In a case of a toothless man in a topless bar, a Manhattan chef claims a sensitive stripper slugged him for insulting her mothering skills.

David Kupferstein, 36, stopped with pals at the Hustler Club in March 2015 when one of the dancers chatted up the group.

“She kept on talking to me,” he recalled. “She kept on having drinks with us. Some of my friends were throwing money at her. She told me all about herself and her family and her children . . . and how they were f–king up with the police.

“I said, ‘It sounds like you are a bad mother.’

He added, “ I guess she didn’t like it.”

The dancer punched Kupferstein as he was sipping his drink, knocking out his left front tooth in the process, he charges in a Manhattan Supreme Court lawsuit against the Midtown West jiggle joint.

“Within seconds, three or four bouncers surround me, escorting me out,” he said. “They bring me to the front. After a couple of minutes they found my tooth on the floor and brought it back to me.”

The manager allegedly pledged to pay the private chef’s dental bills, but later reneged, Kupferstein claims.

The injury left Kupferstein with a gap in his grin until he was able to get a temporary fake tooth.

“One of the restaurants I was interviewing for was called, ‘Smile.’ The irony was very thick,” he said.

Kupferstein, who is single, expects years of expensive dental work ahead, including possible gum surgery — and is suing for almost $1 million in damages.

“We want the Hustler Club to be held accountable,” said his lawyer, Steven Wolff.

A lawyer for the West Side Highway strip club declined comment. A manager didn’t return messages.

Kupferstein said he “felt ashamed” for having been in the strip club, but doesn’t think the punishment fit his crime.

“I guess it is sort of insulting to tell a woman she is a bad mother,” he admitted. “I felt we had that kind of rapport.”
