Fans will remember that Tony, who plays hairdresser Kenneth Du Beke, had a huge fight at the end of series five.
The resident Blow ’n’ Go expert faced a bitter rivalry with Sherrie’s hotel manager character Joyce Temple-Savage.
After a boozy night out, Kenneth’s key wouldn’t fit in the salon locks after Joyce had changed them.
She told Kenneth that she had shut it down because he was behind with his rent, but this prompted a disgusted Kenneth to attack Joyce.
When the pair finally came to blows, Joyce was seen to knock Kenneth’s teeth out beside the Solana swimming pool.
Fans were convinced the actor Tony had special dentures made, or a spot of clever CGI.
However, it turns out that Tony’s teeth being knocked out was the real deal.
Recalling their fight scene, 67-year-old Sherrie explained how she struggled to act her punching, accidentally hitting Tony too hard.
She said: “I remember Tony saying, ‘You’re actually doing it for real Sherrie. You’re actually thumping me in the face’.
“And I went, ‘I’m really sorry but I don’t know how to pull it’.”
The Loose Women star added: “I couldn’t help it because I really wanted to smack him because I thought, ‘It will look so much better if I smack him’.”
The scene ended with Kenneth’s front teeth flying out of his mouth covered in blood after a hefty smack from Joyce.
Tony, 50, said: “People always say, ‘How did they do that?’.
“Little secret… just before we filmed that scene, I’d had a fight with a patio door at my mum’s house.
“By the time I came to film I was halfway through having implant surgery to have my two teeth replaced. Derren phoned me up and said, ‘Do you mind if I write it into the show?’.
“I said, ‘Absolutely, let’s do it’. What you see me spitting out of my mouth is half a piece of chewing gum, very cleverly edited.”
Benidorm series 10 returns to ITV next week on Wednesday, February 28 at 9pm.
