Dear Tigger.. what should I do?
Our Sammy won't let Mum clean his teeths. She brushes ours regularly. What do you suggest?

Hi toothless Kai, have you tried explaining to Sammy he will end up toothless like you if he does not let your mum brush his teeth?

Perhaps your mum should try making  a game of it and have everyone around so they can take turns getting their teeth brushed.
Getting Sammy used to the tooth brushing game will hopefully help
