Teeth whitening can add to a person's confidence, it has been claimed.
Owen Jones said procedures like Zoom teeth whitening will transform a person's teeth and could boost their self-esteem by making their overall appearance more attractive, when writing on the website UpdatedDailey.com.
"Sometimes, that smile becomes so contagious that you find yourself smiling and feeling better for the rest of the day on," he added.
Mr Jones also suggested a Hollywood smile can make someone appear friendly and more approachable to passing strangers.
He recommended coffee drinkers have teeth whitening as "the ingredients in caffeinated drinks can discolour your teeth", while smokers were also advised to undergo treatment.
People in the public eye whose teeth look beautiful and perfect are beneficiaries of teeth whitening work, according to Mr Jones.
With Zoom teeth whitening, patients can relax by watching a film while their teeth are lightened by up to eight different shades, the Irish Independent's Sinead Van Kampen said recently.
