DiamondSmile Review: A Reliable LED Teeth Whitening Kit

Strains on the teeth are inevitable consequences of our daily habits and lifestyles, primarily due to the consumption of deeply pigmented foods and beverages such as coffee, tea, red wine, and certain fruits, along with the use of tobacco products.

Over time, these substances can lead to a spectrum of discoloration, ranging from subtle yellowing to more pronounced and stubborn stains on the enamel of our teeth. Stains or yellowing teeth can impact our first impressions when we smile at someone, whether known or unknown.

I, too, experienced discoloration of my teeth, and it made me feel hesitant to smile or engage in conversations with friends or colleagues. After searching for a reliable solution, I came across the DiamondSmile oral whitening device. Its fast Blue LED therapy immediately caught my eye, and the price is reasonable.

Moreover, the features and benefits it offers are incomparable. I've been using this mouthpiece for almost two months now and will share my experience in this DiamondSmile review. Let’s dive in and explore everything about this innovative device with me.

There is much more to learn about this device. Let's jump into this DiamondSmile review and explore how it works its features, and the benefits you will get from using it.

How Does It Work?

After delving into extensive research, I've uncovered the functional magic behind the DiamondSmile teeth-whitening mouthpiece. Let's break it down:

The DiamondSmile harnesses the power of innovative LED (Blue) light technology, a familiar innovation you've likely encountered. But have you ever considered its therapeutic wonders?

The beauty of LED technology lies in its lightweight design, which makes the mouthpiece the epitome of portability and convenience. Simply put, it's as easy to carry as it is to use.

But wait, there's more! Inside the kit, there are 10 vials with 10 milliliters of Whitening Gel. These are not like your regular toothpaste, but these ten whitening paste gels are used to transcend surface stains.

Moreover, packed with low concentrations of hydrogen peroxide, carbamide peroxide, and peroxide of urea. These heavy hitters dive deep into your teeth, unveiling their natural luster.

In a nutshell, DiamondSmile isn't just a teeth whitening kit; it's a sleek and portable powerhouse harnessing the brilliance of LED light technology for a lasting, radiant smile.

Key Features of DiamondSmile

The DiamondSmile oral whitening mouthpiece is packed with many outstanding features that set it apart from other in-home devices. Here, I will demonstrate all the features I have experienced with this innovative device:

Key Features of DiamondSmile

Compact Design

The most excellent feature of DiamondSmile is its compact structure. It is easy to carry and use anywhere. Also, it has an elegant look and is designed to be compatible with Android and iPhone smartphones.

Blue LED Technology

DiamondSmile utilizes blue LEDs, an innovative technology. The tray contains 16 blue LEDs, and each of them has lightweight halogens to eliminate strong stains from teeth. These halogens generate heat over time, but their impressive cooling capability prevents overheating.

This powerful Cold Blue LED light produces 460 to 480 nm of wavelength, which is more than enough to penetrate the hard layer over the enamel.

High-quality Mouth Tray

The mouth tray is crafted with soft TPE silicone material. The mouth tray is waterproof and highly flexible to fit in your mouth appropriately. The TPE silicone material is durable and lasts a long time.

Energy Saving

Another outstanding feature of DiamondSmile is that it doesn't need an energy source or battery to operate. The tray has an in-built USB cord to connect to a mobile device. The connection smartphone charges the tray and prepares to work for a good time.


There is a timer built into the square-shaped power switch that is connected to the tray and is mainly used to start the device. By default, the timer is set to 16 minutes and will turn off the tray after the given time. It is actually the working period that DiamondSmile needs to whiten our teeth.

White Gel

In every DiamondSmile packet, you will get three White Paste Vials. This paste is used over the teeth before inserting the tray. Moreover, it is not any ordinary toothpaste but contains hydrogen peroxide, carbamide peroxide, and peroxide of urea that are highly effective in removing tooth strains and work properly with the blue LED.

These are the advanced features I have observed while using DiamondSmile, which make this device an excellent choice for those who want to remove the yellowness of their teeth effectively.

Benefits You Will Get From DiamondSmile

Until now, I have highlighted the features of this amazing teeth-whitening mouthpiece in this DiamondSmile review. But what about the benefits?

After incorporating the DiamondSmile, the mouthpiece offers a range of benefits that are fair enough to put it at the top. Let's see the benefits below that you will get from DiamondSmile:

Benefits You Will Get From DiamondSmile


The lightweight and compact design of DiamondSmile allows you to take it with you on the go. Simply put the mouthpiece in the box it comes in and pack it in your bag.

Works Fast

I have tried many oral therapies so far, and most of those were time-consuming. But I was astonished by DiamondSmile's fast workability. In each session, it only works for 16 minutes, but the outcome is unpredictable. You will notice that your teeth are shinier and whiter than before.


Can you imagine any dental treatment without pain? I can't. It is because I have previous experience with various oral treatments such as crowns, root canals, washing, etc. I still remember all those terrible, painful therapies.

However, DiamondSmile is like a dream device to me. There is no pain, but it works best to remove the stains from my teeth.

Safe to Use

For me, the primary objective was always safety. The DiamondSmile meets my priorities as it is a chemical-free oral care device. The gel used for layering over the teeth before inserting the LED therapy also contains beneficial elements.

Money Saving

Nothing is more satisfying than having an often-used device that doesn't require any energy or batteries and saves you money over time. The DiamondSmile works by connecting the USB port to your smartphone and nothing else.

Easy Maintenance

DiamondSmile doesn't need much maintenance, although you just have to wash the mouth tray after each use. The tray is made with waterproof material, which makes it easy to wash and keep clean forever.

The benefits of DiamondSmile impressed me more, and now I don't feel shy about talking to anyone or smiling anytime. Within two weeks, I had whiter teeth and a brighter smile.
