"The peroxide solutions basically bleach or whiten the enamel, which is the outer covering of the tooth, and the dentine, which is the inside of the tooth. When both the enamel and dentine are bleached or whitened you get a much improved colour of the teeth that is usually sustained well for the long term," he says.

How long will it take to whiten my teeth?

According to Dr Swan, the time it takes differs depending on the result that you want. "The in-clinic appointment for laser whitening often takes around an hour, but you’ll need to wear your whitening trays for 30 minutes a day, for anywhere between three and 14 days after your appointment, depending on how white you’d like your teeth to be. For a naturally white smile, three days is sufficient.”

How we tested teeth whitening kits

Over the years, the GLAMOUR team has collectively tested dozens of teeth whitening products and kits, having also reviewed them on sensitive teeth with a weaker enamel. When judging each option, we've considered its value for money, efficacy (how well they brighten the teeth) as well as strength (whether they resulted in any abnormal sensitivity or uncomfortable feel) and how intuitive they are in use (especially if the reviewer is new to teeth whitening).
