Sandra Davis, 66, left a glowing review for the brand: “I feel a bit silly writing this, but it’s coming. I just wanted to leave a review as I think it’s extremely helpful for others to know what a difference this product can make. Of course, I understand that everyone is different and I certainly didn’t expect my teeth to miraculously look 20 years old.
“But what I can say is that they look better than they have in decades. At 66 and having lost my partner a few years ago, I had lost my confidence. This helped me get my spark back. It means more than words can say. From the bottom of my heart, thank you Smilie and Dr Tankard.”
Another customer commented as part of a longer review on the Smilie website: “Honestly I’m surprised. I expected them to lighten up slightly, but not like this.”
Additional reviewers shared their experiences: “The Smilie is much better than the more expensive brands. The button on the device took some getting used to, but otherwise seamless. Easy to use, no irritation and fast. I definitely saw results but not as much as I hoped. Still, a great solution to improving your teeth.”
As part of an extended review, another customer noted: “Very happy with how effectively this worked. I’ve always felt confident about my teeth, to the point where I really haven’t smiled in a photo since I was a kid…it was so easy and after six days, my teeth look much whiter, especially around the gums where they were very discolored.”
