Luelli Teeth Whitening Kit: The Most Affordable LED Whitening? - Smile Prep (2024)

Luelli Teeth Whitening Kit at a Glance

Luelli first launched in 2020, aiming to fill the gaps in the oral care market. They saw that some affordable products didn’t get the job done, and some effective products were too expensive. Their goal was to create quality oral care solutions sold at affordable prices. As Luelli states: “We revolutionize products that really work better than anything else with reasonable prices compared to other brands.”

At the moment, they offer two complete teeth whitening kits, both with LED lights. They also sell their whitening gel on its own, which can work as a refill for their kits or on its own.

According to the company, you will see noticeable results after a single 10-minute session, and finish treatment in as little as seven days (if used once each day), or up to 14. If you use the lights, a built-in timer ensures you won’t over-whiten and damage your teeth.

You can purchase Luelli whitening kits directly from the company’s website or order them through third-party sites like Amazon. We suggest shopping around to get the best deal.

Pros & Cons of Luelli Teeth Whitening Kit

Luelli’s whitening kits are high-quality and effective, but no option is 100% perfect. Here are the biggest pros and cons of choosing Luelli.

Effectiveness

If a product can’t actually brighten your smile, things like price and comfort don’t really matter. Based on both company claims and customer reviews, Luelli seems to be pretty effective.

Luelli states that you’ll see initial results after a single ten-minute whitening session. You can whiten once per day for up to 14 days in a row (although the kit only has enough gel for nine uses), but the company says that most people need only 7–10. Most customer reviews seem to back these claims. Many people noticed a difference after their first application and wrapped up in seven days.

Since Luelli is a tray-based whitening system, it is more effective than options like pens, as it holds the gel in place against the teeth. And unlike strips, the tray will not slip out of place. Luelli’s gel uses 35% carbamide peroxide, which is less potent than hydrogen peroxide, but still effective.

Like nearly all whitening treatments — at-home or professional — Luelli works best on yellow stains. Brown, black, and purple stains rarely change much, if at all. Results last 6–12 months, depending on your habits. Luelli suggests you complete maintenance treatments about every 2–5 months and a full round of whitening every 6–9 months.

You can choose from two different LED lights. Luelli’s standard kit mouthpiece features 5 LED lights that strictly produce blue light, while their premium kit’s mouthpiece has 32 LED lights that can change modes to blue, red, or both, depending on if you want to whiten, sanitize, or both.

Affordability

Professional whitening can deliver significant changes to your smile in a single session. You walk into the office, then walk out about 1–2 hours later with a megawatt grin. But most people still choose to whiten at home — even if it takes longer to see results — because it’s cheaper.

Professional whitening is typically at least $400 per session and, depending on the system and dentist, could cost you over $1,000. Luelli won’t match in-office speed or power, but many people think the savings are worth it.

However, Luelli isn’t just priced lower than professional treatments; it’s more affordable than most other LED kits. Where some options cost roughly $200, Luelli’s standard kit is $39.99 and their premium option is $59.99. Usually, the company offers $10–$20 off this price when you purchase through their site, and you can get a discount code for your first order if you subscribe to their email list.

A good way to evaluate the value of a whitening system is to see how the cost breaks down per session. Luelli says their kits come with enough gel for nine whitening sessions. This means their standard kit costs $4.44 per session while their premium option is $6.66 per session. And since the lights are reusable and the company sells gel refill kits, you can reduce your costs over time. Their refill kits are $16.99 for nine treatments, or $1.88 per whitening session.

Quality of Ingredients

Effectiveness and affordability are important, but this is your smile we’re talking about — you need to know that your teeth will be safe, too. The core ingredient in Luelli’s whitening gel is carbamide peroxide. It works by oxidizing stain molecules and breaking them down, which both makes them less visible and allows them to be lifted out of the enamel.

Carbamide peroxide contains hydrogen peroxide but at a low concentration. For every 10% of carbamide peroxide, there is 3% hydrogen peroxide, making it a gentler whitening agent. The version they use has a 35% concentration, which has still proven effective for whitening.

Besides this active whitening agent, the Luelli’s formula contains:

• Carbopol: A polymer that thickens the gel, so it isn’t too watery.
• Propanediol: This helps keep the gel in liquid form and dissolves the other ingredients.
• Glycerine: This pulls moisture from the enamel, making it easier for the peroxide to work.

All these ingredients are common in oral care and beauty products. They are considered safe for humans when used properly.

Convenience

Whitening your smile comes with plenty of benefits — it can boost your confidence and even improve your mood. However, it can also complicate your schedule. You need to make time to complete your treatments, and even the easiest system will involve some prep and cleanup.

Luelli requires a small amount of prep; you’ll squirt the gel into the tray before placing it on your teeth. It’s not too hard, though it might take time to get the amount and placement perfect. Don’t be afraid to watch some video tutorials to master your technique. Cleanup just requires you to detach the tray, rinse it, and then put everything away.

Each standard Luelli whitening session is ten minutes (or you can use the premium kit for up to 16 minutes at a time). Because the light is battery-operated, you are free to do other things while wearing it — like cleaning the house, doing your morning routine, or even working. In total, Luelli should take about 15 minutes from prep to cleanup.

Because it uses trays and a light, it’s not as portable or inconspicuous as whitening strips or whitening pens. And since you have to prep the trays yourself, it’s not as easy as pre-filled trays. That means it’s difficult to take on the go, but since the sessions are short, that’s not a huge deal.

Comfort

Here’s an often-unstated truth: whitening your teeth is awkward. From weird flavors to bulky trays to cheek stretchers, there’s a lot that can make you uncomfortable. Fortunately, on the whole, Luelli is pretty comfortable to use.

They include a desensitizing gel in each of their kits and their refills. If you have sensitive teeth or start to develop zingers during treatment, you’ll just place this gel on your teeth after each whitening session. Use the tray to help it stay in place for 15–20 minutes so you can enjoy its full effects.

Since the gel is peroxide-based, it might have a slight chemical-like flavor. However, the tray should stop you from tasting it unless you apply too much. Plus, the gel has a slightly minty flavor, according to customers. There’s no mint-flavored ingredient listed on their website, but we’ll take buyers’ words for it. Some customers say this gel burns if you get it on your gums, so be careful when filling and applying your trays.

Some people also say it’s bulky, especially if you have a small mouth. When the light is attached, it can start to feel a little strenuous by the end of the whitening session. Still, most people find it bearable, and certainly not a deal breaker.

What Are Luelli Customers Saying?

Of course, you don’t need to take our word for it. Check out some customer testimonials below.

Final Thoughts

The Luelli LED whitening kit is effective at addressing yellow tooth stains in most individuals, using gentle ingredients paired with a desensitizing gel for comfort. If you choose either of their LED kits, we think you’ll be happy with your experience. Just remember that, like all at-home kits, there are certain types of stains it can’t change and the results aren’t as robust as in-office whitening.
