M.O.
My son needed fillings at 3 and 4 (bad genes). The dentist we go to doesn't use the scary terms of cavity, filling, drill, or other dentistry words that may frighten small kids. For example, he used "sleepy teeth" to describe the shot that my son never felt because of the nitrous......To this day, my son has no idea he has fillings! I say find a great pediatric dentist that you can trust. Mine is Dr. Dave from Small Smiles Dental in Naperville. I highly recommend him. Good luck.
