It was fantastic to see Manchester graduate and Specialist in Paediatric Dentistry, Dr Hannah Walsh, appearing on CBBC Newsround.
Her appearance was to raise awareness of tooth decay, and how it can impact kids and their ability to learn in school.
She came across really well and provided all the key tips to help children better look after their teeth and avoid problems in the future.
