Christina Hall issues a health-related warning for her fans. The Christina on the coast star shares a scary story about a root canal gone wrong as she encourages her followers to contact their dentist.

“I think it's important to share a quick PSA,” she begins the update on her Instagram Story, recalling a dental injury she suffered as a teenager that resulted in an emergency root canal.

“In 2020, my dentist saw via [X-ray] the previous root canal showed signs of infection. So I went and did it again,” she explains.

Last week, Hall said the infection returned without any signs or symptoms.

“So I had an infection that I [have] zero symptoms to last for years!!' she exclaimed. “Pretty disturbing.”

Hall notes that she will “take care of it via explant next week,” but is wary of other possible consequences of the infection.

“Letting an infection persist for so long can cause all kinds of health complications,” she says. “Without a root you can't feel that there is a problem.”

She adds: “Of course, since our phones are listening to us, I've been reading about all kinds of problems with old root [canals]. If you've ever had one, get yours ASAP.”

Hall's latest health scare comes after she revealed in 2022 that she had been diagnosed with mercury and lead poisoning.

“My scan said I have mercury and lead poisoning,” the HGTV star revealed on Instagram. “Most likely from all the dirty houses I've been in (the bad stuff) and I have an overgrowth of bacteria in the small intestine. So we detox all this first through herbs and infusions and then see how I feel and get the implants.”

Hall had previously wondered whether her breast implants were the cause of her illness as she wrote in an earlier post“I have had unexplained health problems for years, and now I am considering the thought that this could be related to breast implants.”

Hall also said at the time that her lip fillers had dissolved and listed several other conditions she was dealing with, including Hashimoto's disease, Raynaud's syndrome, polycystic ovary syndrome, unexplained rashes, joint and muscle pain, dry eyes, acid reflux and brain fog. .

More recently, Hall celebrated her third wedding anniversary with husband Josh Hall during a romantic getaway to Los Cabos, Mexico, last month.

The 40-year-old designer shares daughter Taylor, 13, and son Brayden, 8, with her ex-husband, Tarek El Moussa. She also shares son Hudson, 4, with her ex-husband, Ant Anstead.

Last year, the Halls opened up about their relationship in an interview with ET.

“We're kind of in our own world,” Christina said, as the couple discussed the simple tradition that keeps them connected.

'Do you know what is romantic? Coffee at 6:30 every day,” Josh said.

“That's pretty nice,” Christina replied.
