Who is SmileTime?

SmileTime is a teeth-whitening brand created in 2019 by Natalie Quail, an ex-international tax lawyer. The company is backed by 30 years of dental expertise through its partnership with UK dental chain Smileright.

The company has grown rapidly since its inception. It is now the fastest-growing and most recognisable premium oral cosmetics and at-home teeth whitening brand based in the United Kingdom.

In 2019, the company was featured on BBC One's Dragons' Den, where they were able to secure investment from Touker Suleyman & Steven Bartlett in front of 2 million viewers.

They have also been successful with their products at nationwide UK pharmacy Boots, the Queen's pharmacy in Marylebone, London and John Bell and Croyden.

What is the SmileTime Teeth Whitening Kit?

SmileTime is a teeth whitening kit that uses a special formula that's been proven to work. It's safe, gentle and affordable, and it only takes 15 minutes for you to get whiter teeth!

The SmileTime Teeth Whitening Kit includes everything you need to make your smile brighter in just 15 minutes: a tray for applying the gel to your teeth, a mouthpiece with blue light, and the special formula itself.

SmileTime's Teeth Whitening Kit has everything you need to brighten up your smile

The gel contains an advanced active whitening ingredient called PAP, which activates when exposed to blue light. This combination of ingredients helps your teeth become whiter without any sensitivity or pain.

With SmileTime, you'll see results in as little as 15 minutes—and they'll last all day long!

What's in the box?

Although we briefly mentioned what's included in the SmileTime Whitening Kit, the following list is a breakdown of what you get in the box:

  • 6 x Applications of Teeth Whitening Gel
  • 1 x Mouth Tray
  • 1 x LED Light
  • 1 x Instruction Card
  • 1 x Results Chart

What is the SmileTime Premium Teeth Whitening Kit?

If you're looking for a stronger, faster way to brighten your smile, SmileTime also offers a Premium Teeth Whitening Kit. While this whitening kit is very similar, it includes a stronger version of SmileTime's advanced PAP formula that whitens teeth without any pain or sensitivity during or after treatment.

This whitening formula can whiten teeth up to 10 shades of whiter, over a course of 3-6 days. Most customers are able to see a visible difference of up to 2 shades after the first use.

This kit costs a little more, but if you are looking for faster results it might be the right fit for you.

What makes SmileTime different from other teeth whitening kits?

This vegan teeth whitening kit formula includes PAP which is a known active teeth whitening agent that's able to whiten teeth efficiently without causing sensitivity. Unlike many affordable teeth whitening brands on the market today, this brand is UK-approved as well as vegan!

PAP whitening formulas have been scientifically proven to whiten and brighten teeth after a few uses as shown in the clinical trial study by the Journal of Applied Oral Science.

SmileTime's whitening formula helps prevent gum irritation, tooth sensitivity and other side effects often caused by teeth whitening kits that contain hydrogen peroxide.

How do you use the SmileTime Teeth Whitening Kit?

You can use SmileTime's Whitening Kit in the comfort of your own home, and it's easy to do! Just follow these steps:

  1. Brush your teeth.
  2. Attach the LED light to the mouthpiece.
  3. Apply the whitening gel to the top and bottom sides of the mouthpiece.
  4. Put the mouthpiece in your mouth and leave for 15 minutes.
  5. When the 15 minutes is up, take out the mouthpiece and spit any residue out and rinse your mouth with water.
  6. Repeat the process every day for 6 days to get the best results.

SmileTime recommends that you use its Bamboo Toothbrush and Charcoal Whitening Powder to brush your teeth before using the kit.

The following video shows you how to use the SmileTime Teeth Whitening Kit step by step:

Is SmileTime safe for my teeth?

Yes. The SmileTime tooth whitening kit is completely safe to use on your teeth, gums, and enamel. It will not damage any of these things while it improves their appearance.

If you have particularly sensitive teeth or are worried about them getting damaged, don't be! The formula has been tested extensively to ensure its safety on all types of teeth and gums.

Will you have sensitive teeth afterwards?

No, you shouldn’t have sensitive teeth after whitening using the SmileTime Whitening Kit. However, some people may experience a little teeth sensitivity after their first use of the kit. This usually goes away within a few days.

If for some reason your teeth sensitivity does not go away, it's best to visit your dentist and make sure that you don't have any underlying dental issues that need to be addressed.

Smile Avenue Whitening Kit

Smile Avenue

For an alternative whitening kit to SmileTime that is easy to use at home (and at an affordable price) and will give you natural-looking results, check out Smile Avenue's teeth whitening kit.

This teeth whitening kit from Smile Avenue has already earned a good reputation in France and is now gaining popularity in the UK.

The whitening gel in Smile Avenue's teeth-whitening kit includes the main active ingredient PAP, an ingredient similar to that used in SmileTime products.

Unlike hydrogen peroxide, which is a harsher ingredient commonly used for teeth whitening by dentists, PAP is gentler and causes less sensitivity in your teeth after you've finished using the product. Another ingredient included in this whitening gel is hydroxyapatite, which remineralises your teeth and strengthens enamel.

Snow whitening kit

Snow's whitening kit is a safe and effective teeth whitening alternative that uses proven ingredients like hydrogen peroxide and carbamide peroxide. They have two different whitening kits available, their Original Whitening Kit and their Wireless Whitening Kit. Both use Snow's safe whitening serum, which includes the following ingredients:

smiletime teeth whitening reviews
Snow Original Whitening Kit
  • Hydrogen peroxide
  • Carbamide peroxide
  • Glycerol
  • Deionized water
  • Sodium bicarbonate
  • Carbomer
  • Potassium nitrate
  • Peppermint oil

The first thing you'll notice about this alternative is that it comes from the United States. If you're ordering from the UK, you'll need to allow for extra shipping costs and time when ordering from the UK (or anywhere else in the world).

The kit comes with everything you need to get started and uses LED technology to help you get that pearly white smile you've always wanted.
