A Manhattan dentist sprayed water on a patient and then reached under her blouse and grabbed her breast, police sources said.

Dr. Majid Khamesi, of the Advanced Family Dental Center, was charged Wednesday with forcible touching, a misdemeanor, two days after he allegedly groped the woman in his practice at 30 E. 40th St.

A clerk in the office told The Post that the patient is a 34-year-old woman who came there Monday to have her braces adjusted. The patient left without any drama, so the clerk said she was surprised when police stopped by at lunchtime Wednesday.

A police source said there have been similar complaints against this dentist in the past. But the clerk said he’s never had any trouble with patients.

“He has so many women patients in his office, so many,” the clerk said. “It’s impossible he can touch anyone. There are not even doors in the office.”

The alleged victim has been a patient there since 2012, the clerk said.

“That’s what is weird,” she said. “She’s not even a beautiful woman. I don’t have any clue why she’s making this claim.”

The company’s website states that Khamesi earned a doctorate at Columbia University School of Dental and Oral Surgery and that, “Now, one of Manhattan’s leading dentists can be your dentist.”
