My 5 yr old son needs quite extensive dental work probably about 6 extractions, some fillings and coatings etc. He weigh about 41 lbs. Dentists asked us parents to choose between sedation (3 -4 sessions on the clinic setting) or general anaesthesia (in 1 sitting at the OR); Either one we are nervous for our son. Any opinion on which one will work better for him and for us? Any points about local anaesthesia? Can his body tolerate the general one?
