Orthodontists in the UK have attacked the hit US TV show Ugly Betty for giving a "detrimental" portrayal of wire braces .
The makers of the series have come under fire for portraying the lead character, Betty Suarez, as 'ugly' because she wears train track braces .
There are also concerns as to why Betty - played by actress America Ferrera - is still wearing "heavy" braces in the third season of the show, which is shown on Channel 4.
According to dentists, ‘train track’ braces are very rarely prescribed to adults and even in cases where they are, they are not worn for more than two years.
Orthodontists are now worried the programme could discourage young viewers from seeking corrective dental treatment .
A spokeswoman for the British Orthodontic Society (BOS) said: "It is irresponsible of the programme makers to portray Betty as ‘ugly’ because she wears prominent braces ."
"Ugly Betty is in its third year on our TV screens and Betty remains in over-exaggerated, heavy train track braces ."
"This is not a true reflection of orthodontic practice. It is highly unlikely an adult would wear braces beyond two years."
She added: "Betty's braces are certainly intended to be seen by viewers as damaging to her appearance."
"People who wear braces are not ugly. People considering treatment should not be put off by such a stereotype."
"Many young people and adults see wearing braces as a rite of passage, and enjoy the transformation."
Dr Colin Wallis, a specialist orthodontist, commented: "It is completely inappropriate to associate braces with being 'ugly', just as glasses have previously been an object of ridicule."
He explained that braces for both adult and children patients "are considerably more discreet than what is being depicted in Ugly Betty".
"There are many adults in the UK now wearing braces that are either completely clear, or are placed behind the teeth, so you may not even know that your best friend is wearing them."
