What is it?: It is a powder that you use in the same way as a toothpaste.
Cost: £29.99 for a year‘s supply (plus at the time I ordered I also got one free). By way of update (October 2021), it looks like they have upped their prices since I bought this to £30.99 plus postage and packaging, so you may want to shop around for the best price.
Does it work? Yes, but the results are not very dramatic
Would I buy it again? Yes, but I think it is best suited to maintaining whiteness after a whitening treatment.
Other options?: Loads and I keep seeing them pop up in my Facebook news feed since I bought Smirk teeth brightening powder Where to buy: I got it direct from Smirk but since they upped their price, you may prefer to go to somewhere like Amazon
I trialed Smirk teeth brightening powder by using it every 3 days for 2-4 minutes in accordance with the pack instructions (which says to use it 2-3 times a week). I have been using this for about 6 weeks now.
It is a blue-purple coloured powder that you dip your toothbrush in and then brush your teeth as if using regular toothpaste.
Using Smirk teeth brightening powder does create a kind of froth (not as much as normal toothpaste) and it stops frothing at about the 3 and 1/2 minute mark.
It says that it is mint flavoured, but I would describe it more as tasting like over the counter cough sweets that you get in newsagents and corner shops with a hint of mint. If I am being honest, after prolonged use, the flavour of this started to make me feel a bit ill.
Smirk teeth brightening powder did whiten my teeth over time, but the results were not dramatic.
I would say this product is probably best suited to maintaining whiteness after using a more dramatic whitening product or treatment.
That said, you do get a lot of product for your money so it can be used across the whole year in this maintenance kind of way and it comes in a plastic tub with a flip top lock lid which means it it protected from moisture caused by steam in the bathroom.
