In the absence of pain i would tend to think that the crack is superficial. If there is major damage to the tooth the dentist will make a small crown
for the tooth. We still make these stainless steel crowns and cement them into place and they serve very well and are shed when the deciduous is replaced. The new bonding
techniques are changing the way we treat these sorts of issues, and can restore "baby teeth" very well for the few years that they are required to serve.
The decision to anesthetize a child must be made between you and the treating doctor. Personally i prefer not to use gas on children
if it can be helped. The pedodontists are skilled in providing this type of care with minimal use of major nervous system depressants.
