Extreme Sisters star Lucy DeCinque was left begging her dentist to take out her wisdom tooth, after twin sister Anna was forced to have an extraction due to infection.

But, with Anna getting her molar pulled out, the missing tooth meant they would no longer be completely identical, leaving Lucy pretty distraught.

‘If Anna takes out the tooth, I might have to take out my tooth here, a healthy molar,’ Lucy told her dentist.

However, he wasn’t having any of it, telling the camera that pulling out a healthy tooth for no reason crossed ethical boundaries.

‘A tooth for a tooth,’ the twins later went on to say.

‘That’s all we want, experiencing it together,’ the pair added, explaining to their boyfriend Ben Byrne why Lucy would be having her wisdom teeth removed, when it was Anna who had the infection.

‘If Lucy’s teeth are all healthy, no dentist is going to agree to pull out her teeth just so she can be identical to Anna, but it’s not realistic for Anna to live in pain, so they may be forced to compromise for once,’ Ben told the camera.

But that didn’t stop Anna and Lucy from trying.

This comes after Anna broke down in tears realising she would have to get a tooth removed and risk being unidentical to Lucy.

She said in a confessional: ‘Our main fear is what if our mouths are different and we’re not the same.’

She tearfully adds that she now knows that she’ll have to have her tooth taken out due to the pain, but this would mean the twins are no longer exactly identical.

‘I want to take it out, but I won’t without my sister.’

Cutting to the dentist’s point of view, he adds: ‘They’re quite emotional and particularly when they have an infection, pain and other things.

‘Once you spend time with them, and reassure them for a while, they usually comfort each other and that settles things down.’

Extreme Sisters airs on TLC in America on Mondays.
