A journalist who tested teeth whitening treatment in London has said that the procedure left her with a brighter smile.

Rebecca Cox, writing for Sky’s Showbiz page, had the treatment to see what effects it would have on her teeth.

She told readers that although she did not have particularly stained teeth prior to the procedure, she has been “proudly showing off my gnashers at any opportunity”.

Ms Cox said: “As a non-smoker with no taste for tea or coffee my teeth weren’t in need of drastic repair, but the whitening treatment has undoubtedly left my smile whiter and brighter.”

More people could be tempted to have teeth whitening treatment following the writer’s recommendations, especially after it was recently suggested that it is more effective than buying whitening toothpaste.

An oral health expert told NewsNet5.com that chemicals in toothpastes can often make teeth enamel look dull after continuous use.
