Tooth whitening: is it safe?

Are home whitening kits causing more harm than good? Top celebrity dentist Dr Richard Marques talks us through the dangers of pursuing that DIY Hollywood smile

when traditional brushing and flossing doesn’t cut it, W it’s easy to head straight for a DIY whitening kit or race over to a beauty salon – but have you done your research? The products can contain harsh ingredients, so if they’re unregulated or used incorrectly you could end up with serious damage to your mouth and gums as well as those pearly whites.

THE RISKS

Dr Marques says: “Avoid buying products from anywhere other than a trusted pharmacy, as unregulated whitening kits can contain chemicals that are really unsafe and can cause damage and even tooth loss. Some contain acids and dangerous bleaches.”

THE ADVICE

“At-home whitening kits bought over the counter aren’t very effective, as regulations prevent any hard-working active ingredients being used to a level that will be noticeable. If you’re in need of a serious clean, I’d always recommend going to see your dentist – it’s the best way to ensure your teeth are in the best condition,” explains Dr Marques.

“Toothpastes and mouthwashes won’t work miracles, but they can help towards keeping your smile looking brighter. Avoid harsh peroxides when buying over the counter, and look for more natural ingredients for a gentle yet effective clean. Charcoal as an active ingredient is brilliant at cleaning stains and removing toxins, and using a whitening mouthwash regularly can make a real difference to the brightness of your teeth. Always read the instructions carefully before using any oral product, as some are designed to be used only occasionally.”
