Home Teeth Whitening Can Damage Healthy Teeth

Mon, 15 Nov 2010

People who use home teeth whitening treatments run the risk of causing permanent damage to their teeth and gums, dental experts have warned.

A growing number of websites are promoting potentially harmful at-home whitening techniques, including brushing teeth with soap, salt, baking soda and even the bleach hydrogen peroxide.

However, dentists claim that such DIY treatments can destroy the enamel of the teeth, making them look darker rather than whiter, and also cause lasting damage to gums . They also warn that most online whitening recipes are often recommended by people with no dental training.

But despite the potential dangers, home teeth whitening techniques are becoming increasingly popular, especially among teenage girls who want a Hollywood smile but can’t afford the cost of professional treatment.

Professor Andrew Eder, clinical director of the London Tooth Wear Centre, said: "There seems to be a growing concern among teens about their teeth, and the internet offers many whitening recipes. Some of these have the potential to damage healthy teeth ."

"Household baking soda is an abrasive, so that with repeated use the white enamel may be worn away and leave teeth browner and with increased sensitivity. Salt crystals will scratch the enamel. Any treatment involving acid is particularly harmful."

Dr Stuart Johnston of the British Dental Association added: "The hard tissue of the teeth requires strong chemicals to whiten it that are only safe for use by properly trained clinicians."

"Trying to use recipes for whitening from the internet really isn't a good idea and could lead to individuals damaging their teeth and causing themselves pain."

'It could also cost them money, because having problems repaired by a dentist after attempts at self-whitening could cost many times what would have been paid for a proper, professional treatment by a dentist in the first place."
