Best Teeth Whitening Kit? | Home Teeth Whitening With SmileTime

The Brand: SmileTime

SmileTime is a reputable and fast-growing oral cosmetics and home teeth whitening company based in the UK.

The brand has been featured in a number of large magazines and newspapers.

They were kind enough to reach out and offer to send me their LED Teeth Whitening Kit in exchange for an honest review, so here’s an account of my experience.

LED Teeth Whitening Kit

The kit comes in a sturdy, well-built box containing:

  • 3 Syringes of teeth whitening gel
  • An LED light
  • A mouth tray
  • An instruction card
  • A results chart / shade guide

It’s enough to last for 6 days.

Experience: What is Home Teeth Whitening Like?

I don’t doubt that brushing your teeth with charcoal powder first (which also has a whitening effect) would be beneficial, but I just brushed my teeth with my own regular bamboo toothbrush and my regular toothpaste. I did this before going to bed, so I wouldn’t consume any food or drink after treatment.

I treated my teeth for the maximum 30mins every night.

Because of the size and shape of the mouth piece, you can expect your mouth to get tired after around 15mins each time. It also generates a lot of saliva…

I think 15-20mins is more of a happy and comfortable medium, and if I did another round of treatments I definitely wouldn’t go for the full 30mins.

Overall, the process is very simple and the experience was not unpleasant.

The downside to this teeth whitening kit is the shape of the mouth piece:

Teeth Tray

Because the sides are not as high as the front, you can only really whiten the front portion of your teeth.

Results: Teeth Whitening Before and After

Considering how easy it was to use this product, I’m impressed with the results.

Anyone that knows me will know I hate my teeth, but SmileTime have helped reduce one insecurity.

It’s really hard to capture on camera, but on the shade guide I was a fairly consistent 10 at the front and around the sides BEFORE treatment:

And I finished around a 6 at the front:

If nothing else, my front teeth are noticeably brighter.
You can see the far left tooth is a much darker shade, where the tray didn’t reach.

What’s Next?

Once you finish the initial 6 day treatment, SmileTime offer a 1, 2 or 3 month subscription on their Teeth Whitening Gel Refills.

The refills only need to be used once every 1-2 weeks, so it’s super easy to maintain your pearly whites.

I definitely think the LED Teeth Whitening Kit needs to be supplemented with something like a charcoal teeth whitening powder in order to reach your side teeth too. I wouldn’t want to have sparkling white front teeth and yellow sides, but since I’m not at the sparkling white stage yet, I’m satisfied.

Considering how much I hate my teeth, SmileTime has truly made a difference to me and I’m extremely grateful to have had the opportunity to try this product.

I think the next step of my teeth whitening journey will be charcoal powder.


I would 100% recommend giving this product a try if you’re looking to get whiter teeth or even just brighten your front teeth slightly without breaking the bank.

All of this can be done in the comfort of your own home, with no disruption to your daily routine. No horrible dentists, no crazy costs.

    • It’s so easy to use and the results were surprising! I’d definitely recommend it if you don’t have super sensitive teeth and want a quick fix x

    • Compared to some other LED devices I’ve seen floating around, this definitely seems like one of the more solid choices. Would recommend if you don’t have major teeth sensitivity – let me know if you end up trying it, and thank you for reading!

  1. Wow, you can really see a difference in your teeth whiteness! However, the mouthpiece does look a bit intimidating. But I’d definitely like to try a teeth whitening kit for myself.

    • It’s a bit strange the first time, but you get used to it quickly! The results were definitely better than I expected, and if your teeth aren’t super sensitive I’d recommend this 🙂
