A former Texas dentist who left a 4-year-old girl with irreversible brain damage from a botched surgery has walked away with just five years of probation — despite prosecutors seeking 20 years in prison.

Bethaniel Jefferson failed to call 911 for five hours as little Nevaeh Hall’s oxygen levels plunged seven years ago — leaving the now-11-year-old girl needing around-the-clock care and still unable to see, speak, walk or eat on her own.

Her attorney, John Kovach, readily admitted Jefferson “screwed up” as she was convicted Wednesday in Houston of reckless injury to a child by omission.

Prosecutors sought the maximum sentence of 20 years in prison — and the jury initially sentenced her to 10 years, according to KHOU11.

However, it also recommended community supervision, which allowed the judge on Thursday to sentence Jefferson to just five years of probation, the Houston Chronicle said.

“I don’t think justice was served,” Assistant District Attorney Gilbert Sawtelle complained to the paper.

“She failed for five hours … She was more worried about herself than that little girl’s life.”

Nevaeh’s grandmother, Clara Clark, also slammed the verdict as “very unfair.”

“Justice was not served,” she told Fox 26, saying that Jefferson “should have gotten prison time.”

Jefferson “gets to walk free, live her life, going about her business,” Clark said. “Nevaeh won’t get to go to her prom, walk down the aisle and get married, enjoy her birthdays where she can run around and play, which is what a child should do.”

The trial heard how the young girl was supposed to have a routine procedure for a decayed tooth, but was left sedated for hours despite seizing at least three times.

Jefferson’s dental license was revoked just months after the botched procedure in January 2016.

Hall’s family was also awarded a $95.5 million settlement in a civil lawsuit last year, but a plaintiff’s attorney said Jefferson has no money to pay the damages.

The ex-dentist’s attorney, Kovach, had broke down in tears in court while begging for his client not to be put behind bars, according to the Chronicle.

“She screwed up, but to send her to prison is excessive,” he said.

“If she’s going to harm the community, it’s as a dentist and she’s already lost her license.”
