Ten-year-old Marta has one big fear: the dentist. But everything changes when a shimmering portal in her mirror pulls her into a dazzling world where toothbrushes talk, rivers sparkle with mint, and courage is the only cure for danger.

In the enchanted Kingdom of Dental Courage, Marta meets Scrab - a clever floss dispenser with a heart of gold - and discovers a sweet but sinister villain: King Caramelis, who wants to cover the land in sugar and fear. To save the kingdom (and maybe herself), Marta must face her biggest fear and learn that bravery doesn't mean not being scared - it means doing the right thing even when you're scared.

Perfect for readers aged 7-11, this charming, funny, and inspiring story helps kids build confidence, learn the value of dental health, and discover the magic of believing in themselves.
