Those searching for a Hollywood smile like the kind sported by Tom Cruise ought to consider professional teeth whitening, it has been suggested.

Writing for the Irish Times, Fiona Reddan stated that this is currently one of the most popular treatments available for people struggling to rid their smile of coffee and nicotine stains, including who have already tried to do so with specialist toothpastes.

However, she noted that veneers, thin layers of porcelain that go over the front of a tooth, could be a good option for anyone after a pearly white look.

Ms Reddan said: “The number of veneers used will depend on each individual, it is generally recommended that the front eight are done on the upper and lower teeth to give the best effect.”

Recently, Dr Marty Marcus told Today’s Chicago Woman readers that many people have their teeth whitened in the summer in a bid to improve their appearance before big social gatherings.
