As with so many things worth enjoying in this life, Christmas can be very bad for your teeth. If you’ve been downing espressos to keep you going after your fifth party of the week, or you knocked back a few glasses of red to make your cousin’s partner more tolerable, your teeth may well have lost a bit of its shine over the festive period.

Thankfully you can easily restore them at a great price thanks to the Boxing Day sale at MySweetSmile, with 20% off individual products and 30% off bundles. The sale runs from 8am on Boxing Day to 4pm on New Year’s Eve, so be sure to act fast if you’re in the market for a refreshed smile. Along with discounts on products, there’s also a buy two get one free offer, as well as buy one get another half price.

Highlights include the MySweetSmile toothpaste, usually priced at £12.49. This one promises a very minty sensation alongside all the plaque and tartar-battling ingredients you’d expect. Strawberry and mango flavours are also available, if you’re feeling adventurous.

So what of the whitening products? The whiten and strengthen bundle is a great choice for anyone with a need for brighter teeth and less sensitivity, usually retailing at £49.98 but is now £34.99. Inside you’ll find MySweetSmile’s whitening powder, which is applied like toothpaste, and the enamel care serum – which not only strengthens the enamel, but is said to reduce sensitivity too.

For spot jobs and tricky crevices that the other treatments might not have reached, the teeth whitening pen, usually £19.99 but is now £15.99, will clear up any stragglers. There’s also the ultimate bundle, featuring MySweetSmile’s whitening strips and its whitening powder, that should cover all bases and usually sells for £49.98 but is now £34.99.

With more than 5,000 Amazon reviews, the whitening powder – which is included in the whiten and strengthen bundle – currently has a 3.8 out of 5 average rating. “This teeth whitener is really good, it does take a week or two to show results but my teeth look a lot whiter and feel really clean, it’s tastes nice and hasn’t made them sensitive either. Highly recommended,” said one five-star review.

“I had noticed some staining on my teeth so thought I’d give this a try,” said another five-star appraisal. “This stuff is really really good, my stains were almost gone after just one use with an electric toothbrush.” Another added: “After drinking shed loads of coffee daily, my husband’s teeth had long forgotten what white looked like! After just one usage, the sparkle was back.”

Some customers have struggled to see a difference, however. “I’ve had it a few weeks now and used it every day alongside my other half and there hasn’t been a difference at all,” said one review. Another person said: “Having tried a lot of products that say they remove stains from your teeth. At last a product that really works . After using for a short while, have noticed a definite. Improvement in my teeth, and have been noticed by a friend , who asked what I was using. Would give this product a 100%.”

If you’re interested in alternatives, the Superdrug ProCare Dissolvable Teeth Whitening Strips are £11.99, and Hismile’s PAP+ Whitening Strips are available for just £19 per pack.
