Via Dentata

Two events to get excited by. We had a new toilet installed. There was a silent dribble down the bowl sending our water bill up. I am just flushed with that success but there was also the visit to the dentist.  Nothing like an outing to get you out of the house even if its down the via dentata.  (Tooth Road).  I had a filling done, a scale and clean, a fluoride coating and a general checkup for $60.  Dentists are cheap in the country.  It seems my use of tooth picks is ok but I am too rough and damaging on the gums.  She recommended I use a Pikster. I've never heard of it either. It seems I need a size 0. What are these baby teeth?
