The notoriously potty-mouthed chef was playing the game Read My Lips, in which he had to guess what viewers were shouting at him via video link while wearing noise-cancelling headphones, when he made the remark.
As one contestant repeatedly shouted the word ‘garlic bread’ at him as he attempted to guess the dish, the TV star said he couldn’t understand what she was saying to him because of the ‘gap’ in her teeth.
The virtual audience booed Ramsay after his comment, and one fan said they were so disgusted they had to turn off the TV.

Viewers took to Twitter to share their frustration after Ramsay’s guest appearance.
One fan said: “I cant believe Gordon Ramsay just insulted that lady’s teeth live on TV.
“Am so disgusted I’ve switched it off!
“Ant and Dec laughing and didn’t say anything! Well done what a fantastic example you all are!!”
Whilst another added:”A gap in your teeth doesn’t affect your speech.”
A third said:”No way did Gordon Ramsay just say on live TV ‘it’s the gap in her teeth I can’t understand her.”
Another commented: “I really usually like Gordon but he shouldn’t of insulted that lady about her teeth, she was very happy to have a chance at winning and that one comment could of ruined her whole night.”
Gordon is known for his short temper and hosts Ant McPartlin and Declan Donnelly revealed earlier on that they’d invested in a bleep machine for his appearance on the ITV family entertainment show.
The pair have apologised today after Gordon kept using foul language on the show.
During the Read Your Lips game, one of his guesses appeared to be an expletive beginning with the same letter as the correct word.
After the player eventually won £250, Ant McPartlin turned to the camera and said “I do have to apologise for your language halfway through that.”

A surprised Ramsay asked: “What did I say?”
“It may have sounded like a swear word – might not have been, but it may have sounded like one,” McPartlin said.
