A man who described his teeth as 'badly stained' from years of drinking coffee has noticed a 'huge difference' after trying whitening strips that cost around 83p per day. The HeySmile Teeth Whitening Strips, now available for £19.99 on Amazon, are designed to deliver visible whitening after just one application.
According to independent laboratory testing, the HeySmile whitening gel showed strong performance over multiple applications. In a controlled study, stained enamel samples were whitened by an average of 10 VITA Bleachedguide shades after six uses, a recognised global measurement for tooth whitening. The same testing found HeySmile's gel to be more effective than a comparable whitening gel under the same conditions.
The brand uses a PAP-based whitening formula, developed as an alternative to peroxide, focusing on effectiveness while being gentle on teeth and gums. The strips aim to break down stains from coffee, tea and smoking, while avoiding common side effects like tooth sensitivity or gum irritation. They are vegan-friendly and cruelty-free.
On Amazon, the product has a rating of 3.9 out of 5 stars. One reviewer, Kevin, said: 'OMG these strips are amazing. I was sceptical but gave them a go anyway. Smoker and coffee drinker, my teeth were badly stained. The first strip was used today and I can see a huge difference straight away.' Another user commented: 'Really happy with these strips! Easy to use, no sensitivity at all, and I noticed my teeth getting whiter after just a few applications.'
For alternative options, Smile Therapy offers Advanced Teeth Whitening & Cleaning Strips reduced from £39.99 to £17.99, targeting surface-level stains. Boots also stocks Wisdom Intense White Teeth Whitening Strips Express for £18, promising results in three days.
