iSmile Teeth Whitening Kit with LED light

Teeth whitening, once a luxury reserved for Hollywood stars, has now become a sought-after beauty routine for many looking to boost their confidence and achieve that perfect, radiant smile. Various products promise to deliver that magazine-worthy smile, one of the standout options being the iSmile Teeth Whitening Kit.


The iSmile Teeth Whitening Kit, like other kits, functions primarily through the bleaching action of its main ingredient, often hydrogen peroxide or a derivative. This kit provides you with a gel that you place in trays, which you then fit over your teeth. An LED light, included in the package, accelerates the whitening process, breaking down the stains on the enamel surface.


While many venture into teeth whitening expecting instant results, it’s essential to manage expectations and understand the potential risks. Sensitivity, uneven whitening, and gum irritation are some side effects one might encounter. It’s crucial to educate oneself and possibly consult a dentist, especially if you already have underlying dental concerns.

Mia's Best - Thoughts on the iSmile Teeth Whitening Kit:

Diving into the iSmile Teeth Whitening Kit was quite an adventure, and here’s my take on it.


  1. First Impressions:
    • I finally gave in to the multitude of teeth whitening kit ads I kept seeing on Instagram.
    • I’ve always used teeth whitening strips, so I was eager to try out this kit, especially given its affordable price on Amazon.
    • When I unboxed it, I found a bunch of tools: three syringes, a mouth guard, and some instructions.

  2. The Application Process:
    • The kit promises several uses from the syringes. Though I stumbled a bit at the start, I got the hang of it eventually.
    • I appreciated the LED light’s ten-minute intervals, but I was a tad confused about the overall treatment duration.
    • One feature I really liked was the design of the mouth guard; it had a designated spot for the tongue, making the whole process more comfortable.

  3. The Results:
    • The kit touted noticeable results after just one use, and honestly, I did see a slight difference. I compared my teeth to the scale provided in the kit and noticed a subtle improvement.
    • However, I did spot some white marks on my teeth afterward, which left me wondering where they came from.

  4. Overall Feelings:
    • I was pleasantly surprised at how quickly I saw results, especially since it seemed faster than the usual whitening strips I use.
    • The lighting during my test made my teeth look even brighter, and I’m committed to using this product a bit more to see its full effect.
    • Considering the price, I’ve got to say I’m leaning towards being a fan.

So, my verdict? The iSmile Teeth Whitening Kit is a budget-friendly and seemingly effective method for teeth whitening. But as with everything, results may vary. It’s essential to be cautious and remember that a bright smile is just one part of overall dental health!

Most users report noticeable whitening within a few sessions, with some even seeing significant improvements after the first use. However, individual results may vary based on factors like starting tooth shade and adherence to instructions.

As with many teeth whitening products, some users may experience increased tooth sensitivity or gum irritation. It’s always recommended to follow the product’s instructions carefully and consult with a dentist if you have underlying dental concerns.

Teeth whitening products, including iSmile, primarily act on natural tooth enamel. This means that restorations such as crowns, fillings, or veneers might not whiten in the same way or at the same rate as natural teeth. It’s essential to consult a dentist to understand how whitening might affect your specific dental work.

While many see results within the first few uses, it’s crucial to follow the specific instructions provided with the kit. Overusing or leaving the product on for too long can increase the risk of sensitivity or other side effects.

Generally, it’s not recommended to use whitening products while having braces as the brackets cover parts of the teeth. Using a whitening kit might lead to uneven shading once the braces are removed. It’s best to wait until after orthodontic treatment or consult with your orthodontist before using a whitening kit.
