K.B.
My son brushed his teeth better with the electric tooth brushes and I also set a timer for him.
Plus a trip to the dentist who explained the importance of brushing his teeth.
A big bonus for me was my son lost his first tooth at the age of 4 and I told him the tooth fairy would refuse any dirty teeth, so when he lost his 2nd tooth the tooth fairy left him a special note on how clean his tooth was
