Kerry Katona has been "in agony" after undergoing emergency dental surgery

She wrote in her new! magazine column: "I've been in a lot of pain this week - it's been so tough.

"The lumps in my jaw I wrote about last week turned out to be an infection, so I had to get three root canal procedures at once.

"I've been in agony ever since and just wanted to stay in bed - but with work so hectic right now, I can't do that."

She thanked Wish Dental for doing an "amazing" job taking care of her, while revealing the painful aftermath of the procedures.

She added: "I'm filming [UK reality show] 'Celebs Go Dating' and having to act cheery when I'm in agony.

"I just want to get back to being the Kerry everyone wants. Fingers crossed for some recovery."

Meanwhile Kerry, 44, recently said she wants to have another baby because she feels "lonely".

Kerry - who has daughters Molly Marie, 23, and Lilly-Sue, 22, with first husband, former Westlife band member Brian McFadden, Heidi, 18, and Max, 16, with second husband Mark Croft, and daughter Dylan-Jorge, 10, with the late George Kay - admitted: "I am feeling really broody - I want to have another baby. I'm just lonely at the moment.

"I'm single and all of my kids are growing up - DJ starts high school this year and she'll be the last one to fly the nest.

"When I'm at home, my son Max is always in his room, and my girls are all growing up."

Kerry has been looking into her options to have a baby if she decides to go for it without a man in her life.

The star - who split from her fiancé, fitness trainer Ryan Mahoney, 36, earlier this year - said: "Sperm donor? Why not! Or maybe I'd just find a younger man with strong swimmers."
