The TV presenter decided to have traditional train tracks fitted after her 14-year-old son Finlay was told he needed a set.
Andrea decided to support Fin, having avoided having them as a teen herself.
Explaining her decision on the ITV lunchtime chat show, she said: "I was supposed to have them when I was a teenager. I had acne, a perm, I was not going to add braces.
“My 14-year-old son just had them done, I was saying you’re so brave, and I thought you’re such a hypocrite because you never did it.
“So I did it! And we’re brace-face together!”
Andrea was all smiles on the panel, with Coleen Nolan and Keith Lemon
After the show had finished, she took to Twitter to share a picture of herself and Finlay with their matching gnashers.
“Thank you for all your kind comments about my braces today on @loosewomen. Fin and I are now Brace Faces together!” she wrote.
“Was nervous about the braces debut, but where better than on @loosewomen! #realwomen,” she added.

Andrea is by no means the first celebrity to have braces fitted as an adult.
