We go to Dr Raymond Lee as well.
My 5 year old also had IV sedation done over a year ago. Unfortunately when we were in Austrialia my boys were petrified of the dentist, so it was nightmare to get them to brush and go for a visit. By the time we saw Dr Lee, one of his baby molars had really decayed, so he had to have it taken out and I was all for the IV sedation (had it done myself when I had a wisdom tooth removed by Dr Lee). The anaestist that did myself and my son is was really nice, Dr Cartis or cutis (can't remember)?? Anyway, to this day my son can't remember having his tooth pulled out and his happy to sit in the dental chair and let Dr Lee do cleaning and small fillings on him WITHOUT injections, so I would say, for my son, it was well worth it.
