As a nation of coffee, tea, and wine lovers, many Brits are susceptible to stains that steal the natural white shine from our teeth. A confident smile can make all the difference.

If you're seeking to add some extra sparkle to your smile, consider Dr Dent's Crystal X Teeth Whitening Powder. A six-month supply is available for £9.99 on Amazon here.

Promising results within as little as seven days from a simple brushing routine, this minty fresh and sensitivity-friendly powder is a painless way to enhance your smile and boost your confidence. It's also peroxide-free, so it won't damage your tooth enamel.

Plus, all its ingredients are ethically sourced and cruelty-free. With over half a million satisfied customers, Dr Dent has earned a formidable reputation for brightening smiles nationwide.

Each product, including this whitening powder, comes with a satisfaction guarantee. To use it, simply dip your toothbrush into the powder, brush your teeth thoroughly for four minutes, then rinse with water, reports the Manchester Evening News.

If done twice weekly, you should see results soon. However, note that this isn't a substitute for toothpaste, so continue your regular dental routine.

The product has received a stellar average rating of five out of five on Amazon, with customers lauding its effectiveness. One pleased customer revealed: "After my first week of using the product I have started to notice a difference in the appearance of my teeth. They are beginning to appear whiter already. I think this product is working well and I am noticing a slight difference after each use," Another user remarked: "I've found the Dr. Dent whitening powder really good, used it in the lead up to a wedding. Used a few times a week along side my normal toothpaste and can see definite improvement. Leaves a nice taste and smooth feel to my teeth. Thanks! " A further glowing five-star review noted: "Works very well and leaves the mouth feeling clean and fresh."

At present, there is only one one-star rating for Dr Dent's Crystal X Teeth Whitening Powder on Amazon, but the customer opted not to leave a review.

Other options include MySweetSmile's teeth whitening strips priced at £24.99, or perhaps MySweetSmile's whitening powder for the same cost. The SmileTime Charcoal Teeth Whitening Powder from Boots is also available for £13.99.
