Jenny McCarthy solved her medical mystery.

Four months after describing a horrific illness that had growths developing on the actress’s eyes and her teeth falling out, she explained exactly what led to her symptoms on Maria Menounos’ “Heal Squad” podcast.

The 53-year-old’s troubles with severe mycotoxin poisoning and mold toxicity began when the root canal she had at 20 didn’t get “cleaned out all the way.”

On Tuesday, McCarthy noted that she developed a jawbone infection due to “three … little toxic pools hiding underneath [her] wisdom teeth.”

“There was an infection left in there and a bone grafted on top of it, so I went on my merry way with infection brewing in my bone,” she added.

Despite having multiple oral surgeries removing her teeth, McCarthy “just kept getting infected.”

Her remaining symptoms included “awful” insomnia and leg cramps that were so intense she’d “wake up crying.”

The “Masked Singer” judge went on to develop growths on her eye with “little lesions” that “looked like the nastiest whitehead pus-filled eraser top.”

She said as much in a November 2025 People interview.

“I had one infection that turned into another and another, and then I had these growths show up on my eyeballs,” McCarthy told the outlet last year. “My teeth were falling out, implants falling out.”

The ex-“View” co-host clarified at the time that she’d undergone nine surgeries and been “on antibiotics for a year” and “eating soft foods only.”

McCarthy quipped, “People should actually feel a little sorry for me!”

She speculated that she was finally “past the storm.”

McCarthy gave a treatment update on Tuesday, saying she was three months into a “heavy-duty mold protocol” that will “probably” last one year.

The former Playboy model, who is also taking “like, a hundred supplements,” acknowledged that she still has “a long way to go.”
