Teeth whitening is something lots of us think about. A brighter smile feels fresh, confident – and let’s be honest – a bit more put-together. One common ingredient in whitening products is hydrogen peroxide. It’s effective, but it’s not without its drawbacks. So before you go all in, it’s worth knowing the facts.
How does hydrogen peroxide whiten teeth?
Hydrogen peroxide works by breaking down stains through oxidation. It penetrates the outer layer of your teeth and helps lift deeper discolouration – which is why it’s in so many whitening strips and kits.
But is it safe?
It can be, in the right hands. But overuse or incorrect application may lead to sensitivity, gum irritation, or damage to enamel – the protective layer that keeps your teeth strong and healthy. And once enamel is worn down, it doesn’t grow back. That’s why it’s always a good idea to speak to a dentist before starting any whitening routine.
Who should avoid it?
If you’ve got fillings, crowns, or veneers, hydrogen peroxide won’t whiten those areas – so results can be uneven. And if you’ve got gum issues or untreated cavities, it could make things worse. In short: not for everyone.
What about professional whitening?
If you’re after fast, noticeable results, a visit to the dentist is your safest bet. They can control the strength and application of hydrogen peroxide, keeping your enamel safe while getting your teeth brighter.
A gentler way to whiten
At Waken, we take a more thoughtful approach. Our Whitening Toothpaste and Whitening Mouthwash are formulated without hydrogen peroxide and instead use a combination of:
- Plant enzymes – including papain and bromelain, which help break down stain-causing proteins
- Pyrophosphates – to help reduce tartar build-up
- Sodium fluoride – to protect enamel and support remineralisation
In independent tests, Waken Whitening Toothpaste and Waken Whitening Mouthwash helped teeth appear up to 5 shades whiter when used twice a day for 2 weeks.
(Of course, results will vary – your teeth are as individual as you are.)
The bottom line
Hydrogen peroxide has its place, but it’s not for everyone. If you’re after a gentler, everyday way to look after your smile – without the risk – Waken’s whitening range is a bright idea.
Don’t just clean. Care.
