If there is one thing social media has taught us, it’s that there is a trend for absolutely everything and dentistry is no exception.
From DIY teeth whitening hacks to ultra-white veneers and “natural” toothpaste alternatives, our feeds are full of dental care trends and people promising the perfect smile in a matter of days.
But just because something is trending doesn’t mean it’s good for your teeth.
There are a few dental trends we’re more than happy to leave behind.
These are the ones we’re saying goodbye to in 2026.
1. DIY teeth whitening
Lemon juice. Baking soda. Charcoal. Whitening hacks involving ingredients you probably already have in your kitchen. We’ve seen them all.
The problem with this popular dental trend? Your teeth aren’t and should never be a DIY project.
Many at-home whitening hacks rely on highly acidic or abrasive ingredients that can damage enamel and irritate your gums. Whilst some methods may temporarily remove surface staining, that doesn’t necessarily mean they’re actually whitening the tooth.
If you’re looking to brighten your smile, professional teeth whitening is a much safer and more predictable option. In the UK, the NHS recommends having whitening carried out through a dental professional, who can assess whether whitening is suitable for you and help protect your teeth and gums during treatment.
Our verdict: Leave the kitchen ingredients in the kitchen.
2. Charcoal toothpaste as a miracle whitener
Charcoal toothpaste has had a serious moment on social media, often marketed as a natural way to achieve a brighter smile.
But charcoal isn’t a magic whitening ingredient.
It may help remove some surface staining because of its abrasive properties, but it doesn’t change the natural colour of your teeth in the way professional whitening can. There are also concerns around excessive abrasion, particularly with prolonged or aggressive brushing.
Perhaps most importantly, don’t sacrifice effective everyday dental care in pursuit of a whiter smile. A good oral hygiene routine should be about protecting your teeth, not just making them look whiter.
Our verdict: Your toothpaste doesn’t need to be black to make your smile brighter, a good oral hygiene routine needs to be your priority.
3. The ‘bigger is better’ veneer look
There was a time when the ultimate smile meant extremely white, perfectly uniform and noticeably large teeth.
Thankfully, we’re moving towards something much more natural.
Modern cosmetic dentistry is increasingly about enhancing your smile while maintaining your individual features. The goal shouldn’t be for everyone to have the same set of teeth, it should be for your smile to look healthy, balanced and right for you.
Veneers and other cosmetic treatments can create beautiful results when carefully planned, but they’re not something to choose simply because you’ve seen a dental trend online.
Our verdict: Natural-looking smiles are always in.
4. Copying someone else’s smile
Your favourite celebrity’s smile might look incredible, but that doesn’t mean it’s the right smile for you.
The shape of your face, your natural tooth proportions, your bite and your existing teeth all play a role in creating a smile that suits you.
Rather than bringing a photograph and asking for an exact copy, cosmetic dentistry should start with understanding your smile and what you’d like to change.
The best cosmetic dentistry is often the kind where people notice that you look fantastic, but can’t quite work out why.
Our verdict: Inspiration? Absolutely. Copy and paste? Not so much.
5. TikTok dentistry
We’re not anti-TikTok. In fact, social media can be a brilliant way to make dental information more accessible.
The problem comes when a 30-second video completely replaces professional advice.
Dental problems aren’t one-size-fits-all. What worked for someone online may be completely inappropriate for someone else and some viral “hacks” or popular dental trends can cause genuine damage.
Before trying a new dental trend, ask yourself one simple question:
Would I be happy for my dentist to know I was doing this?
If the answer is no, that’s probably your sign to put the toothpaste down.
Our verdict: Follow your dentist advice and if you have questions or want to try something new book an appointment.
6. Treating your smile like a trend
Perhaps the biggest dental trend we’d like to leave behind is the idea that there’s one definition of a perfect smile.
Teeth don’t need to be completely identical. They don’t need to be unnaturally white. And you don’t need to change something simply because you’ve seen someone else change it.
A healthy smile should be the priority. Cosmetic dentistry can then be used to enhance the things you’re already happy with, rather than making you feel as though you need to completely redesign your appearance.
So, what is worth keeping in 2026?
At our practice in Kensington, we’re much more interested in dental trends that actually benefit your oral health.
Think:
- Regular dental check-ups
- Professional dental hygiene
- Evidence-based teeth whitening
- Preventative dentistry
- Good brushing and interdental cleaning habits
- Personalised cosmetic dentistry
- Looking after your gums as well as your teeth
- Asking your dentist before trying something you’ve seen online
The best dental trend isn’t a new hack, product or treatment.
It’s looking after the teeth you already have.
And that’s one trend we hope never goes out of fashion.
