The Tooth Fairy wants children to send her letters and drawings about how they look after their teeth.
She's working with Jersey Post and the government to encourage children to beat their fears of the dentist and share their positive experiences.
Children can write to the tooth fairy or send a drawing about visiting the dentist, losing their first tooth and keeping their teeth clean.
Sarah Evans, Interim General Manager – Primary, Prevention, Adult Therapies and Community Dental, says good oral hygiene is important at any age.
"Engaging children and helping them to adopt a good routine of twice daily brushing and mouth care early on, creates long-term healthy habits."
"We’re delighted to be supported by Jersey Post in enabling children to send letters to the tooth fairy without the need of a stamp and helping deliver her letters back to them."
Letters can be sent to the Tooth Fairy, on Treetop Lane, Tooth Fairy Land by the 15 July.
If youngsters include their address in the letters and drawing they may receive something in return from the fairy herself.
