products are all cruelty and gluten-free, vegan-friendly, and made in the USA. All ingredients are of high quality and safe for human use.

Finally, Glo gives 10% of all proceeds to charity. Every time someone makes a purchase, Glo provides dental health assistance to under-privileged kids and families. 

Pricing

Glo has a pretty basic pricing structure. You can purchase the whole kit if it’s your first time using the product. After that, you can purchase packs of just the whitening serum for subsequent treatments. 

As you can see, there’s not much of a difference between the two kits except that you get an adaptor cable. The Brilliant kit does come with more vials, though. So if you have a really bad case or if you want to have extras for future touch-ups, then you might as well get the premium package (though a 3-pack of the whitening gel is only $24. So if you’re really looking to save money and won’t use the adapter, then stick with the Lit kit). There’s also the option to pay out your Glo kit using Afterpay. This allows you to break up the payments into four interest-free payments of $49.75.

Glo also sells additional oral hygiene products, including toothbrushes, lip balm, and extra packs of the Glo whitening gel vials. The gel packs are useful because you’re going to need to repeat the treatment every six months or so. Packs range from $24 for 3 vials ($8 per vial) up to $65 for a 10-pack ($6.50 per vial). So, as usual, buying in bulk will save you, assuming you’ll use the gel. 

Glo shipping is free for all orders over $49. So if you are purchasing a kit, you’ll automatically get free shipping.

What You Get

When you order your first-time whitening kit, you’ll get:

• LED light whitening mouthpiece
• Storage case
• Whitening gel vials
• Lip care
• User manual

Depending on which kit you purchase, you’ll get an adaptor, travel case, lanyard, and 7 or 10 vials.

Guarantee

Glo has a 30-day money-back guarantee, but the company doesn’t have much in the way of details about that promise on the website. There is a manufacturer’s warranty for the device itself that’s good for one year. 

Customer Service

Glo has great customer service. The support team is happy to help, and you can reach them via phone, chat, or email. There’s also a good FAQ section, a blog with helpful articles, and video tutorials on the site. All in all, Glo does a good job of informing and supporting its customers.

Review by Katie P. on 8 May 2021

“Cool product, good for people with sensitive teeth i love this whitening kit. i used to use the crest white strips which worked well enough but hurt my teeth. glo works faster and better, and i don't experience any sensitivity. i will definitely keep using it, totally worth the investment.”

Review by Percy C. on 27 Jan 2020

“WOW!!!!Let me start with a short backstory. I have always been someone who was noticed and complimented for her smile growing up. Fast forward to 2 years ago when I had a terrible dentist put a very light crown on my "vampire tooth". When I looked in the mirror all I saw was this very white tooth and my slowly yellowing teeth. My teeth are sensitive and WOW!!!!I am a sceptic so I put off buying any 'at home" teeth whiteners. Then I decided to buy the GLO system. I CANNOT BELIEVE that my teeth match my super white crown now and I have only had GLO for a week! I am WAY more confident and truly grateful for a product that REALLY WORKS!!”

Review by Robert O. on 5 Jun 2020

“Incomparable customer support There was a glitch, and my order was not going to ship on time. As the order was a birthday gift, time was of the essence. Customer Support jumped in, expedited the order, and saved the day. Excellent service, prompt and clear communication. So uncommon with online stores. I'm hooked.”

Bottom Line

Glo has earned its positive reputation in the industry with good customer service, lots of helpful resources, and a solid product. The LED light and whitening serum combination make for a more productive whitening treatment, and results come quickly in most cases. Kits are affordable, and the monthly payment plans make it even easier to pay for these devices.
