Desire for a brighter smile is soaring across the UK, with online searches for teeth whitening hitting record levels. As the cost-of-living crisis continues, many are turning to social media for cheap and cheerful solutions, spawning a new trend known as 'Toothtok' – where dentistry tips and tricks are shared on TikTok.
However, a leading dental expert is now issuing a stark warning. Dr Anni Seaborne, head of general dentistry at Bupa Dental Care, states that while thousands of products promise a quick and easy white smile, most are ineffective and some can be actively harmful to your dental health.
The Toothtok Trends You Should Avoid
Dr Seaborne has taken on the role of myth-buster, analysing some of the most controversial tips circulating online. Her verdict on popular hacks might surprise you.
Charcoal toothpaste is a MYTH. While its abrasive nature can remove some surface stains, it will also wear down your tooth enamel if used repeatedly. This outer layer protects your teeth, and damaging it can lead to long-term problems.
Rubbing strawberries on your teeth is a MYTH. They contain malic acid, which can lift stains, but this same acid wears down enamel. Over time, this can make your teeth look more yellow as the yellowish dentin underneath becomes visible.
Oil pulling is a MYTH. Swishing oil around your mouth is a trend, but there is no solid scientific proof that it whitens teeth or removes toxins. It is not harmful, but it offers no proven dental benefits.
Baking soda is a MYTH. It might scrub off some surface stains, but it will not actually make your teeth whiter. Its abrasive quality means it can thin your enamel over time, again leading to a yellower appearance.
Lemon juice is a MYTH. Steer clear completely. It is highly acidic and can severely damage enamel, making teeth look yellower in the long run as the dentin shows through.
Purple shampoo is a MYTH. Do not put this in your mouth. While purple toothpaste exists, it acts as a visual trick and does not genuinely whiten teeth.
The Tricks That Can Actually Help
Amidst the sea of bad advice, Dr Seaborne confirms a couple of practices that can support your oral health and appearance.
Sipping water with wine is a TRY. This doesn't whiten teeth, but it helps rinse away tannins from wine and coffee that cling to enamel and cause surface staining.
Eating cheese is a TRY. Dairy is generally good for your teeth as it helps neutralise acids and supports enamel remineralisation. However, there is no proof it whitens teeth; it is tooth-friendly, not a whitening agent.
The clear message from dental professionals is to be highly sceptical of DIY whitening trends. For a safe and effective whitening treatment, always consult a qualified dentist.
