All the good reasons to brush your teeth back then eh ... Ah yes the reason i brushed religiously :))) amazingly much of this 50-60's equipment survived into the 90's. my dentist had just a little newer stuff back then and if you think going to the dentist is a daunting thing now you can only imagine dr frankenstien's chair with the assortment of drills ,suction devices,needles and spitoons :)))
