Smile Guru Arvostelua 25

The product really gives a good whiteness to the teeth. This is not permanent, but lasts a few days. It lifts the whiteness of teeth by three or four degrees. Easy to use!

Sadly disappointing with this product. Strips often just breaking up on application. Using 2 times a day not always convenient. Even though a great idea of them just dissolving in the mouth. Not notices any difference as yet after a week. Have wasted quite a few strips with them breaking up.

They are fairly easy to apply-ensure your teeth are wet and fingers are dry. This is my second round of using them and noticed a slight colour difference, I wouldn't say enough that others would notice.

Did lighten my teeth and was easy to use so initially was pleased. However, the sensitivity it caused soon after the application was horrendous. I had to buy expensive specialist sensitivity toothpaste and it's taken nearly two weeks for them to feel better. Personally, it's not really worth it. Disappointing.

Excellent whitening strips. I have tried a few before these with no effect. But these smile guru one's are very effective. Make sure your hands are dry with you apply them. Would definitely recommend to anyone and will buy again

Delivery was prompt.
Saw the difference immediately but unfortunately did cause sensitivity.

Didn’t want to whiten my teeth with conventional whitening trays and bleach as my teeth are quite sensitive.
Thought would try these whitening strips and have been really happy.
Did a two week course and now just use the strips every 2 days or so.
Have noticed they look a couple of shades lighter feel shiny and love the minty taste after using .

These definitely do have a whitening effect on your teeth. Perfect for applying before you go out. I recommend you try for yourself and follow the instructions closely. They work!

I have very yellowish teeth due to lots of coffee and I very fussy about my teeth though I try them out I tend use More in evening my teeth looking amazing ! I do every other day x

It's not easy to fit it on the bottom teeth, not noticed a change yet, only been a week though

Great product just a little bit fiddly to get on till you master it, but the video provided for thar was fantastic.

Brilliant product once you get used to putting them on.
will 100% buy again

The speed in which they came was fantastic but I can't really get the hang of using the strips. They break every time I try and stick them to my teeth and I am following the limited instructions given. I have given up now, so i feel my purchase was just a waste of money unfortunately :(

I received product really quickly.. The strips are very fidley to apply and sticks to fingers... I haven't noticed any difference yet, but still using product..

I’m currently at day 10 of 14 and I think I can notice a difference. I found the strips easy to apply to the top teeth but found the lower ones a lot trickier. However, I DM’d the Singing Dentist on Instagram and he very kindly did a video demo for me and also left me some audio instructions - so a shout out to him for doing that for me.

Love this product ! So easy to use and i love how the strip just absorbs itself !
5 stars for sure :)

I am now into day 4 of whitening strips and can already see amazing results. I drink alot of coffee and red wine and these really do remove stain left behind.
Super easy to apply and leaves mouth feeling so fresh.

I've been using the whitening strips for a few days and I'm excited to see the end results
