Smile Avenue teeth whitening kit reviews and features
Below we explain what makes this our choice for the best teeth whitening kit of 2019.
Kit contents ★★★★★ (5/5 stars)
Smile Avenue’s teeth whitening kit contains everything you need for a professional whitening experience at home:
3 x 10ml syringes of whitening gel
- 17 ml pre-treatment cleaning spray
- A fixed-shape mouth tray
- LED light to accelerate whitening results
- A shade guide so you can check your progress
Many kits on the market only contain 10ml or 20ml of gel, whereas this kit’s generous allowance means you might have some left over to top up your results at a later date (depending on how long your initial treatment takes).
The cleaning spray is another bonus item not found in many other kits. Using this before applying the gel helps remove surface stains so the gel can get straight to work whitening the teeth themselves.
Ingredients ★★★★☆ (4/5 stars)
When you’re comparing teeth whitening kits, it’s important to check the ingredients used in the gel and the country of origin. A poorly formulated gel can cause tooth sensitivity and gum irritation. Some gels are produced in countries which have sub-standard quality control and regulations in place, but Smile Avenue’s kit is manufactured in the US and conforms to EU regulations for cosmetic products.
Here is the ingredient list for the whitening gel: Glycerin, Propylene Glycol, Carbomer, Mentha Piperita oil, Triethanolamine, Mica, Sodium Carbonate Peroxide, Aqua, Sucralose, Limonene
The active ingredient, sodium carbonate peroxide, is a gentler alternative to hydrogen peroxide. Hydrogen peroxide is the main ingredient used by dentists for professional whitening, but it often causes tooth sensitivity. We didn’t experience any pain or burning sensation when using this kit.
It’s reassuring to know Smile Avenue’s gel has been formulated to maximise results without harming enamel and gums.
Ease of use ★★★★★ (5/5 stars)
We would give this six stars if we could, because it’s so easy to use. Some whitening kits come with a thermoforming mouth tray, which you have to place in boiling water and then mould to the shape of your teeth before using it. With this kit, the one-size-fits-all mouth tray is ready to use straight away.
There are four simple steps to use this product:
“Application quite simple by following the instructions as indicated on the box. Good value for money when compared to the dentist!”
The fact that the LED light attaches directly to the mouth tray means you have your hands free to get on with anything you like during the 20-30 minute application. It’s so easy to fit this into your normal day. We found it best to use after eating and brushing our teeth at night, so we didn’t eat or drink anything after the whitening.
You should continue using the kit for 10-14 days. There is enough gel for 15 applications, so if you have some left over, you can keep it to ‘top up’ your white smile another time.
Results ★★★★★ (5/5 stars)
We only had to use this kit for a few days to see noticeable results, which was a nice surprise! Using the shade guide included with the kit, we measured 3 shades of whitening by the end of the treatment.
It’s effective at removing stains from yellow teeth from things like tea, coffee and tobacco. Many reviewers on Amazon.fr mention similar delight with their quick results:
“I hesitated before investing in this type of product but I am not disappointed with the result. As a former smoker, I noticed a slight yellowing on my teeth that concerned me. I have not completed the recommended 14 days of treatment yet but I already feel that the improvement is visible.”
“Just 20 minutes a day and already after 4 days I saw a difference. My teeth are whiter, brighter. Thank you for the simplicity of use and especially the effectiveness of the product much cheaper than a whitening session at the dentist.”

Alternatives to this kit
For a kit at a slightly lower price, we recommend this kit offered by Very Good Smile. It provides similar results, but the kit only contains 10ml of whitening gel (with a different formula) and doesn’t come with the pre-treatment cleaning fluid, so it’s not such good value overall.
Read our separate review of Very Good Smile whitening kit to find out why it’s another of our top recommendations for teeth whitening kits in the UK for 2019.
Smile Avenue teeth whitening kit is our top pick for 2019 because it gives great results for an affordable price but, more importantly, it comes with the reassurance of high-quality, strictly regulated ingredients. The generous 30ml of whitening gel and the extra cleaning solution are just the icing on the cake!
You can buy this kit with complete peace of mind, because it comes with a 100% money back guarantee if you’re not satisfied. Plus, Smile Avenue’s customer service team is on hand to answer any questions you have or help with any issues.
